SUBJECT:
DETERMINATION OF REPRESENTATIVENESS OF AIR SAMPLING -
WESTINGH0USE NUCLEAR FUEL DIVISION (70-1151)
License Condition 9 of License SNM-1107 for the Westinghouse Nuclear Fuel Plant at Columbia, SC requires that materials be used in accordance with statements, representations, and conditions contained in Chapters 2, 3, and 4 of the application.
Section 2.2.6.3 of the application requires that " Air sampling representa).iveness of existing fixed samplers shall be performed..."
A frequency of one year or two years is specified, depending on average concentration.
Section 2.2.6.3 requires that the (representativeness) studies shall "use appropriate air sampling techniques."
The license application does not define what " appropriate air sampling techniques" are to be used nor does it specify the acceptance criteria.
By comparison, the application for Nuclear Fuel Services requires that the representativeness of fixed air samplers be verified using lapel air samplers and that the results be within a factor of 2.
During a recent inspection, Westinghouse expressed a concern that the NRC has not provided any guidance on how to meet this license condition, e.g. appropriate techniques for determining representativeness of air samplers and acceptance criteria.
In your memorandum to K. P. Barr of October 26, 1984, responding to Region II concerns on the renewal of Westinghouse's SNM license, you indicated that it was not appropriate to specify in the license a specific technique for determining the representativeness of air sampling.
You also indicated that the adequacy of the techniques used should be determined by the inspector.
However, in light of the continuing concern by licensees and the Regional staff about the appropriate methods to be used and the acceptance criteria, we request that you provide us your position regarding what constitutes " appropriate air sampling techniques" and what your position is regarding the appropriate acceptance criteria. We are not aware of acceptance criteria other than that defined in the NFS license. We suggest that these positions be documented as a Branch Technical Position so that Westinghouse and other licensees have this guidance available to them, h
