Dear Sirs:

Three Mile Island Nuclear St etton, Unit 2 (TMI-2)

Operating License No. DPR-73 Docket No. 50-320 Safety Evaluation Report for Completion of Lower Core Support Assembly and Lower Pead Defueling - Revision 1 GPU Nuclear letter 4410-08-L-0006 dated June 6,1988, submitted the Safety Evaluation Report for Completion of Lower Core Support Assembly and Lower Head Defueling for NRC review and approval. Section 5.0, "Radiological Conditions" of that submittal comitted to provide an update of the expected occupational exposure to complete Reactor Vessel (RV) defueling and the jobhours and person-rem expended to date for defueling activities. Attached, as Revision 1 to the subject document, is that information. Only the affected pages of the original document are provided (i.e., pages 3, 18 - 27).

GPU Nuclear currently estimates that approximately 1580 person-rem (i.e., an increase of 180 person-rem) will be required for completion of RV defueling.

This increase is primarily due to an increase in defueling support activities such as operation and maintenance of the Automated Cutting Equipment System.

! A revised Table 5-1, updated to May 31, 1988, indicates that 1028 person-rem l

have been expended for RV defueling activities. A separate activity, entitled l

"Defueling Support," has been added to this table to more precisely reflect the activities associated with RV defueling.

Sincerely, 1
