J 3.0 Preoperational Test (POT) Program 3.1 POT Program Review References i
(1) Startup Manual (2) FSAR, Chapter 14 (3) Regulatory Guide 1.68, Revision 2, " Initial Test Programs for Water Cooled Nuclear Power Plants" (4) NRC Inspection Report No. 50-443/83-16, issued November 15, 1983 i
Scope A review of the preoperational test program was conducted to verify adherence to the requirements and commitments of documents (2) and (3) referenced above.
Discussion
'
A general review was made of the administrative procedures, Test Program Instructions (TPIs), which are a part of the Startup
Manual. These TPIs were compared with the commitments made in the FSAR, Chapter 14 (Ref. 2) and the requirements of the Regulatory Guide 1.68 (Ref. 3) to verify that the administrative measures have been established to control the conduct of preoperational testing including:
(1) Preoperational Test Program description; (2) A method to control turnover of systems from the constructor to
,
I the Startup department (STO) and, subsequently, from STD to the i
operations department; (3) Preoperational Tests for the plant systems listed in Regulatory i
Guide 1.68; I
(4) A formal method to control preoperational test procedure format, content, review and approval, and changes to procedures; (5) A formal method to control interruption of testing and retest
,
l requirements; i
l (6) A formal method to control calibration and issuance of measuring l
and test equipment; and i
(7) A method to control lifted lead, jumpers and safety tagging.

In view of the status of the preoperational testing (post HFT),
special attention was paid to items 4 and 5.
The following areas of concern resulted from the review of these items:
a.
Retesting for phase 1 and 3 POTS. Who decides whether the retest will be a phase 1, 2 or 3 test?
b.
Retest records review and approval, c.
Retest record retention and retrieval.
d.
Prioritization of incomplete items by startup milestone.
These areas of concern were discussed with the licensee. With reference to a.above, the Joint Test Group (JTG) will review and approve the retest procedure selected by the responsible startup engineer, who will base his selection on the impact which the test deficiency had on the preoperational test.
<
With reference to b.and c.above, retest records will be reviewed and approved by the JTG. These test records will be added to the test package for the pertinent completed test.
With reference to d.above, the licensee indicated that some prioritization has been done already.
In view of the small number of incomplete items generated to date, prioritization is not con-sidered to be a significant problem.
t Findings Within the scope of this inspection, no violations were observed.
3.2 Preoperational and Acceptance Test Results Evaluation Review Scope The completed test procedures listed in Attachment A were reviewed during this inspection to verify that adequate testing had been conducted to satisfy regulatory guidance, licensee commitments and FSAR requirements and to verify that uniform criteria are being applied for evaluation of completed test results in order to assure technical and administrative adequacy.
The inspector reviewed the test results and verified the licensee's evaluation of test results by review of test changes, test exceptions, test deficiencies, "As-Run" copy of test procedure, acceptance criteria, performance verification, recording conduct of test, QC
!
inspection records, restoration of system to normal after test, independent verification of critical steps or parameters, identifi-cation of personnel conducting and evaluating test data, and verification that the test results have been approved.

Discussion PT(I)-9, Revision 2, "ECCS HOT Functional Test." Check valve
leakage for many valves initially was found to be in excess of the acceptable values shown in the procedure. Additional flush-ing and cleaning of the associated piping brought these leakages back within the acceptable values. The basis for the acceptance criteria, as shown in the procedure, was not provided in same.
The licensee stated that the numbers in the procedure are based
.on 10 cc/hr per inch of nominal pipe diameter. The source of this number was not known nor was it shown as a reference in the procedure. The inspector will follow up on this item in a future inspection.
The inspector noted that, in F.C. #5, the minimum recirculation flow rate of the pump had been cut back from 90 to 40 gpm. A reason for this change was not supplied in FC #5. The licensee said that the 90 gpm was intended for two pumps. Since they were only using one pump, the minimum flow could be cut back to 45 gpm (or as low as 40.5 gpm with the -4.5 gpm tolerance)
without overheating the pump. The actual value found in the field was 42 gpm which is above the minimum acceptable value of 40.5 gpm.
The inspector had no further questions on this procedure.
Findings No discrepancies or violations were identified during the above review. There were, however, several open test exceptions that require licensee corrective action to resolve. These test excep-tions were assigned to the incomplete items list (IIL) or, in certain cases, a work request (WR) was issued for tracking purposes. The following open test exceptions, identified in previous NRC reports, are being consolidated into one unresolved item (443/86-01-01) and unresolved items 443/85-26-01 and 443/85-30-02 are closed.
The following IIL numbers correspond to open test exceptions and, collectively, constitute unresolved item 443/86-01-01.

J 6.0 Plant Tours The inspector, accompanied by the Resident Inspector, made a tour of the facility. Areas toured included the containment, the fuel storage build-a
'
ing, control building, the primary auxiliary building, emergency feedwater pump house, the diesel generator building, turbine building and the heater bay. The inspector observed work in progress, housekeeping, cleanliness control, and status of construction activities. The following observations were made:
'
The emergency diesel generators (EDGs), Colt-Pielstick units, had
good piping layout for fuel oil and lube oil, and fire secure mount-ing of fuel oil filters. The brush holders support bars, which are
identical to the original bars of the Millstone 3 EDGs, had not been
replaced yet but were scheduled to be in the near future.
Good main control board panel layout with simple and effective
mimics.
,
Heavy dust layers on cables in cable trays of the Turbine Building.
- Crane layout in Fuel Building to meet heavy load criteria.
- No violations were identified.
7.0 Unresolved Items Unresolved items are matters about which more information is required in order to determine whether they are acceptable, an item of noncompliance or a deviation. An unresolved item concerning open test exceptions is
discussed in Paragraph 3.2 of this report.
8.0 Exit Interview At the conclusion of the site inspection on January 10, 1986, an exit interview was conducted with the licensee's senior site representatives (denoted in Section 1). The findings were identified and previous inspection items were discussed.
At no time during this inspection was written material provided to the licensee by the inspector.
Based on the NRC Region I review of this j
report and discussions held with licensee representatives during this inspection, it was determined that this report does not contain informa-tion subject to 10 CFR 2.790 restrictions.
