INSPECTION PROCEDURE 61709 TOTAL POWER COEFFICIENT OF REACTIVITY AT PRESSURIZED WATER REACTORS

By 

Abstract

01.01 To verify that total power coefficient of reactivity measurements follow license commitments (e.g., ANSI Standards, Initial Core Load or Core Reload Analysis Reports) and are in compliance with Technical Specifications (TS). 01.02 To verify that total power coefficient measurements are conducted in accordance with licensee procedures, are correct, and are within their acceptance criteria. 61709-02 INSPECTION REQUIREMENTS 02.01 Review the licensee's procedures for measuring the total power coefficient of reactivity. Determine the adequacy of these procedures by comparing them to the license commitment documents of 01.01 above. 02.02 Review the retained records for recent total power coefficient measurements. If possible, observe actual measurements as they are conducted. Verify that: a. Prerequisites and initial conditions were met. b. Precautions and limitations were observed. c. Plant conditions were maintained as specified in the procedure. Verify that changes or relaxations of plant conditions were approved in accordance with TS and by the appropriate licensee personnel. Also verify that any other procedural deviations were similarly approved. d. Calculations of total power coefficient were performed correctly, including the application of necessary correction factors. Issue Date: 07/14/86- 1- 61709e. Values obtained for total power coefficient were within the acceptance criteria generated from analytical predictions of core reactivity. f. The licensee has properly resolved any discrepancies between actual measurements and the predicted coefficient values
