Dear Sirs:

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

Operating License No. DPR-73 Docket No. 50-320 Canister Handling and Preparation for Shipment Safety Evaluation Report, Revision 5 Attached for your review and approval is Revision 5 to the Safety Evaluation Report (SER) for Canister Handling and Preparation for Shipment (CHAPS). Only those SER pages which are affected by this change are attached. The proposed changes are described below:

o Section 2.3.1, " Verification of Canister Integrity," has been revised to delete an existing redundancy between the first and second paragraphs regarding canister dewatering and weighing. This revision, in part, deletes the minimum two (2) week holding time requirement for verification of canister integrity since it is not a valid criterion for determining canister integrity. Rather, this requirement was established to aid in verification of catalyst function using pressure indication (an alternate verification method) as described in Section 2.3.2. A minimum holding time of five (5) minutes, as specified in the second paragraph of Section 2.3.1, is sufficient to provide positive indication of loss of canister integrity.

Document Control Desk May 26, 1987 4410-87-L-0078 o Section 2.3.2, " Verification of Catalyst Function," has been revised to delete the estimated holding time for sampling canisters (i.e., 2 to 4 weeks) to detemine hydrogen and oxygen gas appearance rates following dewatering. The statement of estimated holding time is unnecessary and could lead to some confusion. The actual holding time, prior to gas sampling, is dependent on the schedular requirements for fuel shipping. The gas sampling results are used to determine an allowable storage time prior to canister shipment as further described in Section 2.3.2.

o Section 3.2 also has been revised to delete the 5% restriction on the number of canisters which can weigh up to 5% more than the prescribed limit of 2800 lbs. (i.e. 2940 lbs.). Based on discussions with EG&G, GPU Nuclear believes that the 5% restriction on the number of canisters which exceed 2800 lbs. is unnecessary provided that the 5%

excess weight restriction is absolute. GPU Nuclear will take every appropriate action to minimize the number of canisters which exceed 2800 lbs. in weight and will ensure that no canister weighing greater than 2940 lbs. is shipped.

GPU Nuclear requests that NRC review of proposed Revision 5 to the CHAPS SER be conducted concurrent with review of Revision 4 to the subject SER which was transmitted via GPU Nuclear letter 4410-87-L-0037 dated April 2, 1987.

Per the requirements of 10 CFR 170, an application fee of $150.00 is enclosed.
