published a direct final rule amending its regulations at 10 CFR 72.214

Combustion Engineering 16x16 class fuel assemblies as authorized 
contents; reduce the minimum off-normal ambient temperature from -20 
[deg]F to -21 [deg]F; expand the authorized contents of the 
NUHOMS[supreg] HD System to include pressurized water reactor fuel 
assemblies with control components; reduce the minimum initial 
enrichment of fuel assemblies from 1.5 weight percent uranium-235 to 
0.2 weight percent uranium-235; clarify the requirements of 
reconstituted fuel assemblies; add requirements to qualify metal matrix 
composite neutron absorbers with integral aluminum cladding; clarify 
the requirements for neutron absorber tests; delete use of nitrogen for 
draining the water from the dry shielded canister (DSC), and allow only 
helium as a cover gas during DSC cavity water removal operations; and 
make corresponding changes to the technical specifications. In the 
direct final rule, NRC stated that if no significant adverse comments 
were received, the direct final rule would become final on March 29, 
    The NRC did not receive any comments on the direct final rule. 
Therefore, this rule will become effective as scheduled.
