Subject:
Three Mile Island Nuclear Station, Unit 1 (TMI-1)
Operating License: DPR-50 Docket No.: 50-289 Request for Deletion of TMI-l Conditions of Operation 1(a) and 1(d)
Dear Sir:
The NRC authorized restart of TMI-l by letter, Denton to Hukill, dated October 2,1985, subject to certain conditions and requirements.
Because the TMI-2 cleanup has been completed and the plant is in a stable and safe, lona-term storage condition for Post-Defueling Monitored Sterage (PDMS), THI-1 Conditions of Operation 1(a) and 1(d) no longer have applicability and GPU Nuclear requests they be deleted.
Condition 1(a) reads:
i (a)
During any Unit 2 fuel movements in the fuel handling building, GPU Nuclear Corporation shall suspend work in the Unit I area of that building, unless GPU Nuclear Corporation has submitted to the NRC for its review specific written procedures for the planned gja movements of Unit 2 fuel and an evaluation of the potential impacts of those fuel movements on personnel working in the Unit 1 area of ig the building and the NRC has agreed that the potential impacts of wreE the planned Unit 2 fuel movements on personnel working in the Unit i@g$'
I area of the building do not require that work in the Unit I area of the building be suspended.
LBP-82-27, 15 NRC 747, 755 (1982) eJ og Permanent relief is requested from Condition of Operation 1(a) because the j
gg TMI-2 Unit has been defueled and the fuel has been shipped offsite. No o5 movement of the residual TMI-2 fuel is planned during the remaining term of M
the TMI-l operating life. The TMI-2 Fuel Pool has been covered by an O
environmental barrier which prevents the migration of any residual loose gno radioactive contamination from the TMI-2 Fuel Pool.
Therefore there is no potential for any impact on TMI-l personnel from TMI-2 fuel mc.vements in the Fuel Handling Building.
GPU Nuclear Corporation is a subsidiary of General F#he Utilities Corporation I d9 07001G

Cobition1(d) reads.
Isolation of liquid transfer line interconnections between Units 1 and 2 I
shall be maintained. LBP-81-59, 14 NRC at 1432-33; LBP-82-27, 15 NRC 747.
Permanent relief is requested from this condition of operation so that liquid i
transfer between Unit I and Unit 2 may be utilized to f.cilitate treatment of radioactive waste.
Condition 1(d) was instituted to ensure that the decontamination and/or restoration operations at TMI-2 would not affect safe operations at TMI-1. At the time the condition was imposed, the TMI-2 cleanup involved the processing of millions of gallons of highly contaminated water which required special and unique water processing systems and controls.
t The TMI-2 cleanup has been completed. The TMI-2 plant has been placed in a safe and stable, long-term storage condition. There are no large scale decontamination and/or restoration activities planned or ongoing which will i
generate significant volumes of water to be processed. The processing of 2.3 i
million gallons of highly contaminated water generated by the TMI-2 accident j
has been completed and the water has been disposed by evaporation. No accident generated water remains at TMI-2.
Planning is underway to interconnect the TMI-1 and TMI-2 liquid radwaste treatment systems to enable the transfer of liquid waste via common waste processing lines so that liquids from either Unit can be processed as needed i
by either TMI-1 or TMI-2 water processing systems. The treatment of liquid waste from Unit 2 by Unit I will not affect safe operation of Unit 1.
Further, maintaining a capability to process Unit 1 liquids at Unit 2 enhances safe operation of TMI-1.
In addition, relief from Condition 1(d) will permit the processing of the relatively small amount of contaminated liquid expected to accumulate at TMI-2 during PDMS by either TMI-1 or TMI-2 liquid processing i
systems.
The maximum projected volume of THI-2 liquid that could require processing during PDMS is 5000 gallons per year; slightly more than 1% of the projected volume of TMI-1 liquid that will require processing.
The TMI-2 water is expected to be generated by building in-leakage during PDMS and will contain low concentrations of radioactive materials.
Conditions 1(a) and 1(d) are two of the remaining TMI-1 Conditions of Operation imposed at the time of Restart.
The conditions of Operation are not part of the TMI-1 License or Technical Specifications.
GPU Nuclear views the TMI-1 Conditions of Operation as conditions imposed by NRC Order and is requesting relief by letter.
