                   TITLE 40--PROTECTION OF ENVIRONMENT

 

         CHAPTER I--ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)

 

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.  197.14  What is a reasonable expectation?



    Reasonable expectation means that NRC is satisfied that compliance 

will be achieved based upon the full record before it. Characteristics 

of reasonable expectation include that it:

    (a) Requires less than absolute proof because absolute proof is 

impossible to attain for disposal due to the uncertainty of projecting 

long-term performance;

    (b) Accounts for the inherently greater uncertainties in making 

long-term projections of the performance of the Yucca Mountain disposal 

system;

    (c) Does not exclude important parameters from assessments and 

analyses simply because they are difficult to precisely quantify to a 

high degree of confidence; and

    (d) Focuses performance assessments and analyses upon the full range 

of defensible and reasonable parameter distributions rather than only 

upon extreme physical situations and parameter values.
