The reactor can use 5% enriched uranium oxide fuel, reprocessed uranium fuel or 100% mixed uranium plutonium oxide fuel, clad in Areva's M5 variant of zirconium alloy. [11] [12] The EPR is the evolutionary descendant of the Framatome N4 and Siemens Power Generation Division "Konvoi " reactors. [13] [14] Siemens ceased its nuclear activities in ...
The actuation of these valves depressurizes the reactor vessel and allows lower pressure coolant injection systems to function, which have very large capacities in comparison to the high pressure systems. Some depressurization systems are automatic in function, while others may require operators to manually activate them.
The first two plants in Kashiwazaki-Kariwa (block 6 & 7) reach total life operating factors of 70%, meaning that about 30% of the time, since commissioning, they were not producing electricity. [ 21 ] [ 22 ] For example, in 2010 Kashiwazaki-Kariwa 6 had an operating capacity of 80.9%, and an operating capacity of 93% in 2011. [ 23 ]
Passive nuclear safety is a design approach for safety features, implemented in a nuclear reactor, that does not require any active intervention on the part of the operator or electrical/electronic feedback in order to bring the reactor to a safe shutdown state, in the event of a particular type of emergency (usually overheating resulting from a loss of coolant or loss of coolant flow).
This is a list of all the commercial nuclear reactors in the world, sorted by country, with operational status. The list only includes civilian nuclear power reactors used to generate electricity for a power grid.
The AP1000 design traces its history to two previous designs, the AP600 and the System 80.. The System 80 design was created by Combustion Engineering and featured a two-loop cooling system with a single steam generator paired with two reactor coolant pumps in each loop that makes it simpler and less expensive than systems which pair a single reactor coolant pump with a steam generator in each ...
Jaitapur Nuclear Power Project is a proposed nuclear power plant in India. If built, it would be the largest nuclear power generating station in the world by net generation capacity, at 9,900 MW . [ 3 ] [ 4 ] The power project is proposed by Nuclear Power Corporation of India (NPCIL) and would be built at Madban village of Ratnagiri district in ...
According to the operator, the leak forced to limit the plant output down to 300 MW, but was not serious and was to be repaired in a day. [106] An incident occurred at unit 2 on 10 December 2020 at 12:22. Because of valve repair work, excessively hot water flowed to the reactor water clean-up system filters.
