DOCTI NO. 50-146 4 LICENSE NO. DPRk lb q omsgce P Proposed Revision of Supplement No.1 to the V Saxton Technical Specifications It is proposed that Supplement No.1 to the Technical SIecifications incorporating changes applicable to conduct of Phase 1 of the Saxton five-year resenreh and develoinent program be revised as follows in order to provide for changes and additions to the phase 1 experimental program as described in Supple-ment No.1 to the safeguards Report for the Phase 1 experimental program.
