SUBJECT:

Grand Gulf Nuclear Station Units I and 2 Docket Nos. 50-416 & 50-417 License No. NPF-13 File: 0260/L-860.0 Additional Informaton - TDI Diesel Generators AECM-84/0392 Various commitments related to the TDI diesel generators were made in the Mississippi Power & Light Company (MP&L) letters dated July 20,1984 and July 26, 1984. This letter provides confirmation of the completion of these commitments,

l. Addition of precautionary statement in the " loss of offsite power" procedure - A statement has been added to the subject Off-Normal Event Procedure by change notice dated July 20, 1984. This note specifies the 5740 kw (equivalent to 185 psig BMEP) limit on diesel generator loading during this off-normal event. The statement advises the operator that the Division I and Division 11 diesel generator may, if necessary, be used to carry additional plant loads.

This precautionary statement in conjunction with the proposed technical specification to limit the loads during testing, responds to the NRC request to prevent unnecessary loading of the engines above 185 psig BMEP. The proposed technical specifications were transmitted as PCOL-84/17 (MPAL letter, dated July 20,1984).

2. Training on the above precautionary statement - Training on the procedure change will be included in the training package for Amendment 13 to the Facility Opercting License. This amendment is expected to include related technical specification revisions. The training package will be initiated following receipt of the amendment.

3. Confirmatory walkdown of the engine fuel oil lines - As noted in the letter dated July 26, 1984, a confirmatory walkdown has been completed. Several areas of concern were noted on the Division 11 engine fuel lines. Corrections of these conditions have been completed. The corrections were performed by replacing or rerouting the affected lines.
