Licensee Action on Previous Inspection Findings (Closed) Unresolved item 320/76-17-04. The licensee has addressed the method of identification of the minimum flush temperatures.
The individual flushes requiring monitored temperatures to be maintained, will be identified to Metropolitan Edison Company Operations Department (Letter RT/sk 12/9/76). This item is re-solved.
(Closed) Unresolved item 320/76-17-12. The " Maintenance Exercise" position on Diesel Panel (Control Room) actuates an alarm indicator, noting diesel out of service.
When diesel is not operational, the limiting conditions of the proposed T.S. 3/4, 8.1 requires L.C.O.
action. This item is resolved.

TP 202/7 Makeup and Purification Preoperational Test Procedure Review
.
References:
(a) Regulatory Guide 1.79 Rev.1, Preoperational Testing of ECCS for P.W.R.
(b) TMl-2 FSAR(1) chapter 6.3.4 (2) Supplement 3.4.13/14.1 item 10 (c) Regulatory Guide 1.68, Initial Test Program for Water Cooled Reactor Power Plants.
Review of the approved procedure included: format, flow rates under designed pressure, runout pump flows, valve timing, instrumentation and piping vibration.
The review of procedure noted concerns in area of cold leg injec-tion pump, suction changeover, integrated system testing, hot injection testing, alternate power sources and maximum test pressure of demonstration runs for makeup pumps.
The ECCS requirements in the high pressure injection area are addressed by the licensee in the following procedures and documents:
Boron precipitation after loss of coolant - page 6-11 Safety a.
Evaluation Report; b.
H.P. pump suction for long term cooling - T.P. 20?/3;
.
c.
Intergrated Testing - T.P. 600/21; and, d.
Hot high pressure safety injection (check valve operabil.ity) -
T.P. 600/4.
'
One area of concern was the required discharge pressure versus flow of make up pumps. The licensee has written a " test exception" which will record additional data at a makeup flow of > 500 gpm, R.C. pressure of > 600 psig and time to achieve these parameters.
The inspector has no further questions on this procedure. This item is closed.

Observation of Testing T.P. 202/3 Makeup 33,d Purification Functional Test On May 24,1977 the inspector witnessed the start up of MVP-lC (make up pump-lC) and MUP-1B.
Objectives of this portion of the test were to establish head flow curves for the pumps.
(Used for high pressure injection).
Test Results The MUP-lC pump run was aborted after approximately ten minutes into the test due to high thrust bearing temperatures.
The MUP-1-B pump run was aborted after approximately forty minutes due to a failure to locate an inadvertant flow path to RCS.
Pressurizer level increased from 90" to 345" within 30 minutes with an accompanied rise in pressure from 40 to 120 psig.
The licensee is presently pursuing problem areas.
Crew Performc1ce
'
The licensee's test and operational personnel were )bserved during the performance of the test for the following attributes:
Proper revision e* the test procedure available to all test members; Sufficient personnel to conduct the test; Prerequisites adhered to for testing in progress; and, Special test equ.ipment in use, for example, correctly calibrated digital hand held pyrometer, to monitor pump bearing caps.
The test was performed as required by the procedure and was aborted for reason stated under Test Results.
The observation by the inspector for the work accomplished did not identify any inadequacies.
This item ir closed.

Pressurizer Relief Valves The licensee's relief valve vendor was on site and is presently disassembling valves for inspection.
Testing of valves has not been completed. A review of the maintenance work request will be made at conclusion of the job order.
This is an inspector followup item (IFI-77-18-01).
6.
Test Results Evaluation and Verification The inspector reviewed the test results of the following procedures:
T.P. 200fi Reactor Internal Vent Valves Inspection Test; T.P. 268/3 Secondary Service River Water System Functional Test; T.P. 235/6 Control Building Area Sump Test.
The inspector's evaluation of the test results of procedure T.P.
a.
200/1 Reactor Internal Vent Valves Inspection Test includes the following parameters:
(1) Review of all test exceptions; (2) No test deficiencies were identified by the licensee; (3)
Review of the " cognizant engineering review" which was accomplished on May 9,1977, and (4) Test results were approved by licensee on May 19, 1977.
(TWG approval).
.
No inadequacies were identified by the inspector. This item is closed.

R. C. System Hydrostatic Test The inspector reviewed with startup and Q.C. personnel the status of items that have to be accomplished prior to the R. C. System hydro. The test plan was reviewed in the area of hydro.
The tentative test schedule calls for conduct of test on June 1,1977.
8.
Tour of Working Areas Prior to the entrance interview the inspector made an urannounced tour of Primary Auxiliary Building, Containment, Control Room cnd Diesel Generator Rooms. No inadequacies were identified.
9.
Exit Interview (
The inspector met with licensee representatives (See Detail 1 for attendees) at the conclusion of the inspection on May 24, 1977.
The inspector summarized the scope and the findings of the inspection as described in paragraphs 2 through 8.
