Exempel på hur du använder BWR i en mening

• The main difference between a BWR and PWR is that in a BWR, the reactor core heats water, which turns to steam and then drives a steam turbine.
• This period also included the development of the Benedict–Webb–Rubin (BWR) equation of state which has since become an industry mainstay and provided the basis for Kellogg's lead in cryogenics.
• Boiling water reactors (BWR), pressurized water reactors (PWR), and heavy-water reactors (HWR) operate with thermal neutrons, while breeder reactors operate with fast neutrons.
• There are three varieties of light-water reactors: the pressurized water reactor (PWR), the boiling water reactor (BWR), and (most designs of) the supercritical water reactor (SCWR).
• Normally, the critical heat flux (CHF) corresponds to departure from nucleate boiling (DNB) in pressurized water reactor (PWR) and dryout in boiling water reactor (BWR).
• PWR containments are typically large (up to 7 times larger than a BWR) because the containment strategy during the leakage design basis accident entails providing adequate volume for the steam/air mixture that results from a loss-of-coolant-accident to expand into, limiting the ultimate pressure (driving force for leakage) reached in the containment building.
• F1 with an ABB Atom BWR 69 at 2928 MW thermal and 1010 MWe net was first connected to the grid on 5 June 1980, and commenced commercial operation on 10 December 1980.
• Above the critical point, steam and liquid become the same density and are indistinguishable, eliminating the need for pressurizers and steam generators (PWR), or jet/recirculation pumps, steam separators and dryers (BWR).
• The use of gas also removes the possibility of phase transition–induced explosions, such as when the water in a water-cooled reactor (PWR or BWR) flashes to steam upon overheating or depressurization.
• Hence, if MOX is used in a thermal reactor such as a boiling water reactor (BWR) or pressurized water reactor (PWR) then more americium can be expected to be found in the spent fuel than in that from a fast neutron reactor.
• It also uses natural circulation to drive coolant flow within the reactor pressure vessel (RPV); this results in fewer systems to maintain, and precludes significant BWR casualties such as recirculation line breaks.
• Water-cooled reactors utilising pressurised vessels, for example PWR and BWR reactors and their Generation III descendants, are unsuitable for online refuelling as the coolant is depressurised to allow for disassembly of the pressure vessel and therefore requires a major reactor shutdown.
• Reprocessing or recycling of the spent fuel from the most common class of civilian-electricity-generating or power reactor design, the LWR, (with examples being the PWR or BWR) recovers reactor grade plutonium (as defined since 1976), not fuel grade.
• BWR = Boiling water reactor, FBR = Fast breeder reactor, HTGR = High-temperature gas-cooled reactor, HWGCR = Heavy water gas-cooled reactor, PHWR = Pressurized heavy-water reactor, PWR = Pressurized water reactor, VVER = Water-water energetic reactor.
