Dear Mr. Wassel:

SUBJECT:
SUPPLEMENTAL INFORMATION ON THE DOSE VS. RELEASE CALCULATIONS i
PRESENTED AT THE NOVEMBER MEETING 0F THE COMMITTEE ON TECHNICAL BASES FOR YUCCA MOUNTAIN STANDARDS During the presentation by Dr. Norman Eisenberg, a member of my staff, at the l
November meeting of the Committee on Technical Bases for Yucca Mountain Standards, questions were raised regarding the relative impact of different radionuclides due to drilling events.
I am enclosing a brief analysis of the calculations used to obtain the results that were presented. Also enclosed is a brief response to questions raised about the relationship of undisturbed and i
disturbed repository performance. This information, I believe, should be
{
sufficient to answer the questions posed by the Committee. Also, I am i
enclosing a revised copy of the transparencies used during the presentation.
t i
A report on the use of institutional controls to protect waste disposal sites-
[
from inadvertent intrusion has recently become publicly available.
I am i
l enclosing eight copies of this report, SECY-93-322, for use by the Committee.
i f
i I hope that the information provided here will be useful to the Committee and will facilitate its deliberations.
Sincerely, k
l i
i Margaret V. Federline, Chief I
Hydrology and Systems Performance Branch Division of High-Level Waste Management, NMSS
