'SGLB:SSK 70-1151 Westinghouse Electric Corporation Nuclear' Fuel Division ATIN: Mr. C. F. Sanders, Manager Nuclear Materials Management i
Drawer R Columbia, South Carolina 29205 Gentlemen:
l 1
This is to. correct some discrepancies in our letter of June 5,1987, as discussed between your Mr. R. Williams and Mr. S. S. Kirslis of my staff on
' June 16,1987. The following replaces that letter in its entirety, and responds to your: letter LA 87-14 and attachment dated April 1,1987 in which you requested exemptions from the requirements of the Columbia Plant FNMC Plan for three activities related to safeguards. The first request was for permission to use nominal tare weights in calculating the small amount of uranium-(a total. U-235 content less than 70 grams) in seven Model 8A UF 6 cylinders being shipped to NFS for~ cleaning in preparation for re-certification.
The weight of uranium recorded on DOE /NRC Form 741 would be corrected after the wash solutions were analyzed by NFS.
Your second request was for our approval of your plan to prepare two analytical control standards in-house to replace the NBL120 standard (U0 powder), which is no longer available for purchase. Ti > UO control stabdard 9
for the gravimetric uranium analysis would be a selectu batch of 500 J
well-characterized sintered U0 pellets from Operations.
The control standard for the titration method of ur$nium analysis would be'a uranyl nitrate solution prepared from a clean UNH solution from your Conversion process.
The uranium content of each standard would be calibrated against 4; certified standard such as NBL120 either by two independent analytical methods in the same laboratory or by the same method in two independent laboratories.
1 L
Your third request was for approval of the use of a single standard control program for.the new higher quality tube. scales to be.used in the ADU process
. lines.
At present, eight weight standards are used to assure bias-free point-calibration of the old tube scales over the range of 200 to 700 grams.
The.linearity and reproducibility of the new state-of-the-art scales will be initially demonstrated. A monthly calibration of the new scales to verify their linearity of resp'onse with at least four traceable standards covering the range of use would assure an adequate reliability, of the same order as the previous bios-free point-calibration with eight standards.
We have reviewed these requests and have determined that the granting of your requests, as modified in the following license conditions, is warranted, and will not adversely affect the common defense and security nor the public l
health and safety, and is otherwise in the public interest. Accordingly, we b

Mr. C. F. Sanders O 26 %
dre hereby granting exemptions to the requirements of Sections 6.2.3, 4.1.1 end 4.2.2 of the Columbia Plent FNMC Plan ~, by issuing three numbered license conditions to Amendment SG-3 of your License No. SNM-1107, effective immediately, to read as follows:
License Condition 1.5:
Notwithstanding the requirernents of the FNMC Plan identified in Condition 2.1, the. licensee moy prepore in-house analytical control standards for use in the gravimetric ond titration methods of uranium analysis as described in the ottachment to letter 87-14 deted April 1, 1987. The uranium content of the U0,3 standard and of the uranyl nitrdte standard will be determined in each case by analyzing 15 samples by each of two independent laboratories or by each of two independent andlytical methods in the same laboratory.
Each of the andlytical methods used to establish the assigned % U values of the control standards shall be calibrated against nationally accepted standards.
License Conuition 1.6:
Notwit!' standing the requirements of the FNMC Plan identified in Condition 2.1, the licensee may use a single stendard control program for the new linear-response tube scales to be used in the ADU process lines as described in the attachment to letter 87-14 dated April 1,1987, provided (1) that the single standdr" system is initially demonstrated to be as bids-free as the point-calibration system, and (2) thdt the continued linearity of response of the new tube scoles is verified by monthly calibration against at least four traceable standards covering the range of use.
License Condition 1.7:
Notwithstanding the requirements of the FNMC Plan identified in Condition 2.1, tne licensee may use on DOE /NRC Form 741 a nominal tare weight of 80.285 kg for each of the 7 cylinders identified in the attachment to 4
I letter LA 87-14 dated April 1, 1987.
This condition will expire on August 31, 1987 when the uranium content of the identified cylinders has been determined and used to adjust the DOE /NRC FORM 741 values.
The modifications to your requests incorporated in License Conditions 1.5 and 1.6 were discussed between our Mr. S. S. Kirslis and Mr. Dan Colwell of your staff.
It is our understanding that the modified license conditions are i
dCCeptable to you dnd Will be included in your FNMC Plan.
