§197.26. What are the circumstances of the human intrusion?

40 C.F.R. § 197.26

For the purposes of the analysis of human intrusion, DOE must make the following assumptions:
(a)
There is a single human intrusion as a result of exploratory drilling for ground water;
(b)
The intruders drill a borehole directly through a degraded waste package into the uppermost aquifer underlying the Yucca Mountain repository;
(c)
The drillers use the common techniques and practices that are currently employed in exploratory drilling for ground water in the region surrounding Yucca Mountain;
(d)
Careful sealing of the borehole does not occur, instead natural degradation processes gradually modify the borehole;
(e)
Only releases of radionuclides that occur as a result of the intrusion and that are transported through the resulting borehole to the saturated zone are projected; and
(f)
No releases are included which are caused by unlikely natural processes and events.
