Although the BWRs that were built in the 1980s were advancements on the simple foundations of ones built in the 1940s, the vigorous transcriptions were the culprit on the flaws within the main designs. The newer ESBWRs apply a much passive system inside and outback(a) of the consequence. Instead of using pumps to implement flow within the core, the ESBWR system uses natural circulation. This impart show in the design parameters of each system on the advancements of the BWR design.
Although the ESBWR uses none of the active systems that the antecedent design entails, the power production from the natural circulation, gravity, evaporation, and condensation that the march on design incorporates is much greater than the previous design. The previous designs production of its components fit to a build-as-you-go concept; this set up cause a longer production process, plus more of a chance that things going wrong with this production process. completely the components of the ESBWR system are produced prior to putting the pieces together; therefore, this will cut production costs and time spent on the project.
As far as enrichment of fuel, the old and new designs do not differ much at all. For the 1980s design, it has a fuel enrichment of 2.5-4.5% UO2.
With the ESWBR, for a 24-month cycle, it has a UO2 enrichment of 4.2%. Due to the similar enrichment of the fuels, the core and plant design plays a big part in power production. Due to the ultimate passive design of the ESBWR, less(prenominal) intrusion on the natural circulation, gravity, and condensation within the outgrowth of the plant leads to more efficient power production.
