Storage of Low Level Wastes At Power Reactor Sites NRC Docket Nos. 50-295 and 304 References (a):
Standard Review Plan - NUREG 0800, Rev. 2, dated July 2, 1981.
(b):
Letter and Guidance Paper from W. J. Dirks to All Licensees, dated November 10, 1981.
Dear Mr. Denton:
The referenced documents list generally acceptable guidelines for the design of low level waste storage facilities at power reactor sites.
This is to request additional clarification and elaboration o f the NRC's position.
Specifically, we have questions regarding two items that could have significant impact upon. facility design:
1.
The recommended site boundary dose rate is 1 mrem /yr.
Is this considered an absolute maximum?
If not, what technical support would be required to raise the acceptable dose rate?
Is there a threshold value above which installation of the f acility would be considered an unreviewed safety question?
2.
As a minimum, a quarterly container inspection program is recommended.
What percentage of the containers must be inspected at each inspection interval?
Is the inspection interval dependent upon container stack height (i.e., load on the base container)?
Is there a limit on a stack height?
Commonwealth Edison is currently reviewing proposed designs for such facilities.
Resolution of these items is needed if our review is to result in a f acility design that meets our storage 00
