070-2928 The Spect'al Nucle Material (SNM) License SNM-1873 for Watts Bar Nuclear Plant (WBN).. uni t 30, 1987. An extension to SNM-1873isnece(dwillexpireonSeptember i
sary because of construction delays.
l Therefore, we hereby request SNM-1873 be extended until September 30,.1992.
In addition, TVA hereby requests an amendment to its Special Nuclear Material Licenses SNM-1861 dated September 5, 1979, for Watts Bar Nuclear' Plant unit 1 and SNM-1873 dated February 17, 1981, for unit 2.
Our' applications were dated June 8, 1979, for unit 1 and May 13, 1980, for unit 2 and the supplements thereto.
These revisions involve the last paragraph of section 2.1, Radiation Control, in each license.
The paragraph presently reads as follows in both cases:
"All portable radiation survey instrumentation will'be calibrated at least quarterly using standardized. sources which are traceable to the National Bureau of Standards. All laboratory radiation instrumentation will be calibrated,using the standardized sources and voltage plateau curves run at least onceiper month."
WBN is requesting that the paragraph be reworded as follows:-
"All portable radiation survey instrumentation and-laboratory radiation instrumentation shall-be. calibrated at least semiannually using.
standardized source activities or radiation field intensity which are traceable-to the National Bureau of Standards.
These may. include derived or laboratory standards.
Voltage plateau curves will'be run annually on proportional counter systems and,'in addition, after each gas change a voltage plateau curve or a response to a check source will be completed."

. l AUS 241987 U.S. Nuclear Regulatory Commission Quarterly calibrations are overly restrictive and resource intensive.
Semiannual calibrations are more appropriate and are consistent with industry accepted practices (reference ANSI N323-1978, Regulatory Guide 4.15, and INPO Guidance 85-004).
Calibration standards have been clarified to be consistent with industry practice (reference ANSI N323-1978).
Voltage plateau curve criteria are being revised to be consistent with Regulatory Guide 4.15 and denote its applicability to the appropriate equipment.
These changes will not significantly alter the quality of the HBN Radiological Control program.
They do, however, provide clarity and flexibility.
He are requesting that these changes be implemented as soon as possible.
In accordance with 10 CFR Part 170.11(a)5, an amendment fee is not required.
If you have any questions regarding this, please telephone K. P. Parr of my staff at (615) 751-2681.
