September 16,.1987-The Honorable Lando W.= Zech,- Jr.
Chairman U.S. Nuclear Regulatory Commission Washington, D.C. 20555
Dear Chairman Zech:
SUBJECT:
ACRS COMMENTS ON DEVELOPMENTS IN' EMERGENCY PLANNING-1 10-12, 1987, we met with During the 329th meeting of the ACRS, September representatives of the New York Power Authority, the Oak. Ridge Associ--
ated Universities, and the Sandia National Laboratories to discuss prelimina ry analyses of the benefits of various ~ measures -taken to protect the. population in case of' a major, accident at a nuclear power-plant, ' Representatives of the NRC Staff took part in the discussion.
l This matter was also the subject of a' meeting of our Subcommittee on-Occupational and Environmental Radiation protection Systems held on1 June-i 22-23' 1987.
Studies reported by these groups indicate that sheltering, followed by monitoring of radiation exposure rates and relocation. of -populations -
from affected high radiation areas, within 4 to'8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> after an'acci-dent, yields predictions for the number of prompt fatalities lower than-
~
those estimated to be provided by the evacuation expected:under current I
decision-making practices.
This was the. statistical result of a. wide i
range of accident scenarios.
Since the number of people, the distance they would need to be moved, and the disruptive impact of the sheltering--
relocation approach would normally be less than those-for the immediate
'3 evacuation approach, we believe that the NRC Staff should be ! asked to j
conduct an independent and prompt assessment of these findings.. Should this assessment confirm the reported observations, there' appears to be reason for emphasizing sheltering, where appropriate, in nuclear emer-gency response.
Sincerely,
'l William Kerr j
Chairman
