The purpose of this letter.
request approval of modifications to License SNM-777, reflecting the continued progress of decommissioning of this facility.
The requested changes, which are detailed in the attachments to this letter, involve a deletion of nuclear alarm requirements and c
a modification to the requirements for on-site coverage by a nuclear criticality specialist.
Both of these changes are directly associated with the reduction in the SNM inventory at this site and the form and concentration of the SNM which remains.
As this amendment would have no significant safety, environ-mental, or safeguards impact, we consider it to be adminis-trative in nature and have included a check for the required
$150 fee.
If you have any questions regarding these changes, please contact K.
Helgeson or myself.

ATTACEMENT TO LETTER RJG: 81-68, DATED APRIL 24, 1981 R. J. Gregg to W. T. Crow UNC Recovery Systems respectfully requests that License SNM '/77 be amended to eliminate Section 405.1 which describes the requirements for nuclear criticality alarms.
In addition, exemption from the requirements of Section 70.24 of 10 CFR Part 70 is requested.
In conjunction with relief fro.n the above specified require-ments, UNC requests approval of a change to Section 202.3 of our license, to require the services of a nuclear criticality specialist only on an "as needed" basis instead of "a minimum of one work day on site during each two-week period of regularly scheduled plant operation."
At the present stage of site decommissioning, the remaining discrete quantities of U-235 exist as less than 200 grams of U-235 in the form of gamma counting standards.
Other on-site SNM material is primarily in the form of lagoon sludge, either in the lagoon awaiting solidification, or packaged for burial, with an average concentration of approximately 0.00004 grams of U-235 per gram of lagoon material.
- Also, approximately 1.2 kgs of U-235 is in the form of solidified organics (thirty-two 55 gal. drums) and raschig rings (twenty 55 gal. drums) awaiting shipment to burial.
The maximum content of any of these 52 drums is less than 37 grams of U-235.
All other SNM material exists in the form of contamination of building surfaces, ductwcrk, etc.
A comprehensive Beta-Gamma survey of the facility has shown no significant accumulations of radioactive materials.
The facility has also been inspected by the NRC for discrete quantities of SNM, prior to approval l
of reductions in security requirements. (Rererence letter, Robert F.
Burnett to Robert J. Gregg, dated April 9, 1981).
The facility as per Section 70.24 of 10 CFR Part 70 and Paragraph 4.2.1 of ANSI /ANS Standard 8.3-1979, has been evaluated and it has been determined that the remaining quantities and forms of special nuclear material on site make criticality " practically impossible".
Therefore, this l
request is in keeping with the discussion and regulatory l
position stated in Regulatory Guide 8.12, Rev. 1, dated January, 1981.

Assignment of the individual shall be approved by at least two levels of manegement above this position.
Minimum re-quirements for this position shall include at least ten years experience in a responsible position in the nuclear industry, with at least three years in an activity wherein he has per-formed safety evaluations in either criticality or radic-logical safety and has developed an understanding of ?ia dis-ciplines under his management.
Any individual having responsibility for technical evaluations or review of a safety aspect (Health Physics, Criticality) shall hold at least a B.S. degree in Science or Engineering and possess not less than three years responsible experience in the nuclear field, with a t least one year in the perfor-mance of such safety assessments in the area of his speciality.
Assignment to evaluation or review responsibilities requires in addition, demonstration of proficiency in the specialty to the Manager, NIS.
Consultants, when assigned responsibilities for evaluation or review, shall meet the above requirements in the area of the specialty involved.
When Health Physics consultants are used on a regular basis to perform evaluations and reviews in lieu of full time employees, they shall be required to spend a minimum of one work day on site during each two-week period of regu-larly scheduled plant operation.
This frequency may vary, how-ever, for such occasions as plant shutdowns, holiday periods, personnel vacations, or company-approved personnel absences.
