This supplemental testimony is offered in response to Stipulated 2
Contention 9 of Columbia County Survival Committee and Arthur L. Reuter, 3
which reads:
4 Contention 9 5
Petitioner contends that accidental radiological releases from the 6
proposed Greer.e County Nuclear Power Plant may result in damage to the 7
water supplies of New York City, Cementon, Catskill, Saugerties and 8
those Westchester comunities which depend upon the New York City 9
water supplies.
10 The proposed site is about 13 miles from Ashokan Reservoir of the 11 City of New York. Any impregnation of the reservoir by radioactive 12 substances could kill millions in New York City and suburban 13 communities which depend on New York City water.
14 The site also is in close proximity to the open-to-the-air water supplies 15 of Catskill and Saugerties and to the wells used by Cementon residents.
In Section 15.5.1 of SER Supplement 1 the Staff reported on its 16 review of the radiological consequences of the deposition of radionuclides 37 into the water supply reservoirs near the site after a postulated loss-18 f-coolant accident (the most severe accident required to be analyzed).
19 20 This supplemental testimony addresses two additional matters:
1) the 21 basis for concluding that appropriate protective actions could be undertaken with respect to the reservoirs within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> following 22 23 the postulated accident and 2) the effects of an accidental liquid radiological release from the Greene County Plant on wells used by 24 1

Cementon residents.
2 Reservoirs 3
In the event of an accident, immediate notification of off-site 4
officials would be made by the Power Authority of the State of New York.
5 The responsible officials would then have available to them the choice 6
of protective actions described on p. 12 of the New York State Plan 7
for Radiation Accidents (1-77 Revision). For the water pathway these
~
8 actions include: alert water supply operators, monitor and evaluate, sample water, restrict use of water to sanitary and firefighting 9
purposes as needed, and (in the most severe case) shut off the reservoir.
10 It was this spectrum that the Staff had in mind when it assumed in the l
11 SER that appropriate protective actions could be taken within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
12 13 Effects of Accidental Liquid Releases on Wells 1
14 This response addresses the effects of accidental liquid radio-15 logical releases front the proposed Greene County Plant on wells used 16 by Cementon residents. The effects of accidental radiological releases 37 have been discussed in Section 2.4.6 of the Safety Evaluation Report, the relevant portion of which is reproduced here for convenience.
18 The applicant analyzed the effects of an accidental spill of 39 radioactive liquids at the plant facility site. We performed 20 a similar independent analysis of this hypothesized event.
It g
was determined that the bounding event would be the failure of the 150,000 gallon boron recovery tank.
It was assumed that the spill from the tank would travel through the ground water 2
i I'
Larry W. Bell Gale P. Turi James A. Martin to the Hudson River. There are no wells downgradient of the 3
2 facility that could be affected by the spill. The spill was then assumed to travel the 17 miles downstream to the nearest 3
drinking water supply intake at Rhinebeck, New York. Our 4
evaluation of this event is given in Section 15.5.3'of this report.
5 6
The Safety Evaluation Report concluded (Section 15.5.3) that the above 7
postulated event would not result in concentrations of radionuclides in 8
excess of Title 10 CFR Part 20, Appendix B, Table II.
9 Cementon is located approximately one mile southwest of the proposed 10 site. Since Cementon is upgradient of the proposed site, groundwater 11 in the proposed site area and any radioactivity it might contain would 12 not travel toward Cementon. Therefore, the wells used by Cementon 13 residents could not be effected by accidental liquid radiological 14 releases from the proposed Greene County Plant.

i I am a Nuclear Engineer in the Accident Analysis Branch, Division of Site j
Safety and Environmental Analysis, Office of Nuclear Reactor Regulation, I
I U. S. Nuclear Regulatory Commission. My duties in this position '.nclude the evaluation of site related safety aspects of nuclear power generating f acil-ities and radiological asses ment of design basis accident consequences.
I received a B.S. degree in Physics f rom the L'niversity of Maryland in 1960 and M.S. degree in Physics from the University of Maryland in 1966.
Before joining the Commission, I was employed from June 1969 to August 1974 as an Aerospace Engineer with the National Aeronautics and Space Administration (NASA) at the Goddard Space Flight Center in Greenbelt, Maryland.
In this capacity, I performed analysis and large scale computer simulations of in-flight dynamic behavior of satellite components.
I was employed from June 1968 to June 1969 in private industry as an Aerospace Engineer performing the same type of work as for the National J
Aeronautics and Space Administration.
I was employed from June 1960 to June 1968 as a Research Physicist vith the l
U. S. Naval Ordnance Laboratory in Whiteoak, Maryland.
In this capacity, I performed analysis and computer simulations of underwater nuclear explosions.
This work included both radiological and mechanical effects resulting from N
]
4 underwater explosiens of nuclear devices.
I aise did analysis of radielegical effects of surface vid upper air e.xplosions.
I have written about 12 technical papers and received a Superior AcMevement Award for making an original contribution to the field of Fluid "echanics.
I have been a member of the Regulatory staff since August 1974, and have par-ticipated in the review of about 10 nuclear power plants.
