                   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.  197.25  What standard must DOE meet?



    The DOE must determine the earliest time after disposal that the 

waste package would degrade sufficiently that a human intrusion (see 

Sec.  197.26) could occur without recognition by the drillers. The DOE 

must:

    (a) If complete waste package penetration is projected to occur at 

or before 10,000 years after disposal:

    (1) Demonstrate that there is a reasonable expectation that the 

reasonably maximally exposed individual receives no more than an annual 

committed effective dose equivalent of 150 microsieverts (15 millirems) 

as a result of a human intrusion, at or before 10,000 years after 

disposal. The analysis must include all potential environmental pathways 

of radionuclide transport and exposure; and

    (2) If exposures to the reasonably maximally exposed individual 

occur more than 10,000 years after disposal, include the results of the 

analysis and its bases in the environmental impact statement for Yucca 

Mountain as an indicator of long-term disposal system performance; and

    (b) Include the results of the analysis and its bases in the 

environmental impact statement for Yucca Mountain as an indicator of 

long-term disposal system performance, if the intrusion is not projected 

to occur before 10,000 years after disposal.
