Westinghouse could build AP1000 reactors at Czech nuclear site – Power Engineering®️

Westinghouse Electric Company signed MOUs with seven companies to potentially deploy the company’s AP1000 nuclear reactor for the Dukovany 5 project in the Czech Republic.
Westinghouse Electric Company signed memorandums of understanding (MOUs) with seven companies to potentially deploy the company’s AP1000 nuclear reactor for the Dukovany 5 project in the Czech Republic.
Westinghouse is one of three finalists for the job. The other two are EDF and Korea Hydro & Nuclear Power.
State power company ČEZ has said it is planning to build one Generation III+ reactor at the Dukovany site, with a maximum installed capacity of 1,200 MW. 
The Czech companies are Královopolská, which provides technological steel structures; Vítkovice, an engineering group which supplies modules for nuclear power plants; I.B.C. Prague, which develops, produces and services industrial valves for the nuclear and energy industries; I&C Energo, an electrical and engineering company which services command-and-control systems and industrial information systems; NOPO, which specializes in gantry cranes, paint shop platforms, manipulators and overhead cranes; Sigma Group, which produces centrifugal pumps designed for use in energy management; and Infer, which specializes in piping systems, valves and metallurgical material.
The MOUs, signed at the Ministry of Industry and Trade, also extend to other potential projects in Central Europe.
The Czech Republic’s 2015 state energy policy aimed for nuclear energy to. make up more than half of total electricity production in the long term, up from around one-third at present. To meet that goal, the government plans to add up to 2,500 MW of nuclear capacity in the next decade.
The AP1000 is a two-loop pressurized water reactor (PWR) which evolved from previous Westinghouse PWR designs. Its design aimed to reduce the number of components to help cut capital costs and reduce the need for large cooling towers and other equipment. The reactor was created to produce a net electrical output of 1,117 MWe.
The reactor coolant system includes two heat transfer circuits, each containing one steam generator, two reactor coolant pumps, and a single hot leg and two cold legs for circulating coolant between the reactor and the steam generators. The system also includes a pressurizer, interconnecting pipes, and the valves and instrumentation needed for operational control.
Unlike previous generations, the AP1000 plant’s passive safety systems are intended to require no operator intervention in the event of a design-basis accident, like a coolant-pipe break. Rather than relying on active components, such as diesel generators and pumps, the AP1000 plant relies on natural forces – gravity, natural circulation and compressed gases – to keep the core and the system from overheating. No pumps, fans, diesels, chillers or other active machinery are used, except for a few valves that automatically align and actuate the passive safety systems.
Westinghouse’s AP1000 design was certified by the U.S. Nuclear Regulatory Commission in 2005. The company currently has six AP1000 nuclear plants operating or under construction. Four are operating at two separate sites in China: two at Sanmen Nuclear Power Station and two at Haiyang Nuclear Power Plant.
Two AP1000 units also are under construction at the Alvin W. Vogtle Electric Generating Plant near Waynesboro, Georgia. Construction at Vogtle has been bogged down by numerous delays and rising costs. In December project engineers told the Georgia Public Service Commission Vogtle Unit 3 wouldn’t meet the completion range of July 2022 to September 2022 set by Georgia Power, who shares ownership of the project. Engineers told state regulators a more accurate completion target might be November 2022 to February 2023. They said Unit 4 may not come online until sometime in late-2024.
When they go into service, Vogtle units 3 and 4 would be the first new U.S. nuclear generation reactors since Tennessee Valley Authority’s Watts Bar 2 began operating in 2015.
Plans for two other AP1000 reactors at the Virgil C. Summer Nuclear Plant in South Carolina were canceled in 2017. The decision came in the wake of Westinghouse’s bankruptcy. The Toshiba subsidiary filed for bankruptcy, citing over $6 billion in debt.
