ZPPR Plates Structural Performance in HAC

Zero Power Physics Reactor (ZPPR) are a radioactive material form used to study the physics of fast neutron spectrum reactors and for criticality studies of mixed uranium/plutonium nuclear processing system. Any fast spectrum system could be studied in ZPPR with a full-sized simulation that faithfully reproduced both the compositions and the geometry of the system under study. To ship the ZPPR plates in a packaging that is compliant with Title 10 of the Code of Federal Regulations Part 71 (10 CFR 71) the performance of the Plates to the Hypothetical Accident Condition tests specified in Section 73 of 10 CFR 71. Once the performance of the ZPPR Plates was established, any additional protection needed to meet the 10 CFR 71.73 criteria could be designed into the packaging. The performance of the ZPPR Plates to the HAC Tests is discussed in this paper.
