Supercritical Water-Cooled Reactor (SCWR) Development through …
The supercritical water reactor (SCWR) is a concept Generation IV reactor, designed as a light water reactor (LWR) that operates at supercritical pressure (i.e. greater than 22.1 MPa). The term critical in this context refers to the critical point of water, and must not be confused with the concept of criticality of the nuclear … Visa mer The super-heated steam cooled reactors operating at subcritical-pressure were experimented with in both Soviet Union and in the United States as early as the 1950s and 1960s such as Beloyarsk Nuclear Power Station, … Visa mer Moderator-coolant The SCWR operates at supercritical pressure. The reactor outlet coolant is supercritical water. … Visa mer • Energy portal • Nuclear technology portal • Generation IV reactor • Breeder reactor • Reduced moderation water reactor, a concept that is in some ways similar and in others overlapping to the SCWR concept, and is under … Visa mer • Supercritical water has excellent heat transfer properties allowing a high-power density, a small core, and a small containment structure. Visa mer • Lower water inventory (due to compact primary loop) means less heat capacity to buffer transients and accidents (e.g., loss of feedwater flow or large break loss-of-coolant accident) resulting in accident and transient temperatures that are too high for conventional … Visa mer • Idaho National Laboratory Supercritical-Water-Cooled Reactor (SCWR) Fact Sheet • UW presentation: SCWR Fuel Rod Design Requirements (PowerPoint presentation). Visa mer WebbAn SCWR is a direct cycle nuclear system that operates under supercritical pressure conditions (~25 MPa). The coolant at the outlet of the reactor core has a temperature higher than 500 oC and goes directly to the turbine. With a thermal efficiency as high as 45%, the SCWR has much higher thermal efficiency than existing water- merrick bank credit card payment phone number
