Preoperational Test Procedure Review The inspector reviewed the following preoperational test procedures:
ED-1 D. C. Distribution System
.
EV-1 A. C. Distribution System
.
CS-3 RCP Standpipe Flow Verification
.
RC-01-H-1 Reactor Coolant System Cold Hydro
.
The procedures were reviewed to ensure they were technically adequate and
'to ensure they were consistent with the commitments made in Chapter 14 of the FSAR and with Regulatory Guide 1.68.
The inspector had the following comments concerning the tests:
a.
ED-1 did not include the Load Bank ammeter on the list of instruments to be calibrated before and after the test. The procedure also did not address the possibility of changing pilot cells during the course of the battery discharge.
3oth of these items were corrected by issuing a minor change to the test procedure.
b.
Step 6.5.30 of EV-1 should have read "Open breaker 5901/31" instead of
"Open breaker 5901/27". EV-1 did not contain a list. of installed instrumentation to be used to provide acceptance data in the prerequi-site section of the test as required by the Start Up Manual. EV-1 also did not indicate in the Data Requirements section of the test a signoff to indicate that the installed instrumentation had a calibra-tion check done on it after the completion of the test. All comments concerning EV-1 were resolved by issuance of minor change to the test.
Step 5.19 of RC-01-H-1 indicated that all temporary equipment and c.
scaling changes must be tagged or marked to identify service. The inspector noted that the tags were not being installed, however, the procedure addressed the installation and removal of all temporary equipment mentioned in the procedure. The procedure was changed to indicate a tag would be installed on all temporary equipment not specifically mentioned in the procedure.
Step 6.91 stated, " Remove the jumpers and install the spool pieces removed in Step 3.2.17." This step should have read " Remove.
.
.
.
in Step 3.2.23".
Step 7 of the Attachment VIII to the procedure stated, "After ten (10)
minutes, lower the system pressure as read on the test gage to the pressure specified in Step 3.1".
This step should read, "After ten (10) minutes, lower the system pressure as read on the test gage to
_
the pressure specified in Step 6.59".
All of the above comments on RC-01-H-1 have been corrected.

Preoperational Test Witnessing The inspector witnessed portions of the following preoperational tests:
ED-1 D. C. Distribution System
.
EV-1 A. C. Distribution System
.
CS-3 RCP Standpipe Flow Verification
.
RC-01-H-1 Reactor Coolant Syr. tem Cold Hydro
.
The inspector verified the tests were being p3rformed in accordance with approved procedures and verified the acceptability of the test results.
Specifically, the inspector verified that prerequisites were met, the procedure was being followed and data recorded as required. Findings were acceptable with the following exceptions:
.ED-1 called for a discharge rate of 273 amps on the battery to verify a.
a total amp hour capacity of 819 amps for 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br />. The meter being used w s scaled in 20 amp increments and the ability to distinguish between 270 and 275 amps was questioned by the inspector. The licensee acknowledged the inspector's comment and agreed to look into the matter in future preoperational tests.
.
b.
Step 5.3 of RC-01-H-1, (Cold Hydro) states, "Do not exceed 150 F during heatup operations for this hydro test as read on loop RTD's in service". Step 5.10 states, "Do not exceed a RCS heatup rate of 50 F/hr". The inspector noted that on November 2, 1979. while heating up the RCS, a heatup rate of between 55 F-60 F/hr over a one hour period was obtained. The inspector also noted that one loop reached a temperature of approximately 155*F during the heatup. Criterion V of Appendix B to 10CFR50 states that " Activities affecting quality shall be prescribed in documented instructions, procedures, or drawings of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures or drawings". The Construction Quality Assurance Plan Section 4.6, states in part that "a comprehensive preoperational test program will be conducted... system-atic planning and audit as well as the use of documented procedures provide the necessary quality assurance." The excessive heatup rate and temperature appears to be in noncompliance with this requirement (79-37-01).

Independent Inspection Effort-FSAR Review The inspector reviewed portions of the FSAR in conjunction with the preop-e, rational tests to verify the commitments made in the FSAR. Findings were acceptable with the following exceptions:
a.
Section 8.3.2.1.5.2 of the FSAR states that, " Main breakers, as shown on Figures 8.3-1, 8.3-2 and 8.3-4 are equipped with auxiliary switches to sound an alarm and operate indicator lights in the control room".
The inspector noted that not all the breakers on Figures 8.3-1, 8.3-2 and 8.3-4 which are supposed to indicate or alarm in the control room have indicator lights or alarms installed. This will remain open (79-37-02) pending evaluation by the licensee.

The same section of the FSAR states that an alarm actuates if battery voltage falls slightly below float voltage. The inspector noted that there is no alarm of this type presently in the control room. This item will remain open (7-38-02) pending evaluation by the licensee.
b.
Section 3.1.2.2 of the FSAR states that "Part length control rods provide the capability of attenuating axial oscillations" Part length rods will not be used. This item will remain open (79-38-04) pending FSAR amendment.
8.
Independent Inspection Effort - Operational Quality Assurance Manual Review The inspector reviewed positions of the Operational Quality Assurance Manual QAM) and had the following comments:
Section 4.3 of the 0QAM states, "the requirements for observance of a.
procedural instruction by plant personnel and this use of procedures is mandatory and shall be prescribed in an Administrative Procedure".
The inspector noted that no Administrative Procedure addresses this issue and operating procedures and Phase II, startup procedures, are being used. This item will remain open (79-37-05) pending licensee review.
9.
Plant Tour The inspector toured the plant at various times to observe construction activities, housekeeping, maintenance, equipment preservation and logbooks.
Findings were acceptable with the exception of the following:
The Battery Charger Technical Manual, for the SCI Battery Charger a.
Model BCS 12300 states that " adequate ventilation should be provided by allowing at least six inches of space behind the charger, at least two feet in front of the charger and at least one foot above the top of the charger". The safety related battery chargers are located flush against the wall and do not provide the required six inches for proper ventilation. This item will remain open (79-37-06) pending Jicensee review.
10.
NRR Site Visit The inspector participated in a visit to the site by NRR to gather informa-tion for a piping audit calculation to be performed by Pacific Northwest Laboratory. The visit took place on October 31, 1979 and lasted one day.
