TVA reviewed criteria for acministrative cose li-its in :ce:erate and site :rocedures.
The only reference to a catly en:esuae limit was in regard to RWDs.
All TVA admiristrative ex:esure limits are celow NRC exposure limits specified in 10 CFR 20.101.
There have been no exposures at Sequoyah in excess of NR0 li-its.
$h vid an employee exceed or come close to a cuarterly en::sure limit, tre TVA :olicy is to find other work for the et:1cyte in n:nent:svre areas.
