SUPPLEMENTARY REPORT ON SHOREHAM NUCLEAR POWER STATION UNIT 1
Dear Dr. Seaborg:
4 At.its 125th meeting, September 17-19, 1970, the. Advisory Conunittee on Reactor Safeguards considered possible adverse effects of a nearby Nike Hercules battery.on the safety of the proposed Shoreham Nuclear Power Station Unit 1 of the Long Island Lighting Company. This matter was also considered at Subcommittee meetings on October 30, 1969 at che' site and on September 10, 1970, in Washington, D. C.
The Shoreham project was the subject of previous Committee reports to you dated. December 18,
]
1969 and February 11, 1970. During its present review the Committee had the benefit of discussions with representatives and consultants.of, the Long Island Lighting Company, The General Electric Company, The Stone and Webster. Engineering Corporation, the Department of Defense, and the AEC Regulatory Staff, and of the document listed.
The launching area of the Nike Hercules battery is located about 1.4 miles from the Shoreham reactor. The battery control area is about 0.7 miles from the reactor. The missile launchers have a fixed direction, i
not toward the site, and missiles accidentally launched with guidance control would not pass over the site. Further, the maneuvering limita-tions.of the Nike Hercules are such that a missile under guidance control could not be turned to impact in the site area without breaking up in the air.
The Nike Hercules battery is located far enough' from the Shoreham site so that the detonation of all high explosive at the battery would not cause significant damage to the proposed reactor facility.
In the unlikely event of an accidental launching of a missile there would be no guidance control and the missile would break up soon after launching. The resulting fragments, including the warhead, would be distributed over the ground area within several miles of the launching 1
position.

.M Honorable Glenn'T. Seaborg September 23, 1970 l'
-The likelihood of a missile fragment striking the Shoreham plant area and causing significant damage due to impact or explosion is a combination j
of the probability of a launch which results in breakup of the missile l
and the probability, given such a breakup, that d'1arge. fragment strikes
)
a sensitive portion of the plant. The Committee believes that the overall probability of significant damage to the proposed plant.from the Nike Hercules battery is so small that it does not detract from the accept-ability of the site for the proposed plant.
The Committee recommends that the Regulatory Staff make arrangements with-the Department of Defense to be notified of any contemplated changes in 1
the Nike Hercules installation in the Shoreham area which might change i
the' present evaluation of the likelihood of damage to the reactor facility.
These arrangements should be completed.before power operation of the j
reactor.
The Committee believes that if due consideration is given to the items described in the previous reports, the nuclear plant proposed for the Shoreham Station can be constructed with readonable assurance that it can be operated without undue risk to the health and safety of the public.
i Sincerely your *,
