Unusual occurrence: l i Coincident with a plant shutdown on January 28, 1972, large numbers of ' dead fish were found in coves off Barnegat Bay between the discharge canal and the inlet canal. Newspaper articles attributed the fish kill to.the sudden cooling of the water in the discharge canal.

Mr. Ed Growney, Engineer Mr. Don Kaulbach, Radiation Protection Supervisor Mr. Charles Amato, Nuclear Engineer, N. J.

An exit interview was held with Mr McCluskey on Feburary 7,1972.
The inspector stated that there appeared to be a "cause and effect" rela-tionship between the fish kill and the plant shutdown which lowered the water temperature in the outlet canal. Mr. McCluskey stated that before , ' talking to Dr. Wurtz, he would have agreed to this statement, however, Dr. Wurtz stated that as a result of the decrease in bay temperature before the plant shutdown, the water temperature was already down e.o the thresh-hold temperature for survival for these warm water fish. As such, it was his opinion that some of the fish would have died as a result of the natural drop in water temperature.

- Details ~of: Subjects Discussed in Section I
- 1., " Plant records show that a "five recirculation pump trip test" was
. conducted at 10:42 p.m. on January 27, 1972. Reactor power dropped from 1890 MWt to 825 MWt when~the pumps were tripped, and returned to 1325 MWt when the recirculation pumps were restarted. ' Following
- completion of the test, a planned power reduction began, and the
, generator was-taken off line at 4:30 a.m. ' on January 128,1972.
Following completion of the planned maintenance work, the approach to critical began 'at 1:50 p.m., Jantary 30;.1972. and the generator was-placedLon'11ne at 4:28 a.m., January 31, 1972. ~Pcwer was in-creased in steps to 1840 MWt at 1:00 p.m., February 2,1972. The
- prime purpose of the outage was to identify and repair primary system
> leaks in the'drywell. -(The unidentified leakage rate.vas 4 gpm.
unidentified leakage to 5 gpm.)
-Technical Specification'11mit - 2. L Fish ' Kill in Barnegat Bay According to Mr. McCluskey, the first reports of dead fish were received at the. plant on January 29, 1972. The dead fish were re-ported,between the plant inlet and outlet canals.
Mr. Ross reported that he went to the location where the dead fish were reported. He stated that he estimated the number of dead fish was in the " hundreds".
In one newspaper. article in the Trenton Sunday Times Advertiser, Mr.
Hamer, Marine Biologist, State of New Jersey, was reported to have-estimated there were 200,000_ dead fish, and that 99.9% of these fish were menhaden. Mr. McCluskey stated that by January 31, 1972, most of these fish had been eaten by sea gulls. Jersey Central's - minutes 'of a meeting on February 1,1972 to discuss the fish kill problem' with local officials indicated that the Township officials agreed cleanup of dead fish would not be a problem. The meeting was attended by representatives from Jersey Central and Ocean and Lacey Townships.

Release Records Radioactive release records and chemical release records were re-viewed. - Radioactive release records showed that one batch was released (1800 gallons) on January 28 and two batches (16,000 and 2,000) were released on January 29, 1972. A gamma spectrum was run - onLeach batch prior to each release and each batch met applicable release ILnits. The release rate was controlled to meet the limits for unidentified releases even though an isotopic analysis was ~ performed. This is the normal method used by Oyster Creek.

-4-Records show that two. batches (5,200 gallons each) of chromated . water (K Cr04) were _ transferred to Sumco, Inc. (Caldwell, N. J.)-
tank trucks for disposal. These transfers were made on February 3 and April 8, 1971. This water was removed from the torus. These were the only chemicals that.the records indicate had been removed from the-plant during CY 1971 and CY 1972 through February 7,1972.
In response to specific questions asked of Mr. Carroll by the inspector * regarding chlorination of condenser cooling water, the following information was obtained. The maximum rate used is 4000 pounds / day (in' summer). The rate currently in use is 1000 pounds / day. The rate _is chosen to give a residual of 0.5 - 1 ppm at the condenser outlet. Seven streams are chlorinated for 1/2 hour each and the system stops for 1/2 hour (i.e., each stream is chlorinated for 1/2 hour _ every 4 hours). The last analysis for chlorine at the l condenser outlet showed 1.5 ppm on June 17, 1971 with a 4000 pound / day feed. The rate of chloration was reduced from 4000 pounds / day to 1000 pounds / day on December 1, 1971.
Cooling Water Temperature i Temperature charts were reviewed showing the condenser inlet and I outlet temperatures and the temperature of the water in the discharge canal at the point where the outlet water leaves Jersey Central property (the railroad bridge). The condenser temperature chart showed that the inlet coo 1L.g water temperature dropped from approxi-mately 47 F to approximately 360 F between 4:00 p.m. January 25, and 4:30 a.m. January 27, 1972, and remained in the range of 34 - 36 F through January 30, 1972. The 6 T across the condenser was steady at 25 F until the power reduction that started at 10:42 p.m. January'27, 1972 (the five recirculation pump trip test).
Thereafter, ths & T decreased to fi10 F at 4:30 a.m. when the plant i was taken off line. During this period, three circulating pumps were pumping water through the condensers (total flow - 345,000 gpm).
i One dilution pump was in operation, except during this period from 10:00 p.m. January 25 to 12:01 a.m. January 27, 1972. One dilution pump moves approximately 250,000 gpm directly from the inlet canal to the outlet canal, bypassing the condenser.
Water from a creek named Oyster Creek enters the discharge canal j before the discharge canal leaves Jersey Central property. The - temperature of water leaving Jersey Central property is monitored by two thermocouples and recorded on a multipoint recorder.
Two additional thermocouples were installed but are inoperable. The recorder chart showed wide variations in temperature between the two points that are considered operable. This may be due to incomplete

Investigations . The - fish kill was investigated by the State of New Jersey and by .the Environmental Protection Agency (EPA). According to Mr. McCluskey, ' Mr. Paul Hamer, Marine Biologist from the Nacote Creek Fishery and , , Mr. Bruce Young, Conservation Officer from the Fish and Wildlife 5-Service, participated in the investigation for.the State.
Samples
- -
, , of dead fish were taken for laboratory analysis to determine the ! ' cause of the fish kill. Mr. Charles Amato told Mr. J. P. O'Reilly, , iDirector, Region I, that he would supply Region. I the results of '
this analysis. Jersey Central retained the services of a consulting a biologist to aid in this investigation of the problem. Mr. Ernest lKarvelis, Chief Biologist, represented the' EPA, , f i 6.
Publicity ' .The. fish kill story appeared as a front page article in the Asbury Park Sunday Press on January 30, 1972. Subsequently, at least.eight other newspapers carried a story or editorial on the subject. The . newspapers included: The Evening Times (Trenton, N. J.), Trentonian, i Trenton Times, Beach Haven Times, New York-Times, Morristown Daily Record, The Reporter (Toms River) and the Sunday Times Advertiser.

Description of Particular Event or Circumstance:
r.
Mr. McCluskey stated that a review and checkout of the ) , ! energency alarm procedures had been initiated. On January 22, , . 1972 at 1:15 pm the alarm, " Normal Emergency Power DC Interlock i Failure", was being tested. The test included transferring , l the electrical power from DC battery A to battery B (saing a " knife" switch). As a result of this transfer, the breakers for three recirculation ptanps and one feedwater pump, on .- the 4160 voit bus 1A, tripped. Mr. McCluskey indicated that: No abnormal flux or reactor water level were encountered.
