ATTN: Mr. R. Gregg Plant Manager One Narragansett Trail Wood River Junction, Rhode Island 02894 Gentlemen:
This is in response to your letter dated February 27, 1981, which transmitted a description of your proposed procedure for detemining the special nuclear material content of concrete and floor tiles.
We have determined that your proposed procedure is acceptable provided the additional comitment involving enrichment detemination, agreed to by Mr. L'Heureux during a March 13 telecon, is applied.
It is our under-standing that each of the five samoles for isotopic detemination will be a composite representing on the order of six to seven individual sampling points. The average enrichment deternined from this characterization study may be used for all concrete and floor tile, or the average enrichment for all cleanout materials may be used provided a test of the means demonstrates no significant differences. We request that you submit a confirmation to the effect that the understanding cited above will be the actual case.
From discussions with members of your staff, we also understand that there may be some consideration given to mechanically abrading or chipping away l
of concrete and block surfaces.
If this is the case, representative l
standards, which take into account matrix and geometry variations, would be required.
Sincerely, m
l Ioert A. Erickson, Acting Chief Material Control and Accountability Licensing Branch l
