The Honorable James E. Risch United States Senator

Twin Falls, ID 83301

Dear Senator Risch:

Without success, I have been trying to get documents from the NRC in the arena of hardened venting systems such as would apply to Idaho’s neighboring Columbia Generating Station and other boiling water nuclear power reactors.

Here is what I need:

On page 33 of 36 of reference ML13143A321, I read:
1.2 The HCVS shall include the following design features:
1.2.1 The HCVS shall have the capacity to vent the steam/energy equivalent of 1 percent of iicensed/rated thermal power (unless a lower value is justified by analyses), and be able to maintain containment pressure below the primary containment design pressure.

I need the list of references that document the basis for 1.2.1. This request is specific, concise and vital. Please tell NRC to respond promptly with the list of references.



Robert H. Leyse
