Contrary to the above:

a. The licensec perfonned an inadequate results evaluation for Technical Staff Surveillance Procedure TSS 15.6.51, "Zero Power Physics Measurements Following Refueling," performed for Unit 2 Cycle 9 on January 27-29, 1986, in that the independent review of the calculation of the critical operations restrictions to assure a negative moderator coefficient failed te detect that there were two errors present in the calculation. The failure to identify and correct the errors had minor safety significance.

b. Testing was not performed in accordance with written test procedures in that:

(1) Procedure steps were skipped (not signed nor performed before proceeding to the next step) during the performance of the following test procedure:
