Dear John,

This letter is in response to your telephone request of sluly 30,1980 for UCLA's Quality Assurance Program, Handling Procedures and written answers to your health physics questions. Please find the xerox copies of items 1 and 2 enclosed.

The health physics procedures and monitoring, for which data is a' v ailable in this facility for inspection by authorized individuals, is summarized in the following paragraphs.

~

The truck and cask _ was thoroughly monitored upon arrival at UCLA both by thin

.end window GM and swipe tests. The cask truck bed top-surface, and plywood sheet, showed no rerravable contamination. The cask frames and lids were set down on decon paper on the truck bed and a swipi ~of the inside of the cask showed trace amounts of Cesium-137. This removable contamination was approximately in the range of 4.7 x10 6 pCi/cm2 , and did not pose a contamination problem. Since the reactor fuel'is composed of Uranium Aluminum cutec'ttic clad in pure Aluminum and bolted together with Aluminum bolts, no Cobalt-69 was anticipated. The bottom of the truck bed was not monitored because there was no obvious need.

ThE fuel was transferred in Aluminum tubes surrounded by lead and placed in an intemediate cask filled with L.A. city drinking water for shielding. This cask was fabricated for this transfer and had never been used before or since for radioac'tive materials. This cask was also swipe tested at the conclusion of this e operation and found to be background on the inside walls and bottom.

When the fuel was actually transferred into the GE cask on the trailer, it was allowed to drip dry prior to placing it into the GE cask. All areas where water dripped were swiped, dried under special heat lamps and counted, and were found to be background.

All personnel, including the Tri State driver were required and did submit to EWGM checks of their hands, gloves and shoe bottoms prior to their leaving the

. trailer bed each time they left it.

At the conclusion of the operation, the trailer bed, cask, area, personnel, gloves and associated tools and hardward were surveyed with the EWGM and swipe tested. No activity was found. .

scnoot.or acistemc Aso Arruco sciExcE LDS ANCELL5 CAUTORN14 luS4 The shipping documents list the top of the cask under the internal cover as less -

than 200 dpm alpha, beta, gamma and background for the entire outside. ' , ,

There was some painted in contamination found on the left side of the base which read 50 mR/ hour at contact but background based on swipe tests. .

This concludes our radiation monitoring except to say the committed dose to individuals was less than 5 mR total body with no contamination.

- After learning of the contamination from GE, all paper, rags, girees, and hardward were recovered and surveyed in great detail. . Cotton gloves were worn by personnel working on the truck and cask. One of the eight gloves was found to have activity slightly above background. Gamma spectrum analyses by UCLA, and indepen'd ently by Uranium west, indicated Cesium-137 and Cobalt-60 in approximately equal proportions. The combined activity was approximately 3 x 10 NCi or 11 -

disintegrations per second. This is approximately 0.6% of the 100,000 cpm verbally indicated to us by General Electric.

No other contaminated materials were found. Personnel and gloves were rotated during the operation, there is no way to determine which individual encountered .

.the material nor where the material was encountered. ,

-Our laboratory neither possesses nor uses any open or unsealed Cobalt-60 '

sources.

Yours truly, t

O.
