Dear Mr. O'Reilly:
Operating License EPR-50 Docket No. 50-289 In accordance with the Enviren= ental Technical Specifications for cur Three Mile Island Nuclear Station, Unit 1, we are reporting the following Enviren= ental Incident: ,77i; h '

(h) Identificaticn of Incident:
Failure to monitor the release of icdine frcm the Auxiliary and Fuel Handling Building due to the removal frc= service of the icdine channel of Radiaticn Mcnitor A-8, which is a violation of the monitoring requirenents of the Enviren= ental Technical Specificaticns, paragraph 2.3.2.A.2.
(5) Conditiens Prior to Cecurrence:
The reacter was at steady state pcuer with major plant parameters as follevs:
Power: Co~ - ' OC",
Elec.: 855 lG (Gross) }khk 1082:
6 RC Flow: 139 x 10 lb/hr RC Pressure: 2163 psig RC Temp.: 579cy PRZE level: 2h3 in PEZ3 Temp.: 6L7 F (6) Description of Incident:
At 2130 hcurs on Septe=ber 28, 197k, the iodine channel cf Radiatica Monitor A8 was re=oved frc= service fer calibration while a release was being =ade frc= a vaste gas tank. The release was ccepleted before the channel was returned to service.
(7) Designation of Apparent Cause of Incident:
It is believed that the incident in question was caused primarily by the fallare cf Plant Maintenance eersennel to follow approved procedures, in that they re=oved a radiation monitor channel frc=
service withcut first infor=ing the Shift Superviscr.
(8) Analysis of Incident:
It is believed that the failure to =cnitor the iodine release rate did not cause any environ = ental damage and did not represent a threat to either the health or safety of the public, in that the contents of the vaste gas tank were analy.:ed prior to their release, no iodine activity was detected, and the release rate did not exceed the Technical Specification limits.
(9) Corrective Action:
The folleving short-ter: corrective acticns were taken:
- a. The importance cf following all applicable precedures was impressed upon the Instrument Fore =an and instrument technicians.
- b. A Superintendent's Operating Memn Las sent to all apprcpriate plant perscnnel directing thea to infor= the appropriate foreman of any propcsed action on a safety related syste= requested by a vendor representative and to inform the Shift Supervisor of any preposed work to be done on a safety related system.
At a meeting held t=nediately after the incident was repcrted, the Plant Operations Eeview Cc==ittee (PCEC) reviewed and gave its approval of these acticns. In addition, they recc== ended to the Station Superintendent that the folleving 1cne-ter= ccrrective actions be taken:
- a. Review the procedure which controls the removal of radiation
=cnitors frc= service and add any furthe. cautions which =ay be required.
\h0\
, ~
- b. Investigate the feasibility of adding key-lcek switches to the defeat circuit for the radiation scnitor interlocks.
The Station Superintendent concurred with these recc= endations and has taken the necessary steps to incure their implementation.
(10) Failure Data:
Not applicable.
Sincerely, I-l
