Thren Mile Island Nuclear Station, Unit 2 (TMI-2)

Operating License No. DPR-73 Docket No. 50-320 Technical Specification Change Request (TSCR) No. 56 - Revised The Licensee requests that the attached changed page (i.e., Page 3.9-3) replace the corresponding page of the TMI-2 Technical Specifications.

Description of Change This proposal deletes the current prohibition on disposal of Accident Generated Water, as imposed by Technical Specifications 1.17, 3.9.13, and 3/4.9.13. However, this proposal retains the requirement for prior NRC approval of procedures associated with the disposal of Accident Generated Water.

Reason for Change GPU Nuclear letter 4410-86-L-Oll4 dated July 31, 1986, " Disposal of Processed Water," requested NRC approval for disposal of the TMI-2 Accident Generated Water by evaporation. This submittal also evaluated the need for a revision to the TMI-2 Technical Specifications and concluded that it was not required.

However, based on Section 2.3.5 of the Draf t Supplement 2 to the Programmatic Environmental Impact Statement - Three Mile Island, Unit 2 (PEIS), GPU Nuclear understands that the NRC will require the TMI-2 License to be amended prior to disposal of this water.

Safety Evaluation Justifying Change Technical Specification 3.9.13, " Accident Generated Water," prohibits the discharge of Accident Generated Water, as defined in Technical Specification 1.17, until approval has been obtained from the NRC. Additionally, Technical Specification 3.9.13 requires that Accident Generated Water be discharged in accordance with procedures approved by the NRC pursuant to Specification 6.8.2. The basis for this requirement is provided in Technical Specification Basis 3/4.9.13, " Accident Generated Water," which states:

"These specifications are provided to ensure compliance with the Commission's Statement of May 25, 1979, and the Commission's Statement of Policy and Notice of Intent to Prepare a Programmatic Envirorgnental Impact Statenent of November 21, 1979, which prohibit these actions pending evaluation of the environmental impacts of such actions. The PEIS issued in March, 1981, deferred a decision on the ultimate disposal of processed water. Further Commission action is necessary prior to release of ACCIDENT GENERATED WATER.

However, the Commission has recognized that there may be emergency situations, not at this time foreseen, which could require rapid action.

In these situations, the Commission has indicated its intention to consult with the Council on Environmental Quality to the extent practicable."

As stated above, the primary basis for requiring NRC approval prior to discharge of Accident Generated Water is to ensure compliance with the Programmatic Environmental Impact Statement (PEIS). On July 31, 1986, CPU

( .

Nuclcar 13ttsr 4410-86-L-0114, FDisposal of Proc:ssed Watsr," provided technical and environmental justification in support of a request for NRC approval to dispose of Accident Generated Water. This submittal has been supplemented by GPU Nuclear letter 4410-86-L-0178 dated October 21, 1986, which responded to NRC comments on this subject and GPU Nuclear letters 4410-87-L-0018 dated February 3,1987, and 4410-87-L-0023 dated February 18, 1987, which provided additional information on the radiochemistry of the processed water.

GPU Nuclear holds that the information contained in the above submittals clearly demonstrates that the disposal of the Accident Generated Water, as proposed, can be performed safely and provide adequate justification to revise Technical Specification 3.9.13 to delete the prohibition on discharge of the water. The effluent releases from the proposed disposal of Accident Generated Water will be maintained within the limits imposed by TMI-2 Appendix B Technical Specification 2.1.2, " Gaseous Effluents."

Significant Hazards Consideration 10 CFR Paragraph 50.92 provides the criteria which the Commission uses to evaluate a No Significant Hazards consideration. 10 CFR 50.92 states that an amendment to a facility license involves No Significant Hazards if operation of the facility in accordance with the proposed amendment would not:

1. Involve a significant increase in the probability or consequences of an accident previously evaluated; or

2. Create the possibility of a new or different kind of accident from any accident previously evaluated; or

3. Involve a significant reduction in a margin of safety.

Although the disposal options for the TMI-2 Accident Generated Water differ from the disposal options for liquid wastes outlined in previous evaluations (e.g., THI-2 FSAR), the consequences of these activities are bounded by existing analyses as discussed in Section 7.1 of GPU Nuclear letter 4410-86-L-Oll4.

GPU Nuclear letter 4410-86-L-Oll4 also concluded that the disposal options considered would not increase the probability of an accident previously evaluated nor would it create the possibility of a new or different kind of accident. Further, it concluded that the disposal of the Accident Generated Water does not involve a significant reduction in a margin of safety. The analyses presented in GPU Nuclear letter 4410-86-L-Oll4 demonstrated that the off-site exposures from the disposal of the Accident Generated Water were well within the regulatory limits of 10 CFR 50, Appendix I and the limits imposed by Appendix B to the TMI-2 Technical Specifications.

Thus, based on the evaluation provided in CPU Nuclear letter 4410-86-L-Oll4, it is concluded that the changes proposed in this Technical Specification Change Request involve No Significant Hazards as defined by 10 CFR 50.92.

Amendment Class Pursuant to the requirements of 10 CFR 170, Licensing Fees, an application fee of $150.00 is enclosed.
