l l Prairie Island i Startup Physics Test Report Unit 2 Cycle 16

1.0 INTRODUCTION

l The Prairie Island Unit 2 reactor had 48 reload fuel assemblies manufactured by Westinghouse installed during the November 1993 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 336 pins with 6 w/o gadolinium and 64 pins with 8 w/o gadolinium. The 8 w/o gadolinium pins are located in 8 demonstration assemblies.

j 2.0 STARTUP PHYSICS TESTING - INTRODUCTION:

l This report provides test results for the tests conducted during the startup of Prairie Island Nuclear Generating Plant, Unit 2. The procedures used in the startup test program were the most recent revision reviewed by the Plant operations Committee. The tests performed included the following:

(a) Zero Power Isothermal Temperature Coefficient (b) Control Banks' Worth (c) Critical Boron Concentration (d) Power Distribution Measurement j l

3.0 STARTUP PHYSICS TESTING - RESULTS:

Table 1 summarizes the following data for each test performed.

(a) Test

! (b) Procedure / Effective Revision (c) Parameter (d) Measured Value (e) Acceptance Criteria 4.0

SUMMARY

The data in Table 1 shows agreement with the acceptance criteria.
