The NuScale is a light water reactor (LWR), with 235 U fuel enrichment of less than 5%. It has a two-year refueling period. [87] The modules, however, are exceptionally heavy, each weighing approximately 500 tons.
Illustration of a light water small modular nuclear reactor (SMR) The small modular reactor ( SMR ) is a class of small nuclear fission reactor , designed to be built in a factory, shipped to operational sites for installation and then used to power buildings or other commercial operations.
A diagram of a NuScale small modular reactor (SMR) NuScale reactors take 1% of the space of a conventional reactor and generate 77 MWe. [64] [65] [66] The design uses light water for cooling and power generation as in conventional nuclear plants. Water is heated by the nuclear core at the base of the reactor vessel.
The BWRX-300 is a smaller evolution of an earlier GE Hitachi reactor design, note the Economic Simplified Boiling Water Reactor (ESBWR) design and utilizing components of the operational Advanced boiling water reactor (ABWR) reactor. [1] Boiling water reactors are nuclear technology that use ordinary light water as a nuclear reactor coolant ...
RR is preparing a small modular reactor (SMR) design called the UK SMR, a close-coupled three-loop pressurized water reactor (PWR) design. [26] Power output was initially designed to be 440 MWe, and subsequently increased to 470 MWe which is above the usual range considered to be a SMR.
The light-water reactor (LWR) is a type of thermal-neutron reactor that uses normal water, as opposed to heavy water, as both its coolant and neutron moderator; furthermore a solid form of fissile elements is used as fuel. Thermal-neutron reactors are the most common type of nuclear reactor, and light-water reactors are the most common type of ...
The B&W mPower was a proposed small modular reactor designed by Babcock & Wilcox, and to be built by Generation mPower LLC, a joint venture of Babcock & Wilcox and Bechtel. It was a Generation III+ integral pressurized water reactor (light water reactor) concept. In March 2017, Bechtel withdrew from the joint venture and the project was ...
GE and Hitachi have developed the world’s safest Boiling Water Reactors (BWRs) over 60 years, with 40 reactors operating in 5 countries. BWRs and Pressurized Water Reactors (PWRs) both use light water as coolant and steam source, but BWRs generate steam directly in the reactor core, while PWRs use a secondary loop to produce steam.
