Taking into consideration 18 and 24 month fuel cycles, do any stations allow 
longer periods between 10CFR61 updates greater than the suggested annual update 
for Cass B/C  waste and biennial update for Class A waste?

(The NRC Branch Technical Position on waste classification 5/11/1983 does allow 
for analysis extensions greater than two years for Waste Class A and greater 
than one year for Waste Class B or C.)
