Containment Building - Types - Pressurized Water Reactors
... PWR containments are typically large (up to 10 times larger than a BWR) because the containment strategy during the leakage design basis accident entails providing adequate volume for the steam/air ... As reactor designs have evolved, many nearly spherical containment designs for PWRs have also been constructed ... Most current PWR designs involve some combination of the two, with a cylindrical lower part and a half-spherical top ...
Pressurized Water Reactor
... Pressurized water reactors (PWRs) constitute the large majority of all Western nuclear power plants and are one of three types of light water reactor (LWR), the other types being boiling water reactors (BWRs ... In a PWR, the primary coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy generated by the fission of atoms ... PWRs were originally designed to serve as nuclear propulsion for nuclear submarines and were used in the original design of the second commercial power ...

PWRs were originally designed to serve as nuclear propulsion for nuclear submarines and were used in the original design of the second commercial power plant at Shippingport Atomic Power Station ...
Boiling Water Reactors - Advantages and Disadvantages - Advantages
... times atmospheric pressure) compared to a PWR (about 158 times atmospheric pressure) ... Pressure vessel is subject to significantly less irradiation compared to a PWR, and so does not become as brittle with age ... causing loss of coolant compared to a PWR, and lower risk of core damage should such a rupture occur ...
Alvin M. Weinberg - Work At Oak Ridge - Weinberg's Firing Impacts MSR and Thorium Based Nuclear Fuel Research
... as a nuclear fuel in other reactors such as PWRs, so Weinberg's firing reduced thorium's nuclear fuel research ... of U-233 fissile from thorium in 1982 in a Pressurized Water Reactor (PWR), no further research or development would be done until the 1990s ... LWBR's Seed and Blanket Unit (SBU) based re-coring of existing PWRs with fuels consisting of mainly thorium instead of uranium-238 ...
