.f ENCLOSURE ADDITIONAL COMMENTS / QUESTIONS ON CINTICHEM DECOMMISSIONING-PLAN 2.1.2.1 Radiation Work Permits should contain information concerning actual contamination and radiation levels present and stay time if appropriate.
2.1.2.2.2 Access Control Why not provide access controls at the actual contaminated area boundary (step off pad, friskers, etc.)?
2.1.2.2.3.b Contamination Control Enclosures What will be the requiced airflow velocity at openings (should be minimum 100 linear /teet/ minute)?
2.1.2.3 Dose Control Program Whole body counting should be capable of detecting uranium in addition to byproduct material.
2.1.2.4 ALARA Control Program does not address alpha contamination.
Table 3.3 Major Decommissioning work scope does not address a review of soil contamination throughout the site.
General Soil contamination may not be seen with an instrument -- counting
. Comment techniques will be reqJired.
3.3.1.33 Survey Structures Identify those structures which may need to be placed on
-demolition hold points (potentially contaminated).
3.3.2 Does not-describe the scarifying process.
6.3 Solid Radweste Does not identify contaminated soil as a waste stream (most of l
the defined volume should come from this waste stream).
l 6.7 Onsite Storage-of Waste Does not recognize that New York State may be shut off from the burial sites - no contingency. plan discussed.
7.0 Incorre'ct statement that residual'SNM will be covered under the byproduct-license.
SNM-639 remains active.
7.3.1
-Add a requirement that air samples will be taken continuously while handling potentially contaminated soil (air sampling-should be downwind of activity).
L 7.3.'1. d Area radiation monitors should be capable of observing less than 100 mR/hr.
7.5.d Should be Review and Approval.
' Table 7.1 Shauld TLG be TLD?
8.1.2 Unrestricted release criterie should meet Reg. Guide 1.86 or NYS 38.29 Table 5 criteria.
8.2.1.3 Survey sampling should meet the NUREG 2082 criteria.
Inside surfaces,'1 meter grid suggested. This is the grid size that will be uset during the NRC verification survey for NUREG 2082. Smear samples should be taken in 5 locations in each grid.. Background should not be subtracted from these survey readingt. Statement needed that no demolition will take place prior to verification by the NRC as appropriate.
8.2.3 Refer to branch technical position in Federal Register Notice 46 FR 52061, October 23, 1981, Disposal of Onsite Storage of Thorium or: Uranium Wastes from Past Operations,Section II, Item.1, for residual uranium and thorium in soil and to NYS 38.29 for other nuclides.
8.2.3.2 Where residual contamination is expected the grid size should be at most 25 feet by'25 feet.
