Prairie Island Startup Physics Testing Report Unit 1 Cycle 17
1.0 INTRODUCTION
Forty-eight reload fuel assemblies manufactured by Westinghouse were installed in the Prairie Island Unit 1 reactor during the June 1994 refueling outage. The core design uses the VANTAGE + fuel assemblies enriched to 4.95 w/o U235. For peaking and ITC control this design uses 432 - 6 w/o gadolinium doped pins.
2.0 STARTUP PHYSICS TESTING This report provides test results for the tests conducted during the startup of the Unit 1 Prairie Island Nuclear Generating Plant. The procedures used in the startup test program were the must recent revision reviewed by the Plant Operations Committee. The tests performed included:
a) Zero Power Isothermal Temperature Coefficient b) Control Banks' Worth c) Critical Boron Concentration d) Power Distribution Measurements Table 1 summarizes the data for each test performed.
