SEP 5 1980 Request for Additional Information Structural Engineering Branch Washington State University Research Plant Docket No. 50-27 1.

Provide sufficient details (discussion and sketches) of the reactor pool structure and interior.

2.

Provide a description of all objects which may be moved over the pool. State which of these objects is the critical one and also state whether a postulated accident with this -object has been considered in the design of the pool and the interior.

3.

Indicate whether any fuel racks are in the pool and, if so, to what extent the pool and the racks conform with the NRC position on fuel pools entitled "0T Position for Review and Acceptance of Spent Fuel Storage and Handling Applications", issued on April 14, 1978 and later amended on Jan. 18, 1979.

If any deviations exist, identify and justify the deviations.

4.

Provide all the loading combinations used in the design of the pool structure, and the racks. An acceptable position is stated in Standard Review Plans 3.8 and the NRC position on fuel pools.

5.

-Discuss in detail the assumptions and method of analysis used in the design of the pool and racks. State which codes and standards are used in the design of the pool structure and the racks.

'6.

Provide a step by step general discussion on the seismic analysis of the pool and the racks.

The effect of three earthquake components should be considered.

7.

Indicate whether the leak tightness of the pool is a design criteria under all postulated loading combinations.

If this is the case, provide your methods for maintaining the leak tight integrity of the pool.
