SUMMARY

OF OPER.t'\\.TING EXPE~lCE MAY, 1980 Listed below in chronological sequence by unit is a sununary of operating experiences for this month which required load reductions or resulted in sign-ificant non-load related incidents. UNIT 1 Hay 1 May 10 May 11 Hay 12 ~1ay 13 Hay la May 20 This reporting period begins with the unit at cold shutdown for piping restraint modifications and turbine rotor inspection. Exceed 350°F/450 psig on primary system at 2215. The reactor was critical at 1547 and the generator was on-the-line at 2055. A reactor trip/turbine trip caused by feed flow/ steam flow mismatch in coincidence with a low level in "C" S/G occurred at 2106 while feeding S/G's. The reactor in manual was critical 2132 and the generator on the line at 2300. Com-menced power escalation. At 0700 reactor power was leveled off and held at 96% due to sodium carry over in the main steam system. At 1220 the control room operator placed the "B" mixed bed demineralizer in s'ervice. after flushing without having determined that the boron concen-tration (CB) of the effluent was equalized with the primary system CB. At this time the primary CB was 315 ppm and the demineralizer e~fluent CB was 1076 pp~. This inadvertant boron addition initiated a rapid power reduction from 95% to 80%. While stabili:dng plant parameters at 80% power the axial flux difference (AFD) deviatt:!d from the target band for greater than orie hour;.A power* i;eduction to 50% was commenced at 1250 and at 1325 the AFD returne~d to the target band. Power reached 50% at 1440. Conmenced power increase at 1325. Power reached loo;; at l845. At 1033, while attempting to return the "B" H. P. drain pump to service after maintenance, the pump discharge flange. developed a. severe leak. At 1148 a power reduction was corm;ienced to allow securing the "A" H. P. drain pump to facilitate isolation of the leaking pump discharge flange. The power reduction was stopped at 1215 at 92%. At 1632, after leaking flange was isolateJi and main-tenance personnel had tightened the flange bolts> the "A" H. P. clrain pUJ.11p_ was restarted and a power increase. was begun. Power reacr*ie.d 100% at* 1845. An inadvertant boration occurred at 1220 due to leakage of boric acid past MOV-1350. This resulted in a power decrease to 88%. A dilution and power increase was commenced and power reached 100% at 2030. At 1425 the chemist report the "A" boric C was 13.1%. This is greater than T.S. r~duction to hot shutdown began at 1438. BAST was determined to be 12.7% after the acid storage tank (BAST) limit of 13.0% and a power AT 1514 the C of the "A" addition of 2f 6 gallons of primary grade water and unit was returned to 100% power.

I. 10 .SUH!*lJ..RY OF OPERATING EXPERIEN. (continued) MAY, 1980 Listed below in chronological sequence by unit is a Slnnmary of operating experiences for this month which required load reductions o::- resulted in sign-ificant non-loacl related incidents. UNIT 1 1'1"..a.y 26 May 31 UNIT 2 May 1 May 3 May 9 May 26 May 31 Unit power was reduced to 96% at 1855 due to decreasing condenser vacuum. Unit power was returned to 100% at 2115 after condenser vacuum returned to normal. Power was reduced to 95% at 1835 to reduce sodium carryover in the main steam system. At 2240 power was increased to 97%. This report-ing period ends with the unit at reduced power due to sodium carry-over in the main steam system. This reporting period begins with the unit at refueling shutdm..'-n with the core loaded and the reactor vessel head removed. Reactor vessel head in place. Reactor vessel head bolted down. Type "A" test on conta.inment completed satisfactorily. This reporting period ends with the unit at cold shutdown with maintenance, piping restraint modifications and design changes continuing.

11 - AHEJ:ID.MENTS J'PFACILITY LICENSE OR TECHNICAL * *CI.FI CATIONS HAY, 1980 The Nuclear Regulatory CoIIIm.ission issued, on Hay 16, 1980, amendment. No. 58 to the Operating License for Surry Power Station Unit No. 2, which was designated as Technical Specification Change No.. 65. The change is a result of our request to revise the Unit 2 specifications to reflect a tube plugging limit to 3% for the new steam generators. Of significance are the following changes:

1.

2.

3.

The limit for the heat flu.~ hot channel factor, FQ (~),has been raised to 2.19. A curve of normalized operating envelope K(~), has been added for Unit 2. The limits for nuclear enthalpy rise hot c:b.annel factors, N kg~A and N I LOCA have been raised to 1.55 FliH FliH

Assm, and 1.476, respectively.

4.

Deletion of power distribution monitoring requirements.

12 - FACILITY CHA..NGES REOUIRIHG NRC APPROVAL MAY, 1980 Hone during this reporting period. FACILITY CHAHGE.S THAT DID NOT REQUIRE NRC APPROVAL The following facility changes were implemented during the month of }1ay: Design Changes

1.

DC/79-S37 ASCO Solenoid Valve Replacement This modification precipitated by IE Bulletin 79-01 provided for the replacement of solenoid valves presently installed with others which are enviroTu.~entally qualified. Suillillary of Safety Evaluation Unit 1 Since this design change merely replaces the pres~nt valves with identical ones having an environmental qualification, no new safety considerations have been surfaced beyond those previously addressed.*

D/C-79-58 Reactor Coolant System Subcooling Monitor System In an effort to weet requirements of THI 2 NUREG 0578 Section 2. L 3 b and subsequent NRC clarification, two subcooling meters have been in9talled on the main control board to provide indication of reactor coolant l!lE.rgin to saturation conditions. Suill!ilary of Safety Evaluation 2 This system will provide the operator with an indication of the reactor* coolant system margin to saturation conditions. It does not effect the operation of any safety-related equipment, therefore there are no safety probleras created with this modification.

D/C-80-35 Diverse Insolation Signals To Containment Trip Valves

• In response to section 2.1.4 of NUREG-0578 which addresses the possible consequences of depending solely on containment high pressure signals to isolate non-essential penetrations, diverse signals were supplied to non-essential containment trip valves.

Summary of Safety Evaluation This modification involved the deletion of outputs from the CLS system, replacing them with Safety Injection Signal outputs. This is the only change in the operation of the Engineered Safeguards System. Station Operating and Testing Procedures are to be updated to reflect this change. This design change improves the containment isolation system and has no effect on the operation of the other safety systems or safety related equipment.

• Indicates dates where station lT was less than 15.0°F across the station for sometime during the day.

The liT excursions were allowable under Technical Specifications 4.14.B.2. There were no reported instances of significant adverse environmental impact *. On May 28 or 29, 1980 a fish die-off which occurred was investigated. The die-off does not appear to be related to any temperature effect but a natural occurrance.

• FISH KILL I"NIJESTIGATION
• NAY, 1980 On the morning *af May 29, 1980, a commercial fisnenr.a.n reported seeing, "...*. thousands of dead menhaden floating out of the discharge canal".

He had observed the fish while tending trot lines located at the Surry Power Station discharge groin sometime during the night of Hay 28-29, 1980. An investigation was initiated innnediately to determine the validity and extent of the reported fish kill. Intake and discharge temperatures were determined for the night in question, beach and water surveys were conducted, and individual_ specimens were e..~amined. A total of 65 dead menhaden were located in an area from 100 yards upstream from the discharge groin to a point one mile downstream. Of this total 34 were found in the slack water inside the groin and 31 were floating in the water near shore throughout the remainder of the area. None of these fish were found on the beach which seems to indicate the fish had died recently. Also, none of the fish were in the flowing water of the discharge canal indicating the reported fish kill was not occurring at the time the surveys were conducted. Menhaden (Brevoortia tyrannus) was the only species observed. All specimens ranged in length from lOOram to 140mm which indicates they were age I fish.. None of the 20.specimens examined showed any signs of mechanical damage which rules out *the po"er station screens and culling by fishermen as the cause of death. Observations were made periodically throughout the evening of

Hay 29, 2.nd the early morning hours of May 30, 1980, to watch for any reoccurrc:nce of the reported fish kill.

Only two dead fish were observed during the entire night even though the b.T0 across the station and the maximum. water temperature were approximately the same as when the dead fish were observed by the fisherman. Observations during the hours of darkness revealed a possible explanation for the discrepancy between the fisherman's report of "thousands" of dead fish and the small numbers found in.our surveys. Fo2.m generated in the turbulence of the Unit 1 discharge breaks into small cohesive patches about the size of the dead menhaden observed. With the use of artificial lighting 2.t night it is extremely dHficult to d.iffere~1tiate between the foam. and dead fish without. moving to within 2. couple feet of the object observed. When -the light was cast across the canal it appeared as if a fish kill was in progress. Additional beach surveys were conducted on May 30, and June 2, 1980~ but no dead fish were found. Conclusions Evidence indicates a minor Menhaden die-off occurred in the station discharge canal during the evening of May 28 or. the morning of May 29, 1980.

~ 20 - FISH KILL INVESTIGATION (continu~d) A die-off is indicated as opposed to a fish kill directly related to the operational e£f ects of Surry Power Station. The deaci fish were exclusively age I menhaden and did not include any age 0 menhaden* which are extremely abundant in the river. This pattern has been observed in other natural die-offs of menhaden which have occurred frequently else-where in the river. Also, live menhaden were observed in the discharge canal in very large numbers after the reported fish kill. Operational and water temperature conditions during these observations were almost identical to those occurring during the period when the fish kil],. was reported to have occurred. The die-off can be termed minor relative to the large natural die-off s observed elsewhere in the river. A die-off on June 14, 1979 inves-tigated by this office and the State Water Control Board found several thousand fish per mile which is much larger than the 65 fish per mile . found in this investigation. Fish from the June, 1979 die-off were found on several miles of beach whereas this investigation did not find any fish beyond one mile downstream from the groin.
