SUBJECT:

Grand Gulf Nuclear Station Unit 1 Docket No. 50-416 License No. NPF-29 Response to NRC Comments on Process Control Program, Revision 1 AECM-86/0337 By letter dated August 31, 1984 (AECM-84/0438), Mississipoi Power & Light Company (MP&L) submitted for NRC review the Grand Gulf Nuclear Station (GGNS) Process Control Program (PCP), Revision 1, as Attachment II to the GGNS Semiannual Radioactive Effluent Release Report. Review of the PCP, Revision 1, by the NRC generated a request for additional information which was provided to MP&L by NRCletter(MAEC-86/0101) dated April 8, 1986.

Attachment I provides MP&L's responses to the concerns noted by the NRC.

The appropriate responses have been incorporated into the PCP, Revision 2, which is included as Attachment II to this letter. Attachment III is a detailed explanation of the changes incorporated in this revision of the PCP.

If you require additional infornation, please advise.

ATTACHMENT I This attachment provides the additional information requested in your letter of April 8, 1986 regarding the Grand Gulf Unit 1, Process Control Program, Revision 1. MP&L has revised the PCP as appropriate and considers that no further revision is necessary at this time. The revised PCP is provided as Attachment II to this letter.

1. Question

" State if the permanent solid radwaste system, as installed at Grand Gulf Nuclear Station, Unit No.1, and as described in the Grand Gulf FSAR Section 11.4, has been utilized for solidification of wet waste."

Response

The permanent solid radwaste system, as installed at Grand Gulf Nuclear Station, Unit No.1, and as described in the Grand Gulf FSAR Section 11.4, has not been utilized for solidification of wet waste. Vendor services are currently employed for the processing of wet wastes.

2. Question

" State if Grand Gulf has utilized a contractor to process wet waste.

If so, provide the following information:

i o Name of contractor; o Type of system (mobile, dewatered, etc.);

o Reagent used; o Contractor's Process Control Program; o Type of waste container used."

Response

o Dewatering of resins is currently performed on-site by Chem-Nuclear Systems, Inc. (CNSI) using a mobile dewatering system.

o The CNSI mobile dewatering skid includes the following equipment: air driven dewatering / transfer pump with manual isolation valves; level indicator; and necessary hoses, o No reagents are used during the process.

o Chem-Nuclear's Topical Report, CNSI-DW-11118-01, has been approved by the USNRC. Dewatering is performed according to Chem-Nuclear's procedures which have also been reviewed and approved by the GGNS Plant Safety Review Committee. (CNSI Document Numbers: F0-0P-022 "Ecodex Precoat/Powdex/Solka-floc / Diatomaceous Earth Dewatering Procedure for CNSI 14-195 or Smaller Liners" and F0-0P-023 " Bead Dewatering Procedure for CNSI 14-195 or Smaller Liners".)

o Resins are,dewatered in steel liners or polyethylene High Integrity Containers as is necessary. (Currently using CNSI Stock Numbers: L14-195BTCR, L14-195BTFEX, and PL14-195FEX).

3. Question

" Describe the waste classification program for meeting the requirements specified in Section 61.55 of 10 CFR 61."

Response

WASTETRAK, a computerized waste classification program, complies with 10CFR61.55 and is currently the primary method of calculating activities and classifying waste. As a backup method to the computer program, Grand Gulf Nuclear Station Plant Operations Manual, Radwaste Instruction #08-S-06-11 " Classification of Radwaste" provides a means for classifying radwaste in accordance with 10CFR61. This procedure includes instructions regarding sampling and analysis of gamma emitting nuclides; scaling tritium, alpha- and soft beta-emitting.nuclides; evaluating waste characteristics; and determining the presence of chelating agents.

methods to be used to obtain samples of low-level radioactive waste streams for determining isotope concentrations in the waste and to ensure that shipments of radioactive waste are properly classified as to their radionuclide composition and activity levels in compliance l

with 10CFR61.

4. Question

" Describe the compliance program for meeting the waste stability requirements set forth in Section 61.56 of 10 CFR 61."

Response

To date, all radwaste generated at GGNS has been Class A. Grand Gulf Nuclear Station Plant Operations Manual, Radwaste Instruction

1. 08-S-06-11 " Classification of Radwaste" provides administrative requirements for ensuring the compliance with braste stability requirements for Class B and C waste in accordance with 10CFR61.56. Due to limited crane capacity in the radwaste processing area, GGNS intends to dewater resin and filter aid media in High Integrity Containers when necessary, in lieu of solidification, to meet stability requirements.

5. Question

" State if Grand Gulf is planning or considering to increase the waste storage capacity beyond that described in the Grand Gulf FSAR."

Response

Grand Gulf is not planning to increase the waste storage capacity beyond that described in the FSAR.
