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.
