(Closed) Unresolved Item (213/79-08-02):
The inspector verified that procedure SUR 5.1-75-C, " Power Range Channel Calibrations,"

(Closed) Unresolved Item (213/79-13-09):
The inspector verified that procedures E0P 3.1-5 and 3.1-7 have been revised to include curves for operators to use in verification that 50 degrees sub-cooling is being maintained.
(Closed) Unresolved Item (213/79-13-06):
The inspector verified that procedure SUR 5.1-17 data form had been modified to corr the normal data ranges.

Plant Tour The inspector conducted an inspection tour of accessible areas of the plant, including the Primary Auxiliary Building, Turbine Building, Switch Gear Room, Diesel Generator Rooms, HP Control Point, Cable Spreading Area, Auxiliary Feed Pump Area, and yard areas.
Details and findings are noted below.
a.
Monitoring Instrumentation and Annunciators Control Board monitoring instrumentation for power range nuclear instrument channels, pressurizer pressure and leval, main coolant system average temperature, delta T, and inlet temperature, refueling water storage tank level, axial flux offset, control rod position, and radiation process monitors were observed and compared with Technical Specification requirements several times during the inspection.
Control Board annunciators were observed for abnormal alarms each time the inspector was in the Control Room.
The inspector noted that annunciators indicated that all three pressurizer level channels had been placed in a tripped condition as required by IE Bu~lletin 79-06A, Revision 1.
No items of noncompliance were identified.
b.
Radiation Controls Radiation Controls established by the licensee, including posting and controls established for radiation /hich radiation areas, radiological surveys, condition of step-off pads, and the disposal of protective clothing were observed for confor-mance with the requirements of 10 CFR 20 and Technical Specifications.
,
No items of noncompliance were identified.
c.
Plant Housekeeping Plant housekeeping conditions, including general cleanliness and storage of materials to prevent fire hazards, were observed in all areas toured to verify conformance with QA 1.2-2.4,
" Housekeeping Requirements." No fire hazards were identified and general cleanliness was acceptable.
d.
Flpid Leaks and Piping Vibration
'
Systems and equipment in all areas toured were observed for the existence of fluid leaks and abnormal piping vibration.
{ (1 ?l
?
-4-No abnormal conditions were identified.
e.
Pipe Hangers / Seismic Restraints Spring pipe hangers and hydraulic shock suppressors installed on various piping systems throughout the plant were observed for proper installation, orientation, position, and fluid levels as applicable.
No discrepancies were identified.
f.
Control Room Manning Control Room manning was reviewed several times during the inspection to verify conformance with the requirements of Technical Specifications, 10 CFR 50.54k, and ADM 1.1-43, and IE Bulletin 79-06A (concerning dedicated auxiliary feedwater system operator).
No items of noncompliance were identified.
4.
In-office Review of Licensee Event Reports (lCd's)
The inspector reviewed LER's received in the RI office to verify that details of the event were clearly reported including the accuracy of the description of cause and adequacy of corrective action.
The inspector also determined whether further information was required from the licensee, whether generic implications were indicated, and whether the event warranted onsite followup.
The following LER's were reviewed.
79-02, One Channel Reactor Coolant Low Flow Trip Inoperable
--
- --
79-03, Diesel Fire Pump Inoperable 79-04, Primary Drain Cooler Discharge Line Leak
--
- --
79-05, Loop Fill Check Valve Failed Type C Leak Rate Test 79-06, Auxiliary Feedwater Pump--Low Discharge Flow
--
ETS 79-01, Fish Kill Overrun

ETS 79-02, Exceeded Rate of Change Limit for Circulating Water Discharge Temperature ETS 79-03, Greater Than 10 Curies Activity in RWST
--
iil'l 256
-5-ETS 79-04 Exceeded Circulating Water Chlorination Limit
--
Except'as noted below for those LER's selected for further review (denoted by *),
the inspector had no further questions in this area.
5.
Onsite Licensee Event Followup For those LER's selected for onsite followup, the inspector veri-fied that report.ing requirements of Technical Specifications and Regulatory Guide 1.16 had been met, that appropriate corrective action had been taken, that the event had been reviewed by the licensee in accordance with plant administrative procedures, and that continued operation of the facility was conducted within Technical Specification limits.
The followup included discussions with licensee personnel, review of PORC meeting minutes, and review of Plant Information Reports (PIR).
Details af findings are noted below.
79-03, Diesel Fire Pump Frozen Suction Line
--
The inspector reviewed a Plant Design Change Request (PDCR)
which had been submitted to add a line from the service water header to the fire pump suction to ensure flow and prevent freezing of stagnant water.
The LER did not identify actions to be taken to prevent recurrence.
The inspector informed the licensee that an update to the LER will be necessary when this PDCR is approved.
This item is unresolved pending review of the supplemental report and completion of correc-tive action.
(213/79-14-01)
79-05, Loop Fill Check Valve Failed Type C Leak Rate Test
--
The maintenance / test personnel performing the leak rate test on this valve did not determine an "as found" leak rate, but went ahead and repaired the valve when it was obvious the leakage was high.
A subsequent test was satisfactory.
The test personnel also failed to report the excessive leakage promptly to the Engineering Department.
The test coordinator is planning to submit changes to the leak rate test procedures to require recording "as found" data and informing the test coordinator promptly of any failures.
This item is unresolved pending inspector review of this completed corrective action.
(213/79-14-02)
ETS 79-04, Exceeded Circulating Water Chlorination Limit
--
Approximately 230 gallons of 12 percent sodium hypochlorite i1iy 251
.
.
-6-solution was discharged to the river's edge when the hypo-chlorination pump was improperly secured.
The inspector reviewed procedure NOP 2.20-4, "Startup and Operation of the Hypochlorite System," which specifies that the hypochlorite addition system will be secured by opening circuit No. 25 in electrical distribution panel LPW 1-1.
Had this been done, the pump and timer would have been deenergized and the inad-vertent discharge would not have occurred.
The licensee has reviewed the procedure requirements with the operators and has added a further precaution to the procedure to prevent recurrence.
A plant design change is also being investigated which would ensure that the pump relief line will return to the storage tank instead of discharging to the river.
The discharge of hypochlorite was in excess of that allowed by Technical Specification 2.3.1 and represents an infraction level item of noncompliance.
The completion of the design change will be reviewed in a subsequent inspection.
(213/79-14-03)
6.
In-Office Review of Monthly Operating Reports The inspector reviewed the licensee's Monthly Operating Reports for R vember 1978 - May 1979 in the RI Office to verify that reporting requirements were met.
No inadequacies were identified.
7.
Exit Interview The inspector held a management meeting at the conclusion of the inspection on June 22, 1979 (see Paragraph 1 for attendees) to discuss the scope and findings of the inspection as detailed in this report.
