4. Description of Error:

EOI 1003 Revision 2: Hosgri duct support qualifications for the TurbineBui ldin 4KV Switchgear Room HVAC Systems have not been located as ofOcto er 28, 1981 (Area A).

The PGKE duct support calculations dated prior to October 28, 1981 areincluded in the PGICE resolution package (Fray to Oenison - 6/15/82) P105-4-1003-008. These calculations are applicable to detail 5/440 and aretitled "Ventilation Duct Seismic Support 'Hosgri Evaluation'Auxiliar~Bui'Idio - Diablo Canyon

Revision 4 to this file was a Potential Error Report Class C. Based onthe 9/17/82 submittal of the DCP Phase I Final Report in which the OCP

has stated that the HVAC supports are being reanalyzed, the IOYP ProgramReview Committee on 9/29/82 decided to change this to an Error A or B.The IOVP also decided to combine File 1077 with this file.

5. Recoaeendation:

Error A or B,based on the ITP reanalysis effort stated in the OCP Phase IFinal Report (9/17/82 submittal). Because of ITP reanalysis the IQYPProgram Review comnittee changed to this from a Potential Error C

(Revision 4 of this file). The IDVP will also combine File 1077 on HVACsupports into this file.

Inappropriate application of computer code, CONTEt1PT, by NuclearServices Corporation (NSC) for calculation of environments outsidecontainment for equipment qualification in area GW results intoo low of an equilibrium temperature. SWEC's calculation usingcomputer code THREED results in a temperature of 313 F as comparedto NSC's temperature of 200 F .
