,f Amendment to the Annual Report on the Operations of the Washingten State University TRIGA Reactor Facility License R-76 for the reporting period of July 1,1983 to June 30, 1984.

Some of the personnel and environmental radiation exposure data was not available at the time the Annual Report was prepared. The complete radiation exposure sections are as follows:

Page 4, Section G, Table VI, Average Quarterly Reactor and Experimenter Staff Exposure.

May and June badge results were not included. Below is the completed Table VI:

Calendar year 1983 ALARA limits for closest offsite extended occupancy vs. background radiation exposure ratio was given in the Annual Report.

Below is the fiscal year data for the reporting period of July 1,1983 to June 30, 1984.

For the reporting period, the average background radiation level for sampling points 400 meters or greater from the facility was 18/uR/ day.

The average radiation level at the closest extended occupied area 380 meters away was 214 uR/ day which yields a ratio of exposure to background of 18.2%.

ALARA limit is 20% exposure ratio.
