SUBJECT:

GENERAL ELECTRIC REPORT, "EVALUATION OF EFFECTS OF POOL SWELL IN THE MARK-I AND MARK-II CONTAINMENTS,"

NEDM 20725-01, DATED NOVEMBER, 1974

Reference:

Letter, "Mark II Containment," to R. F. Boyd (NRC) from I. F. Stuart (GE), dated January 15, 1976, GE-MFN 008-76 The subject report was submitted to the NRC in January 1976. Although never intended for distribution outside General Electric, ten (10) copies were provided to the Staff as requested, because NEDM 20725-01 had been referenced in the Mark II DFFR, NEDO 21061, [Revision 0],

dated September '1975.

As stated in the referenced letter, inclusion of NEDM 20725-01 as a DFFR reference was unnecessary because the analytical model contained in the report had been provided in DFFR, Revision 0. The subsequent DFFR Revisions 1 and 2, which entirely superseded the respective previous revisions, therefore did not include reference to NEDM 20725-01.

Because the report NEDM 20725-01 is not referenced in the presently applicable DFFR (Revision 2) and the pool swell.. model has been described in the Pool Swell Model Repor t, NEDO/NEDE 21544P, submitted as part of the Mar k II Supporting Program in February, 1977, the unpublished NEDM 20725-01 has no application in the Mark II Program.

GENERAL ',i ELECTHIC Mr. John F. Stolz Page 2 February 21, 1978 Please withdraw report NEDM 20725-01 from consideration as part of the Mark II Program; destroy or return those copies in your possession.

Any questions regarding this matter should be directed to L. H. Frauenholz, the Mk II Containment Licensing Engineer, (408) 925-2623.

Sincerely,
