SUBJECT:
EVALUATION OF WESTINGHOUSE-COLUt.BIA REQUEST - INTERIM RELIEF FROM 10 CFR 70.51(e)(3)
In a March 27, 1979 telecopy a request for a 21 day extension.
from April 28, 1979 to on or before May 19, 1979, was made to begin their physical inventory for low enriched uranium. The delay is to allow additional time to:
1.
Reprocess (re-blend, re-sample, re-weigh, re-analyze and tamper-safe) approximately 2,400 polypaks in storage that have not been previously tamper-safed.
This material is as described in the attached March 14, 1979 Tel ecopy.
2.
Blend off-stream SNM to measurable homogeneous forms for better accuracy and a beneficial effect on an overall lower LEMUF.
The licensee has made only one other such request - for their March 1978 inventory. That request was largely at the urging of I&E Region Office II so that Westinghouse-Columbia could have additional time to complete detailed inventory procedures needed to allow for a more organized-meaningful inventory (see my memo of March 3,1978).
I consider the licensee's current request reasonable and recommend approval.

Interim Relief From 10 CFR 70.51(e)(3)
Attachment Addendum In a March 27, 1979 telecopy a request for a 21 day extension was made to begin their low enriched uranium physical inventory.
As part of a generic study concerning LEU inventory practices, additional information in regards to the primary reason for the delay request was obtained in a telecon with John Chinault, QC Engineer, Westinghouse-Columbia on 3/29/79.
The 21 day delay was necessitated by the excessive oxidation of 2,400 polypaks of product U02 and U 038 that was not able to be put into the product stream as quickly as had been anticipated. The inventory delay, from April 28,1979 to May 19,1979 is to allow for the reprocessing (re-blend, re-sample, re-weigh, re-analyze and tamper-safing) of the 2,400 polypaks in storage that have not been previously tamper-safed.
Details are as follows:
aks V 8 ebe ing
- a blend mixture will consist of 60 to 113 polypaks
- material is stratified - blended
- material is dumped back into the polypaks polypaks are immediately weighed and sealed an overcheck scan (SAM II) of the polypaks for U-235 is made QC is notified ar.d requested to perform analytical services QC breaks seals on (4) randomly selected polypaks
- (3) thief semples, from each of the (4) randomly selected polypaks, are taken and blended for verification of blend analyses and U-/U-235 content
- Sampling plan is stated by Westinghouse to be at the 95". confidence level
- Each polypak contains approximately -
UO2 or U108 Net Element Isotope 18.0 Kgs 16.0 Kgs 0.45 Kgs CC
