Inspection Report 70-1100/79-03

'j Gentlemen:
During a recent inspection by NRC Region I, an item of noncompliance regarding uranium contamination smear surveys was identified.
In the inspection report, it was mentioned that Section 15 of our license apolication states that " a removable beta level of 5000 dpm/100 cm2 requires clean-up within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> in restricted areas and that a maximum removable bei.a level of 200 dpm/100 cm2 is permitted in clean areas". The inspector noted that surface contamination sur-veys to determine the beta contamination levels in restricted areas or clean areas are not performed.
While it is recognized that removable uranium may be detected by surveying for either alpha or beta surface contamination, we believe that alpha surveys are biologically more restrictive and relate more directly to potential personnel hazards.
It is requested that SNM-1067 be amended to reflect the fact that re-movable uranium will be surveyed by alpha detection only. Accordingly, it is requested that Page XV-6 Revision 3 dated 3/15/74 be replaced by the correspond-ing revised page dated 9/21/79.
The proposed license change contained in this application is considered to be an /
administrative type change as defined in 10 CFR 170.31 and the required fee of
$150.00 is being forwarded directly to the License Fee fianagement Branch under separate cover.
Very truly yours,

'.I 15.3.4 Health Physics Restricted Areas A Health Physics Restricted Area is an area in which more 235 than 350 grams of U as unclad U0 ay be processed, and/or in 2
which the radiation level exceeds 2.5 mr/hr. A removable alpha 2
1evel of 5000 dpm/100 cm requires clean-up within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, and 2
a level of 10,000 dpm/100 cm requires inmediate clean-up.
15.3.5 A Clean Area is an area which is free of radioactive contamination or ionizing radiation levels significantly grer+
thar background.
No radioactive contaminated equipment or clothing will be brought into a Clean Area unless authorized by the Radiological Safety Officer or the Nuclear Licensing and Safety Supervisor.
2 A maximum removable alpha level of 100 dpm/100 cm is permitted.
