- 1) Letter from L. L. Kintner (NRC) to W. T. Cottle (GGNS),
" Grand Gulf Nuclear Station, Unit 1 (Grand Gulf) - Final Analysis Required'by 10CFR50.44", MAEC-90/0193, dated August-10, 1990
- 2) Letter from Ashok C. Thadani (NRC) to J. R. Langley (HCOG), " Acceptance for Referencing of Licensing Topical Report Titled, ' Generic ' Hydrogen Control Information for BF'.-6 Mark III Containments' ", HGN-112-NP, dated August 6, 1990 GNRO-91/00036 Gentlemen:
Grand Gulf Nuclear Station-(GGNS) was requested by Reference 1 to submit the Hydrogen Control Final Analysis by March 1, 1991. GGNS is unable to
-respond by the currently scheduled date because resolution of generic hydrogen control issues between the Hydrogen Control Owners' Group (HCOG) and the Nuclear Regulatory Commission (NRC) is pending. The outcome of these generic _ issues currently under discussion will af fect the content of the GGNS Hydrogen Control Final Analysis.
Therefore, by way of this letter, GGNS is notifying the NRC that the originally scheduled submittal date of March 1,1991 for the GGNS Hydrogen Control Final Analysis will not be met.
This original date was based on receiving a SER with no remaining open issues. As previously noted and discussed below, HCOG considered the generic SER to have several items that required additional clarification and thus HCOG was unable to meet-its originally scheduled submittal date. As a result, it is GGNS' intent to now submit its Hydrogen Control Final Analysis within six months af ter submittal of the HCOG t.ccepted Topical Report.
