Dear Sir:

In a letter sent to the Document Control Desk of the USNRC, dated December 21,1993, the Washington State University TRIGA reactor facility (License No R-76), in acetrdance with the arovisions of the Code of Federal Regulations section 50.54(q), ma,le a request to amend its 3rnergency Plan. In a letter dated Friday, May 13,1994 we proposed some additional changes.

On June 27 28,1994,in telephone conversations with Marvin Mendonca, it was agreed that both the old terminology, MPC (Maximum Permissible Concentration) and DAC-hours (Derived Air Concentration - hours) were no longer appropriate measures of various emergency levels. There is a consensus that the emergency levels are fundamentally related to a limitation on whole lxxly dose. We therefore concur with the US NRC that simply removing the references to MPC and leaving the action level expressed as a whole body dose accumulated in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> as adequate and sufficient. We therefore wenld like to include removal of the four references to MPC o: JAC-hours in this latest revision, in order for our " Assessment Actions" on page 27, Section 7.3.1 b) to confonn to the elimination of MPC we are converting our CAM reading into an estimate of whole bcxiy dose that would be accumulated in 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

Please find enclosed a draft of the Emergency Prcparedness Plan that includes all of the proposed revisions including the four references to MPC (or DAC-hours) discussed in the June 27 28 i telephone discussions.

If you have any questions, please contact Dr. Gerald Tripard, Facility Director (509) 335-0172 Sincerel{,
