Dear Dr. Snyder:
Three Mile Island Nuclear Station, Unit 2 (TMI-2)
Operating License No. OPR-73 Docket No. 50-320 Auxiliary and Fuel Handling Building Decontamination Schedule In accordance with your letter dated March 7, 1984, the following is the status of the Auxiliary and Fuel Handling Building Decontamination Scnedule for the third quarter of 1985. This update lists only those l
areas where Technical Specification Surveillances are not being performed l
due to ALARA considerations.
The emphasis of recent decontamination has been directed to support activities related to the def ueling effort. Decontamination efforts in the areas listed below have been held to a minimum as previously discussed with members of your staff.
Make-up Filter Cubicle ALARA exemption is being taken for Technical Specification Surveillance 4210-SUR-3775.02 (4331-R3), " Fire Barrier Penetration Fire Seal Inspection".
During this past quarter, this cubicle remained inaccessiole due to the housed portions of the Make-up and Purification Cesium Elution Process.
The radiation dose rate for the general area is 800 mr/hr with hot spots up to 1.25 R/hr.
Removal of the elution equipment has been approved, but is currently on g
- ()b0 hold pending an Radiological Engineering review.

Dr. 6. J. Snyder October 15, 1983 4410-85-L-0204 Seal Injection Cuoicle ALARA exemption is currently being taken for Tecnnical Specification Surveillance 4210-SUR-3244.01 (4301-M8), " Containment Integrity Verification".
During the past quarter, no additional decontaminat.fon activities were performed in tnis cubicle due to the high radiation levels. The gamma radiation dose rate for the general area is 25 R/hr with hot spots up to 110 R/hr.
Decontamination efforts are still in the planning stage. GPU Nuclear is 7
continuing to develop remote techniques for decontaminating this cubicle.
r Additionally, a cubicle ventilation system nas been designed to ennance the accessibility of tnis cubicle.
Make-up Pump Suction and Discharge Valve Alley ALARA exemption is being taken for Technical Specification Surveillance 4210-SUR-3775.02 (4331-R3) and 4210-SUR-3775.01 (4331-A1), " Fire Barrier Penetration Fire Seal Inspections".
General area radiation dose rates for this cubicle range from 100 mR/hr in the suction alley to 1.5 - 5 R/hr in the disenarge alley.
No decontamination activities where performed in this cuoicle during the past quarter. As a prerequisite to eventual pipe flushing, a fuel characterization will be performed in this cubicle during this coming quarter.
305' Elevation Make-up Valve Alley O
ALARA exemption is being taken for Technical Specification Surveillance 4210-SUR-3775.02 (4331-R3), " Fire Barrier Penetration Fire Seal Inspection."
The general area radiological dose rate is approximately 400 mR/hr. A few hot spots, which average 2-3 R/hr remain in the piping and related components along with a hot spot of 20 R/hr 'at the floor drain.
An engineering evaluation for internally flushing the piping is being performed. This flushing is planned to be performed once the Make-up Filter Cuoicle is accessible.
