1. Liquid Effluent Concentration 1
a. Waste Monitor Tank #2 has the following radionuclide concentrations:

1.0E - 03 p c 1.0E - 05 p c"/mL Soluble

/mL Soluble Fr 59 Cr 51 2.0E - 05pc,/a4 Soluble C 60

~

1) Can the contents of this tank be released per T.S. 3.11.1.1. -
b. Although each concentration is below MFC, REF: 10CFR20 collectively using the formula Ca/MFC at AFF B. Table II, j Cb/MFC + Cc/MFCc + ... + C,/MFC, 1 1.0E - 03/2.0E - 03 (MFC for CR51) +

1.0E - 05/6.0E - 05 (MFC for ca 59) +

2.0E - 05/5.0E - 05 (MFC for Co 60) = 1.066 1.066 1.0 therefore the tank must be diluted before releasing or reprocessed.

2. Gas Decay Tanks (GDT)
a. The shif t chemist reports that the noble gas radiommelide concentration of the on-service Gas Decay Tank is 2.2 E05 curies. W at actions are required by Tech Spect (limit 2.0 E05 cu)
1) Insure that all additions to the on-service Gas Decay Tank are secured or remove that tank from service per 13201-1 " GASEOUS WASTE PROCESSING SYSTEM".

LO-LP-39215-00 3.11.1.1 Liquid Effluent - Concentration (295] SUMMER 1 DOCKET 50-395 LER 84-048 UNMONITORD LIQUID RELEASE.

EVENT DATE DATE: 121784 REPORT DATE: 011485 NSSS: WE TYPE: PWR (NSIC 193508) ON 12-17-84, WITH TH PLANT IN MODE 3. THE LICENSEE MADE AN UNMONITORED LIQUID RELEASE. THE CAUSE OF THIS EVENT WAS DUE TO AN IMPROPER VALVE LINE-UP. THERE I WERE NO ADVERSE CONSEQUNCES DUE TO THIS EVENT. ACTIVITY THAT WAS INDICATED ON THE LIQUID RADWASTE EFFLUENT LINE MONITOR WAS DUE TO ENTRAPPED FLUID FROM A PREVIOUS RELEASE WHICH HAS BEEN MONITORED. THE OPERATIONS PROC EURE FOR LIQUID RADWASTE DISCHARGE IS BEING REVISE TO CLARIFY VALVE AND SWITCH ALIGNMENT. A COPY OF THIS REPORT WILL BE PLACED IN THE OPERATION'S REQUIRED READING BOOK AND SHIFT SUPERVISORS WILL REVIEW THIS EVMT WITH ALL SHIFT PERSONNEL. THIS ACTION WILL BE COMPLET E BY 3-1-85.

THE EVENT WAS CAUSED BY SEAT LIAEACE TEROUGE IWG41 (CAS DECAY TANK VWT C0HROL VALVE), WEICE WAS BEING UTILIZED AS AN ISOLATION VALVE FOR TH LEAK CEECK. TER PLANT VENT MONITORS WERE OPERATIONAL, AND TEE INADVERTENT RELEASE WAS MONITORED AND RECORD E. EVALUATION OF i THE STRIP CHART RECORDERS REVIALE TEAT TEI ACTIVITY RELEAS E WAS WELL WITHIN I PRESCRIB E LIMITS. BECAUSE A PRE-LEASE SAMPLE WAS NOT OBTAINED AND ANALYZE AS REQUIRED BY TH INV TECH SPECS, THE EVENT IS REPORTABLE IN ACCORDANCE WITE 10 CFR 50.73 (A) (2) (I) (B). TEERE ARE PRESENTLY NO REQUIREMENTS TO PERIODICALLY LEAK TEST 1WG413 HOWEVER INGINEERING IS PRESWTLY INVESTIGATING TEE WASTE GAS ANALYZER SYSTEM DESIGN CRITERIA, #3D DETERMINING TEE NEED FOR PERIODIC TESTING.

EVENT DATE: 092484 REPORT DATE: 102484 NSSS: CE TYPE: PWR OTHER UNITS INVOLVED: SAN ONOFRE 3 (PWR)

VENDOR: GRINNELL CORP.

(NSIC 192434) ON 9-24-84 AT 1610. WITH UNITS 2 AND 3 IN MODE 1 AT 100% POWER, THE LOW LEVEL ALARMS WERE RECEIVED ON PLANT VENTILATION STACK MONITORS 2RE-7865 AND 3RE-7865. THE MONITORS LEVELS INCREASED TO A PEAK OF 9.5E-4 UCI/CC ON WAS TERMINATED AT 1632 WHEN THE GASEOUS RADWASTE PROCESSING GAS STRIPPERS WERE BYPASSED.

THE SOURCE OF THE RELEASE WAS LATER TRACED TO THE SOUTH GAS STRIPPER. THE CAUSE OF THE RELEASE WAS DETERMINED TO BE THE FAILURE OF SOUTH GAS STRIPPER PREHEATER DRAIN VALVE SA1901MU702 WHICH ALLOWED A MIXTURE OF UNIT 3 PRESSURIZER DEGAS EFFLUENT AND T067 and T068 RECIRC TO ESCAPE VIA THE FLOOR DRAINS INTO THE RADWASTE BLDG VENTILATION SYSTEM WHICH EIHAUSTS TO THE PLANT VENT STACK. THE RELEASE WAS APPROX 117.5 CURIES OF IE-133. THE CONCENTRATION IN UNRESTRICTED AREAS, WHEN AVERAGED OVER 1 HR, WAS 7.8E-7 UCI/CC (2.6 TIMES THE APPLICABLE CONCENTRATION IN APPENDIX B, TABLE II 0F 10 CFR 20). THE RELEASE WAS WIIRIN TECH SPEC LIMITS. GAS STRIPPER PREHEATER DRAIN VALVE SA1901MU702 WAS REPAIRED, SUCCESSFULLY TESTED, AND RETURNED TO SERVICE.

(NSIC 193424) ON 1-17-85 AT 0503, WITH UNIT 2 DEFUELED AND UNIT 3 IN MODE 1 AT 100% POWER WHILE PLACING THE NORTH GAS STRIPPER IN SERVICE, A HIGH RADIATION ALAIM WAS RECEIVED ON PLANT VENT STACK MONITOR 2/3-7808C. IN ACCORDANCE WITH TECH SPEC 3.11.2.1, STEPS WERE TAKEN TO TERMINATE THE RELEASE AND THE RELEASE WAS SECURED AT APPROX 0700. OUR EVALUATION OF THE SITE BOUNDARY CONCENTRATIONS. INDICATES A MAX CONCENTRATION, WHEN AVERAGED OVER 1 HR, OF 4.42 MFC. THIS RELEASE WOULD RESULT' IN A DOSE TO A PERSON, AT THE SITE BOUNDARY, OF 0.07 MREN. A TOTAL OF APPRDI 306 CI (NOBLE GAS) WAS RELEASED. THE CAUSE OF THE RELEASE WAS LEAKING DRAIN VALVES ON THE NORTH GAS STRIPPER PEEEEATER AND REGENERATIVE HEAT EXCHANGER MANIPOLD.

MAINTENANCE ORDERS HAVE BRIN 155UED TO REPAIR THESE VALVES. THE VALVES iiILL BE l REPAIRED AND TESTED PRIOR TO RETURNING TEE NORTH GAS STRIPPER TO SERVICE. SIMILAR EVENTS REPORTED IN LER 361/84-054.
