STN 50-498, STN 50-499 Response to NRC Question 331.8 of the FSAR Attached for your information and use is a proposed change to the subject response as given on page Q&R 12.3-3 of the South Texas Project Electric Generating Station (STPEGS) FSAR. The proposed change does not affect the Safety Evaluation Report for STPEGS Units 1 and 2, NUREG-0781.

This proposed change updates the response to reflect the current design of the STPEGS Fuel Handling Building and resolves comments made by USNRC Region IV Inspector H.D. Chaney. The proposed changes indicated will be submitted in a future FSAR Amendment. These changes are necessary to prevent personnel access to high radiation areas during transfer of spent fuel and will be implemented prior to movement of spent fuel through the transfer tube.

Attachment ST-HL-AE-2039 File No.: G9.01 Page 2 of 2 INSERT 1

Response

There are two access paths to the unshielded area adjacent to the fuel transfer tube in the Fuel Handling Building:

1. Via a ladder up from Room FHB-011 at elevation (-) 13'0" to Room FHB-112 at elevation 21' 2 1/2" (as shown in Figures 1.2-39 and 1.2-40);

2. Via a ladder down from Room FHB-304 at elevation 68'0" to Room FHB-112 at elevation 21' 2 1/2" (as shown in Figures 1.2-40, 1,2-41, and 1.2-42).

To restrict access to the area adjacent to the fuel transfer tube, STP will:

1. Provide lockable, grating type, barriers at the points of access to the ladders in Rooms FHB-011 and FHB-304;

2. Insure, through procedural requirements, that the appropriate barriers and doors to Room FHB-112 are locked closed prior to and during the transfer of irradiated fuel through the fuel transfer tube;

3. Conspicuously post these barriers in accordance with 10CFR20.203(c) and other applicable project requirements.

The keys to these barriers and doors are under the administrative control of the Security Force Coordinator.
