Fuel cycle facilities regulated under Part 70 of Title 10 of the Code of Federal Regulations (10 CFR), Subpart H, are required to submit ISA summaries which include ‘‘proposed quantitative standards’’ as required by 10 CFR 70.65(b)(7). These standards are used to determine when acute chemical exposure events analyzed in the ISA result in high or intermediate consequences as defined in 10 CFR 70.61. In ISAs that the NRC staff reviewed prior to 2008, the staff evaluated licensee-proposed standards identifying high and intermediate acute uranium exposure events. Some licensees proposed 40 milligram (mg) uranium intake for defining high consequence events based on International Commission on Radiological Protection (ICRP) methodology while other licensees proposed 75 mg uranium intake based in ICRP 68 methodology. Both were accepted by the NRC staff for use in the licensee’s ISAs. All licensees proposed 30 mg uranium for defining intermediate consequence events which were accepted by the staff. In December 2008, the Nuclear Energy Institute (NEI) submitted a report on acute uranium toxicity and requested that the NRC consider the uranium toxicity information in the report and provides guidance on uranium exposure standards that can be used in facility ISAs. The NRC staff reviewed the original NEI report and a revised version submitted in 2009 and also conducted an independent technical review of information on the chemical toxicity of uranium. The NRC staff found particularly useful information on acute uranium toxicity in studies conducted by the Royal Society and the U.S. Army, and the National Research Council review of the U.S. Army study. This information provided a basis for the staff identification of uranium renal concentrations that are expected to lead to physiological effects comparable to those described as high and intermediate in 10 CFR 70.61. Based on its review of the uranium toxicity literature, including the NEI reports, NRC staff has identified acute uranium intake quantities that it considers acceptable for classifying acute worker uranium exposure events analyzed in ISAs as either high or intermediate consistent with the definitions in 10 CFR 70.61. These quantities are identified in the interim staff guidance.

acute chemical exposure events analyzed in the ISA result in high or 
intermediate consequences. The NRC has developed an ISG document that 
identifies uranium intake quantities the staff finds acceptable for 
classifying uranium exposure events analyzed in ISAs.

DATES: Submit comments by December 1, 2014. Comments received after 
this date will be considered if it is practical to do so, but the 
Commission is able to ensure consideration only for comments received 
before this date.

II. Background.

    Fuel cycle facilities regulated under Part 70 of Title 10 of the 
Code of Federal Regulations (10 CFR), Subpart H, are required to submit 
ISA summaries which include ``proposed quantitative standards'' as 
required by 10 CFR 70.65(b)(7). These standards are used to determine 
when acute chemical exposure events analyzed in the ISA result in high 
or intermediate consequences as defined in 10 CFR 70.61.

evaluated licensee-proposed standards identifying high and intermediate 
acute uranium exposure events. Some licensees proposed 40 milligram 
(mg) uranium intake for defining high consequence events based on 
International Commission on Radiological Protection (ICRP) methodology 
while other licensees proposed 75 mg uranium intake based in ICRP 68 
methodology. Both were accepted by the NRC staff for use in the
