(Nuclear Physics) a nuclear reactor using water as coolant and moderator at a pressure that is too high to allow boiling to take place inside the reactor. The fuel is enriched uranium oxide cased in zirconium. Abbreviation: PWR
Until about 10 years ago, she says, severe-accidentmodels tended to ignore the quantity of radioactive aerosols that might be released, but recent studies have shown that a pressurized-water reactor, like N-Reactor, might generate tons.
The AP1000 is a 1,100 megawatt electric pressurized-water reactor that includes passive safety features that would cool down the reactor after an accident without the need for human intervention.
Also to be covered at the meeting are: potential approaches to resolve generic safety issue (GSI)-191 on assessment of debris accumulation on pressurized-water reactor sump performance; amendment to the design control document for the certified advanced boiling-water reactor design; long-term core cooling approach for the economic simplified boiling-water reactor design; and the license application for the mixed-oxide (MOX) fuel fabrication facility under construction in Aiken, S.C.
