- Summary
-
In addition to the nine cross-shaped control rods which pass through vertical guide channels in the core, a secondary non-inherent safety mechanism in the form of a pressurized concentrated boric acid solution can reduce the reactivity by at least 12.5% k in about 20 seconds. With regard to inherent safety, the EBWR has a much stronger metal temperature coefficient, but a considerably weaker steam formation shutdown mechanism, than the Borax reactors. Estimates were made of the amount of reactivity which can be controlled by steam formation in the EBWR. The maximum heat flux in EBWR is believed to be below the burnout point by at least a factor of 4 to 5, based on laboratory tests with electrically heated plates. The EBWR is surrounded by a gas-tight steel building having a volume of about 400,000 ft/sup 3/ and designed to withstand an internal pressure of 15 psig. A 15,000-gal reservoir of water is suspended from the dome of the building for emergency cooling. The gas-tight building could easily withstand the internal pressure resulting from blow-down of the pressurized water in the reactor. The major design and operating features of the EBWR facility are summarized.
