PART 197_PUBLIC HEALTH AND ENVIRONMENTAL RADIATION PROTECTION STANDARDS 

FOR YUCCA MOUNTAIN, NEVADA--Table of Contents

 

    Subpart B_Public Health and Environmental Standards for Disposal

 

Sec.  197.36  Are there limits on what DOE must consider in the 

performance assessments?



    Yes. The DOE's performance assessments shall not include 

consideration of very unlikely features, events, or processes, i.e., 

those that are estimated to have less than one chance in 10,000 of 

occurring within 10,000 years of disposal. The NRC shall exclude 

unlikely features, events, and processes, or sequences of events and 

processes from the assessments for the human intrusion and ground water 

protection standards. The specific probability of the unlikely features, 

events, and processes is to be specified by NRC. In addition, unless 

otherwise specified in NRC regulations, DOE's performance assessments 

need not evaluate, the impacts resulting from any features, events, and 

processes or sequences of events and processes with a higher chance of 

occurrence if the results of the performance assessments would not be 

changed significantly.
