China Will Add Two More AP1000 Nuclear Reactors

0

China’s State Council has approved two AP1000 nuclear reactor units for State Power Investment Corp.’s (SPIC’s) Lianjiang Nuclear Power Plant in Zhanjiang, Guangdong province, reactor technology supplier Westinghouse said on Oct. 12.

If built, the units will become ninth and tenth reactors based on Westinghouse’s Generation III+ advanced reactor technology in China. Four AP1000 units are already currently operating in China: Sanmen 1 and 2 in Zhejiang province and Haiyang 1 and 2 in Shandong province. The four reactors were commissioned in 2018.

Another four CAP1000 reactors—China’s licensed adaptation of the AP1000—are under construction at the Sanmen and Haiyang plants. Sanmen 3 and 4. China National Nuclear Corp. (CNNC) kicked off construction of the second phase at Sanmen in June 2022, while Shanghai Nuclear Engineering Research and Design Institute (SNERDI), a SPIC affiliate, poured first concrete for Haiyang’s second phase in July 2022. The State Council approved the two projects in April. By Sept. 25, SNERDI, a general contractor for both projects, reported it had separately hoisted in place containment vessels at Haiyang 3 and Sanmen 3.

SNERDI is also building CAP1000s at Lianjiang 1 and 2. The company on Sept. 28 announced it began excavation for the Lianjiang plant’s first phase. The site is designed to host a total of six 1.2-GW reactors, said SNERDI.

Speeding Toward ‘Nth-of-a-Kind’

Westinghouse in a statement congratulated SPIC on adding the AP1000-derived plants to its growing fleet. It said the AP1000 plant “is the only operating Generation III+ advanced reactor with fully passive safety systems, modular design, and has the smallest footprint per MWe on the market.” The reactors at Sanmen and Haiyang “utilize the most advanced, proven technology and have set industry records with their outstanding startup, availability, and operational performance. One unit at the Haiyang site is generating both electricity and steam for district heating,” it noted.

Excellent Planning and Focus on Safety Lead to Successful Feedwater Heater Replacement Project

0

Nuclear power plant outages are filled with intense work and tight schedules. A feedwater heater replacement project at Duke Energy’s Oconee station in South Carolina shows how teamwork coupled with excellent planning and a focus on safety can lead to success.

Feedwater heaters (FWHs) are an integral part of a nuclear power plant’s thermodynamic cycle. Depending on a plant’s design, there may be low-pressure FWHs installed between the unit’s condenser and deaerator, while high-pressure FWHs are often installed between the deaerator and steam generators. The number of FWHs installed is designed to optimize thermal efficiency. Each FWH typically utilizes steam from an extraction point placed at various stages of the plant’s steam turbines.

Over time, the tubing in FWHs can erode, so it’s not uncommon for the components to eventually require repair or replacement to ensure long-term efficient plant operations. In May 2022, Oconee Nuclear Station replaced two vertical 60-ton FWHs in Unit 3 (Figure 1). ARC Energy Services Inc., Sarens Nuclear & Industrial Services Inc., 3SPACE Inc., and Structural Integrity Associates Inc. teamed up to complete the job in just 12 days and one hour. The project required 700 welds and more than 42,400 total hours of work, including planning, pre-outage, and outage activities, all completed safely.

Project Responsibilities

3SPACE performed laser scanning and created a point cloud to capture all interferences requiring removal before the feedwater heaters could be replaced. ARC then generated a 3D model animation to visualize the process during planning. ARC also engineered a sliding rail system, controlled by hydraulic pumps, which was installed in the heater bay crane aisles to mobilize needed rigging equipment for the FWH replacements, including:

The old FWHs were removed with the TLD (Figure 2), down-ending onto the rock-over tailing cart and trunnion cart while maintaining control with the hydraulic sliding rail system. The new FWHs were up-ended using the same equipment and set into location so 3SPACE could perform metrology to align the 24-inch inlet and outlet nozzles (Figure 3).

Once all alignment was completed the team installed all piping and interferences per new design drawings. Structural Integrity performed phased array ultrasonic testing (PAUT) on all 24-inch nozzle welds before and after post-weld heat treatment with no rejections.

Teamwork and Innovation Overcomes Challenges

One of the biggest challenges was keeping the team safe and healthy. Several work groups had people out due to COVID-19. The team minimized that potential issue by practicing good hygiene and following COVID protocols that were in place.

4. The new FWH is shown here as it’s being lowered, with the knuckle boom crane pictured in the foreground. Courtesy: ARC

Another challenge involved crane use because two major projects were ongoing on Unit 3, which limited crane availability. Conflicts were avoided through effective communication and scheduling with Duke Energy work groups. ARC also provided an alternate option of using the knuckle boom crane (Figure 4) in some situations.

The project team utilized special engineered equipment to remove and replace the two 60-ton FWHs in the limited space and time available. The work was done safely with no injuries or first aid incidents, even while COVID-19 was a widespread threat. The success of the project demonstrates to the industry that with proper planning and focused execution jobs can be accomplished effectively and efficiently. The FWH project was completed below budget and ahead of schedule with zero injuries in 42,400 hours worked.

An Effective Safety Program

As a contractor for Duke Energy, ARC works closely to mirror the client’s safety culture and protocols. The company believes that all injuries can be avoided and promotes a safety-conscious environment on the job and off the clock. ARC says safety is 24-7 and it demonstrates that in all engagements with clients and staff.

The ARC safety program used at Oconee—and on all of the company’s projects—is designed to educate and guide employees and subcontractors toward a safe and healthy working environment. In addition to a comprehensive Environmental Health and Safety (EH&S) policy and procedure, and required training for compliance with all applicable safety and health standards, employees participate in a weekly safety training session designed to cover the latest best safety practices pertaining to the power industry.

Training and risk assessments include regulatory standards and applicable behavioral-based safety developments. Management’s commitment to safety is the foundation of the ARC program. Managers lead by example and guide crews to perform at the highest level of safety consciousness. At the beginning of each shift, teams complete a job hazard analysis to identify the assigned tasks, associated risks, and how to mitigate those risks and execute the work without incident.

Construction Quality and Craftsmanship

Using ARC’s robust Quality Management Program (QMP), managers set solid expectations and plans months before project initiation. Project quality requirements—from implementation to final offloading of the FWHs—were set and followed precisely.

The project’s quality team included four non-destructive test (NDT) and quality control inspectors (QCIs), who monitored every detail of the code, plans, and procedures used. Structural Integrity provided highly qualified PAUT specialists, who performed flawlessly and with precision.

Quality went beyond welding. It encompassed the development of quality plans, document controls, filler material controls, professionalism of each team member and their willingness to get things done right the first time, training, and following each element of the QMP. The team successfully completed the project making almost 700 welds with each being inspected, documented, and tracked (Figure 5).

Just like safety, quality takes a team effort. Without the amazing team ARC formed, quality would have suffered. Each team member contributed to the elevated quality of this project in the following ways:

Bespoke pit fan motors with fin cooling

0

Menzel Elektromotoren has designed and manufactured three powerful 6600 V squirrel cage motors as integral components for pit fans. The customer specified cylindrical motor casings as compact as possible. The greatest challenge was to implement the required rated power of 1700 kW in cylindrical casings. Menzel therefore designed fin-cooled motors (cooling type IC 411) in frame size 630, an extremely unusual design for motors this large. The manufacture is complex but the result is optimal for the constricted installation conditions. In order to save additional space, all connection cables are routed out of the motors and the terminal boxes are mounted outside the fans. Since the driven fan wheels are mounted directly on the motor shafts, the motor bearing must compensate additional high loads: radial loads up to 20700 N and axial loads up to 27000 N. For the required bearing service life of 100,000 hours, Menzel implemented a special rolling bearing setup. In addition, the motors have a second shaft end for a holding brake. The three-phase squirrel cage motors are designed for operation on a frequency converter (duty type S9) with speed changes and reversal of the rotation direction. This allows the pit fans not only to ventilate the mine, but also to extract dangerous firedamp if necessary.

Garbage loads being efficiently compacted by refuse trucks fitted with SKF/Lincoln automatic lubrication systems

0

The success of an automatic lubrication system installed by SKF/Lincoln on two refuse compactor trucks resulted in increased uptime, machine availability and personnel safety, urging the satisfied customers to call for the same lube solution on three more trucks.

According to SKF/Lincoln’s Application & Export Sales Engineer, Donatien Makopo, this was a new project for SKF/Lincoln. “We are extremely proud of the fact that our first compactor refuse truck lubrication installation impressed not one but two customers, a renowned truck manufacturer as well as a prominent crane builder.”

Makopo explains that the customers’ initial practice to manually lubricate all grease points on the refuge compactors caused two main problems. “In addition to some points being overlooked as they were covered in dirt, over-greasing was causing breakdowns and subsequent costly downtime. Over-greasing also led to unnecessary grease wastage which added to the customer’s costs. Already familiar with the brand due to lubrication installations having been done previously by a SKF’s Authorised Distributor in Cape Town, the customer approached us to assist them with an automated lubrication solution.”

“We did not hesitate in recommending the SKF/Lincoln progressive lubrication system with P203 & KFGS1 pumps as the best solution for our customers. In addition to the fact that the units are easy to maintain, readily available stock mitigates shortages in the supply of pumps and SSV lubricant/grease metering devices.” Makopo adds that alongside proven product quality and reliability, price competitiveness was also key in securing the order.

The new generation P203 Quicklube pump can lubricate up to 250 lube points and is the answer for small to mid-sized machines and systems. The pump is equipped with numerous product advantages as standard including weather-resistant pump housing material not susceptible to UV rays, a larger filling port for easy filling of the reservoir and a strong “Polar” stirring paddle that ensures good lubricant mixing, even at temperatures of up to -40° C. Moreover, the pump is IP6K9K protected against damage and moisture.

The proven SSV progressive lubricant metering device in solid block construction is easy to monitor and delivers a high operating pressure ensuring optimum reliability even at temperatures below freezing. Featuring a maximum operating pressure of 350 bar, these piston metering devices reliably divide the incoming lubricant in predetermined individual quantities. As the devices are not fitted with fault-prone rubber seals, they can be used with high backpressures, making them ideally suited to a wide range of temperatures.

SKF/Lincoln received the first order to fit automatic lube systems on two refuse compactor trucks on 12 May 2022. Despite a few delays on the customer’s side, both trucks were completed on 27 May 2022. The project was a joint venture between the SKF/Lincoln team in Johannesburg who completed the installations at the customer’s premises. The trucks were transported to KwaZulu-Natal for final commissioning by the local SKF/Lincoln team and then delivered to the Durban customer.

Due to the success of the first project, the customers placed a repeat order on 14 June 2022 for the fitment of three more trucks. We again faced some delays from the customer’s side but we still managed to successfully complete installation and commissioning of all three trucks within six weeks,” concludes Makopo.

FRAGTrack™ Gantry leverages real-time oversized detection through artificial intelligence (AI). This unique machine learning capability is applied to real-time detection accomplished within seconds and alerts syndicated via fleet management systems (FMS), email, or SMS for the re-routing of trucks. Operators can also predetermine customisable oversize limits, enabling a reduction in crusher blockage/damage frequency due to oversize material.

Orica Vice President, Raj Mathiravedu, said:

”The full adoption of AI technology into our architecture, coupled with our strategic partnership with Microsoft, allows us to expedite the delivery of capabilities that were not previously possible, and FRAGTrack Gantry is another example of how we are leveraging AI to help deliver intelligence and value to our customers.”

The reliable and accurate fragmentation information from FRAGTrack™ Gantry enables customers to optimise their drill and blast operations for downstream processes without impacting the haul circuit operation. The addition of a Gantry option complements the suite of FRAGTrack™ measurement systems currently available for shovel, crusher and conveyor mounted configurations.

Nigeria to pay $496 million to settle Indian firm’s claim over Ajaokuta steel

0

The Nigerian government says it has agreed to pay $496 million to settle a multibillion dollar claim by Global Steel Holdings Limited over the control of Ajaokuta Steel Company.

Attorney-General Abubakar Malami said the federal government will pay the company $496 million instead of $5.258 billion demanded by the firm, to settle the dispute. The deal was reached under the alternative dispute resolution framework of the International Chamber of Commerce, said a statement by Mr Malami’s spokesperson, Umar Gwandu.

The dispute followed the federal government’s revocation in 2008 of an agreement that handed control of the steel works and the National Iron Ore Mining Company to Global Steel Holdings Limited, an Indian firm. In cancelling the deal, the Umar Yarádua administration said the terms of the concession at the time were not favourable to the country.

The steel company, located in Kogi State, was conceived to serve as the pillar of Nigeria’s industrialisation. It was built by the Soviets between 1979 and the mid-1990s but has never produced steel as the project was never completed. It was also mismanaged.

The government said the seeds of the disputes can be traced to five contracts entered between 1999 and 2007 that gave complete control over the Nigerian steel space to one company group, Global Steel group.

The justice ministry said the decision to terminate the contracts by a new administration in 2008 was taken contrary to legal advice by the Federal Ministry of Justice, which cited the termination cost in the form of damages. It said had the government waited for 55 days, the pact would have terminated lawfully and the government would have collected more than $26 million from Global Steel.


“This was because the firm appeared unable to pay the first tranche for the Ajaokuta shares before the first anniversary of the agreement (25 May 2008),” the statement said.

“This failure would have given Nigeria a right to over $26m as liquidated damages under cl.12 of the Ajaokuta Share Purchase Agreement.

“Global steel, in consequence, took the federal government to the International Chamber of Commerce, International Court of Arbitration, Paris, commencing arbitration in 2008. Although the Federal Government negotiated a settlement in May 2013, the previous administration failed to implement its settlement agreement,” the statement said.

In May 2020, Global Steel threatened a resumption of the arbitration and announced an anticipated claim in damages of over $10-14 billion against Nigeria.

The government said it agreed to pay over $400 million to settle the case once and for all after engaging PwCNigeria to do a comprehensive review to ensure taxpayers are protected.

With this development, the statement said President Muhammadu Buhari has now “rescued the steel industry from interminable and complex disputes as well as saving the taxpayer from humongous damages.”

“The Office of the Attorney General of the Federation and Minister of Justice grappled with the inherited problem by adopting a blueprint of seven principles for the cost-effective resolution of contractual disputes wherever they occur. They are the use of institutional mediation, choice of FGN counsel, the use of financial advisers with reputational capital, the importance of not discouraging foreign investment, fiscal responsibility, transparency, and the recognition that joined-up government produces superior outcomes,” Mr Gwandu said.

Freudenberg S.A.F.E.air secures ISO-compliant pressurisation and filtration in mining vehicles

0

Freudenberg Filtration Technologies has devised the Freudenberg S.A.F.E.air filtration solution to reduce airborne respirable contaminants and CO2 levels in mining vehicle cabins, fulfilling the ISO 23875 requirements for safe heavy equipment cabins.

Freudenberg S.A.F.E.air secures ISO-compliant pressurisation and filtration in mining vehicles

Freudenberg S.A.F.E.air helps improve operator safety and equipment integrity in a challenging workplace: mining work and related activities with high particle exposure can compromise operator health or damage crucial equipment components.

To a large extent, the world’s economy thrives on resources from considerable depths: coal, rare earths, and iron ore serve as raw materials for many industries, but require extensive mining before they can be processed further. Given the consistently high demand for those materials, the mining sector to this day has seen considerable growth, with the revenues of the 40 most important global mining companies totalling US$656 billion in 2020.

As crucial as mining is, as challenging are the industry’s working conditions: from asbestos to silica, contaminants can enter the cabins of mining vehicles – such as haul trucks, wheel loaders, and bulldozers – either through air vents or via the operators themselves. Other than causing severe health effects, contaminated air can damage mining vehicles, leading to premature mechanical and electrical breakdowns.

Meeting ISO 23875 requirements

“Ensuring the health and safety of vehicle operators, as well as the functionality of mining equipment is of utmost importance, and a challenge we readily took on”, says Stephen Gledhill, Manager Segment Mining at Freudenberg Filtration Technologies.

Effective operator protection re-quires cabin pressurisation and filtration as stipulated by the international norm ISO 23875. According to ISO 23875, fresh air supply and/or air recirculation must keep concentrations of particulate matter below 25 mg/m3, while maintaining pressurisation and CO2 limits: the minimum sustained pressurisation inside operator enclosures is 20 Pa, and 200 Pa at most. CO2 concentrations must not exceed the ambient CO2 plus 400 ppm. The standard CO2 present in the earth’s atmospheres lies between 250 to 500 ppm.

Freudenberg S.A.F.E.air for safe operations

Reducing contaminants and keeping CO2 concentrations within prescribed limitation calls for a versatile solution: Freudenberg Filtration Technologies has devised Freudenberg S.A.F.E.air, a multi-stage filtration solution for ISO 23875 compliant cabin pressurisation and filtration. The Freudenberg S.A.F.E.air system comprises two pre-cleaning filters as well as two high-flow HEPA filters for particle separation. The two pre-cleaning elements protect the HEPA filters from heavy dust expo-sure and ensure longer filter life.

Air entering the Freudenberg S.A.F.E.air system first passes through a cyclonic dust ejection system that filters out heavy dust particles (>5 μm), before the second pre-cleaning filter takes care of coarse dust particles (1 – 5 μm). Two stages of HEPA filters then eliminate 99.995% of sub-micron particles, achieving a full cabin air exchange within 20 seconds. In addition to filtration of outside air entering the cabin, Freudenberg S.A.F.E.air also draws and filters air from within the cabin, ensuring cabins are dust free according to ISO 23875 requirements.

The HEPA-filtered air re-enters the vehicle cabin via the air vents into the occupants’ breathing zone, while also allowing some air to escape the system for fresh air exchange. Thus, Freudenberg S.A.F.E.air provides hospital grade air at ambient CO2 levels and further continuously monitors CO2 levels inside the vehicle and remotely via telemetry. This is essential because high CO2 levels are a major concern of miners, due to its association with fatigue and drowsiness and, subsequently, accidents.

A solution for low maintenance

In addition, the Freudenberg S.A.F.E.air system delivers a constant minimum required pressure of 100 Pa, preventing any contaminants from entering the cabin from outside; for example, through worn door seals. Thanks to the limited dust ingress, the system provides protection to air-conditioning components like fans and evaporators, abolishing premature failure due to contamination.

“Besides reliably protecting operators, Freudenberg S.A.F.E.air also reduces the maintenance of electrical cabinets and control rooms, saving mining companies cost-intensive vehicle downtime, and maintenance costs,” Gledhill comments.

The Director General of the National Office of Hydrocarbons and Mining (ONHYM), Amina Bengatra, provides new details on the Morocco-Nigeria gas pipeline and its impact on the region. This article is a press review of the weekly magazine La Vie Éco.

Announced a few years ago, the strategic Morocco-Nigeria gas pipeline project is currently in the detailed engineering study phase, Amina Bengatra, Director General of the National Office of Hydrocarbons and Mines (ONHYM), reported in the Weekly. Environmental life.

On the sidelines of the second edition of the Conference of Member States of the “MSGBC Oil, Gas and Power” sedimentary basin organized in Senegal in early September, the DG of ONHYM explained that this large-scale project will “contribute to the creation”. An integrated North-West African region, accelerating West Africa’s access to energy and accelerating electrification projects for the benefit of the people”.

This mega project spans 13 countries along the Atlantic coast and includes three landlocked countries. It will have a direct positive impact on more than 340 million people, create wealth for countries and neighbours, and create a decisive impetus for the emergence and development of projects.

According to ONHYM’s DH, the Morocco-Nigeria gas pipeline should contribute to the creation of a competitive regional market for electricity, the exploitation of clean energy, and the industrial and economic development of all countries. This requires growth in several sectors, including agriculture, manufacturing, mining, flaring and gas exports to Europe, the weekly report said. Environmental life.
