Unresolved Items Unresolved items were not identified during this inspection.
5.
Preoperational Test Witnessing The inspector witnessed the verification of plant initial condition, including establishing of minimum flows for the service water system loads, for preoperational test TP/1/A/1200/01.
Specific loads were:
(a) Waste Gas Compressor heat exchangers (b) Sample heat exchangers (c) Waste Evaporator condenser and cooler
.
%
-2-s (d) Recycle Evaporator condenser and cooler The inspector also witnessed the licensee trouble-shoot electrical problems encountered in preparation for Diesel Generator lA Load Sequencer Functional Test, TP/1/A/1350/08/A. Specifically, the time delay had been set on three relays in accordance with an instrumentation procedure, yet when checked in accordance with the test procedure were found to be out of specification.
Investigation by the licensee determined that the relays' time delay was in specification but that the onset of the time interval was effected by the length of time that a "Special Test Reset" button was depressed. Once this was identified the licensee corrected his test procedure to preclude this effect and was in the process of correcting problems with local diesel generator instruments before resuming the test.
6.
Unit 2 Preoperational Tests The licensee notified the inspector that he did not intend to perform a full pressure blow-down test of the upper head injection system on unit 2.
The basis for this decision was a Westinghouse letter (OBP-280, DUKE-4952)
from R. S. Howard to S. K. Blockley (Duke) dated 11/5/79.
In this letter Westinghouse stated that based on their analysis of the Unit 1 blowdown data, that a normal pressure blowdown of the Unit 2 Upper Head injection system would not be necessary and provided revised acceptance criteria for the low (90 PSIG) pressure blowdown. The letter states that meeting the revised acceptance criteria would insure that the final volume of water delivered to the reactor vessel during a normal blowdown would be within the band used in the ECCS analysis.
The licensee stated that an ammendment to the FSAR in sections 6.3 and 14.1 would be proposed identifying that a normal pressure UHI system blowdown would not be performed on unit 2.
The inspector acknowledged receipt of a copy of the Westinghouse letter and a memorandum on the proposed FSAR changes. The licensee though still must address how the isolation valves will be tested against maximum differential pressure as required by Reg Guide 1.79.
The resolution of the test program for the UHI system will be followed as Open Item 79-39-01.
7.
Unit 1 Ice Loading The inspector monitored the Unit 1 ice loading activities in progress which consisted of clearing ice chips and debris from around the baskets which had been already loaded. Repairing the conveyor feed belt between the ice machine storage hopper and the ice chopper / blower assembly had delayed resumption of loading operations. Recalibration of the spring scale and the dillon load cell had interrupted ice basket weighing.
8.
Site Personnel Reorganization The licensee informed the inspector of the following personnel and organiza-tional changes at McGuire Nuclear Station:
An Onshift Radiological / Chemistry group has been organized to handle waste processing activities. They will report to the station chemist and organiza-
