C. 20555 Shoreham Decommissioning Project Termination Survey Plan - Revision 3 Shoreham Nuclear Power Station - Unit 1 Docket No. 50-3AR Ref: (1) Long Island Power Authority letter LSNRC-2133 dated January 1,1994; subject: Termination Survey Plan - Revision 2 (2) Nuclear Regulatory Commission letter dated June 7,1994; subject:

Approval of a Modification of Facility Release Criteria for Tritium and iron-55 Surface Contamination at Shoreham Nuclear Station, Unit 1 (3) Long Island Power Authority letter LSNRC-2144 dated February 4,1994; subject: Termination Survey Final Report Phase 2 and Application for Withholding Per 10 CFR 2.790 Ladies and Gentlemen:

1 Enclosed is the latest revision of the Shoreham Decommissioning Project Termination l Survey Plan which supersedes the version previously transmitted in Reference 1. This i Revision 3, forwarded as Enclosure 1, incorporates information on an additional pipe crawler utilized for the survey of 2 inch diameter piping. The revision also identifies certain survey units (areas of the facility) which are impacted by "hard-to-measure" isotopes, provides the ratios of these isotopes to more commonly detected nuclides, and states the resultant gross activity guidelines (GAG) to be applied to the survey units. These GAG values have been determined following the methodology of Appendix A of NUREG/CR-5849. A detailed discussion of the activation calculations and sample analysis performed to establish the isotopic ratios as well as the calculations for determination of GAG values for each specific survey unit is included as Enclosure 2 to this letter. Finally this revision updates the stated facility release criteria, accounting for modifications provided in Reference 2.
