Dear Mr. Tucker:
SUBJECT:
HYDROGEN RECOMBINER SYSTEM-REQUEST FOR ADDITIONAL INFORMATION REGARDING:
Oconee Nuclear Station, Units 1, 2 and 3 By letter dated February 12, 1986, you proposed an amendment to the Technical Specifications on the operation and maintenance of the containment hydrogen recombiner system. This system will be used as the primary method to maintain the post-accident containment atmosphere hydrogen concentration below the control limit.
To complete our review, we need the additional information identified in the enclosure. We request that you respond to this request for additional information within thirty days of receipt of this letter. The reporting and/or recordkeeping requirements contained in this letter affect fewer than ten respondents; therefore, OMB clearance is not required under P.L.96-511.

ENCLOSURE REQUEST FOR ADDITIONAL INFORMATION OCONEE NUCLEAR STATION UNITS 1, 2 AND 3 HYDROGEN CONTROL SYSTEM
- 1. Provide the following information on the external hydrogen recombiner used at the Oconee plant:
- a. Identify the type of recombiner. Reference to the manufacturer's literature could be made if the recombiner is of a standard design.
If, however, it is a custom made unit, detailed design information, including design drawings, should be provided.
- b. Describe the installation of the recombiner in the Oconee plant.
The description given in the Final Safety Analysis Report (FSAR) does not give sufficient information to enable us to review the operation of the system. Provide a detailed installation drawing which clearly shows how the recombiner interfaces with existing plant systems.
- 2. Identify the alternate power sources to be used for operating the recombiner system during a loss of offsite power.
