Dear Mr. Chairman:
I am writing to support the Union of Concerned Scientists-Riverkeeper Petition 2.206, submitted to the NRC oniSe-pt ier-8,72003, which requcests the immediate shutdown of the Indian Point nuclear power plant.
As I understand it, the major focus of this petition is the pumps in Indian Point's containment buildings that provide the primary source of coolant in case of a major pipe break at the reactors. A study prepared for the NRC by the Los Alamos National Laboratory concluded that that the chances of a reactor meltdown increase by nearly a factor of 100 at Indian Point because the plant's containment sumps are "almost certain" to be blocked with debris during an accident.
The Los Alamos study rejects the possibility that clogging in the event of a loss of coolant accident at Indian Point could be prevented by other safety measures.
"The indicated outcome is almost certain," the report said. "Consideration of all identified uncertainties has been made, and none has been found to have a credible effect on the outcome."
I therefore urge you to order the immediate shutdown of Indian Point and to require Entergy to fix this significant safety problem which poses a direct threat to public health and the environment.
Sincerely, udith E. Fletcher MUSE (Musicians Unite to Save the Environment) jfletcherlriverdale.edu 525 W. 238th St. Apt. Al Bronx, NY 10463 (718) 796-8223

Dear Mr. Chairmnan:

I am writing to urge the'U.S. Nuclear Regulatory Commission to order'ihe immediate shutdo;'n of the Indian Point nuclear power plant in accordance with the prymaiyrequest madein the September 8, 2003 petitio'nthai'"was submitted by the Union of Concerned Scientists and Riverke'eper, Inc. The focus of the UCS-Riverkeeper petition is the pumps in Indian Point's containment buildings that provide'the primary source of coolant in case of a major pipe break at the reactors.
If such a pipe break were to occur, hot water pouring from the system would instantly turn to steam, which would eventually condense in ahuge pool on the floor of the containment building. The sump pumps are designed to re-circulate the water back through the reactors to prevent a fuel meltdown and possible'release of radiation.
However, agency studies have found that the superheated steam could cause the'insulation to disintegrate and possibly clog the sump pumps. If that happened, the water could not'be re-'circulated' and a meltdown and subsequent radioactive release could occur. A' study prepared for the NRC by the Los Alamos National Laboratory concluded that that the chances of aireactor meltdown increase by nearly a factor of 100 at Indian Point because the plant's containment sumps are "almost certain" to be blocked with debris during an "accident.
The Los Alamos'study rejects the possibility that clogging in the event of a loss of coolant accident at Indian Point could be prevented by other safety measures. "The indicated outcome is almost certain,"
the report said. "Consideration of all identified uncertainties has been made, and none has been found to
