Experimental Program for the Fast Breeder Blanket Facility, FBBF

摘要

The work performed in the reporting period was primarily concerned with the development of the experimental program (Task A) and with the pre-analysis of future loadings and the impact upon the permanent loading of the two converter regions, which contain 4.8 percent enriched UO sub 2 rods. It appears necessary that a neutron poison (B sub 4 C) be placed in the converter (transformer) regions in order to hold, also for future loadings, the k/sub eff/ of a hypothetically flooded FBBF well below 1. Since it is planned to use the same welded converter regions for all experiments, the required B sub 4 C loading needs to be determined prior to the first blanket loading. Further the equipment needs have been identified (Task D), the exp 252 Cf-source has been requested on a loan basis (Task E). First discussions with ANL on blanket experiments have been initiated.
