E-M:/ Cook Nuclear Plant wants Different Accident Assumptions

AMERICAN ELECTRIC POWER'S COOK NUCLEAR PLANT NEAR BRIDGMAN WANTS
TO REVISE ITS ASSUMPTIONS ABOUT RADIATION RELEASES FOR MODELLING
DESIGN BASIS NUCLEAR PLANT ACCIDENT

IT ISN'T CLEAR FROM THE NOTICE WHETHER AEP IS PREDICTING A GREATER OR
LESSOR AMOUNT OF NUCLEAR PLANT ACCIDENT RELEASE
FROM A CORE MELTDOWN THAN WAS PREVIOUSLY INDICATED.

HOWEVER, THE FEDERAL REGULATION REQUIRES THAT EXPECTED EXPOSURES TO THE
PUBLIC ON THE EDGE OF THE "EXCLUSION ZONE" DURING AN ACCIDENT BE NO MORE
THAN 25 REM AND THAT PLANT EMPLOYEES IN THE CONTROL ROOM BE EXPOSED TO
NO MORE THAN 5 REM.

LIFETIME BACKGROUND RADIATION EXPOSURE IS SOMEWHERE AROUND 5 REM LIFETIME
OR ABOUT 170 MILLIREM PER YEAR.

[SET CYNIC MODE ON]

IF THE COOK PLANT EVER HAS A CORE MELTDOWN ACCIDENT, WE CAN PILE
CODE OF FEDERAL REGULATION BOOKS ALL AROUND US AND LIMIT OUR TOTAL
EXTERNAL RADIATION EXPOSURE....  OR, WE CAN STAND AT THE EDGE OF
THE "EXCLUSION ZONE" AND HOLD UP 10 CFR 50.67 AND SEE IF THE DRIFTING
CLOUD OF FISSION PRODUCTS WILL JUMP AROUND US.

YET, JUDGING BY THE U.S. HOUSE REPUBLICAN LEADERSHIP'S INSISTENCE OF
A NON-RECORDED VOICE VOTE YESTERDAY EXTENDING THE PRICE ANDERSON ACT,
WE KNOW THAT DENNIS HASTERT, TOM DELAY AND DICK ARMY WILL BE THERE
FOR US NEXT TO THE EXCLUSION ZONE AFTER AN ACCIDENT, REMINDING US
THAT THE TAXPAYERS WILL CLEAN UP THE RADIOACTIVE MESS.

SO IT GOES WITH CLEAN NUCLEAR ENERGY....ALMOST TOO CHEAP TO METER (NOT).

ps...IF MEMORY SERVES ME CORRECTLY, WASN'T THE COOK PLANT ONE OF THE
ONES IN THE UNITED STATES THAT HAD AN EMERGENCY CORE COOLING SYSTEM
THAT DIDN'T COMPLY WITH FEDERAL RULES?


Indiana Michigan Power Company, Docket Nos. 50-315 and 50-316, Donald
C. Cook Nuclear Plant, Units 1 and 2, Berrien County, Michigan

     Date of application for amendments: June 12, 2000, as supplemented
by letters dated November 7, 2000, June 19 and August 17, 2001.
     Brief description of amendments: The amendments would use the
methodology and the alternative source term (AST) in 10 CFR 50.67 and
described in NUREG-1465, ``Accident Source Terms for Light-Water
Nuclear Power Plants,'' and Regulatory Guide 1081, ``Alternative
Radiological Source Terms for Evaluating the Radiological Consequences
of Design-Basis Accidents at Boiling and Pressurized Water Reactors.''
Implementing the AST of 10 CFR 50.67 results in a new acceptance
criterion for 10 CFR Part 50, Appendix A, General Design Criterion 19,
of 5 rem total effective dose equivalent. The licensee determined that
use of the revised analysis assumptions, methodology, and acceptance
criterion required prior Nuclear Regulatory Commission (NRC) approval.
In addition, the NRC requires in 10 CFR 50.67, a license amendment to
implement the AST as a replacement for the Technical Information
Document 14844 source term.
     Date of issuance: November 13, 2001.
     Effective date: As of the date of issuance and shall be implemented
within 60 days.
     Amendment Nos.: 258 and 241.
     Facility Operating License Nos. DPR-58 and DPR-74: Amendments
approve changes to the updated final safety analysis report.
     Date of initial notice in Federal Register: August 23, 2000 (65 FR
51356).
     The supplemental letters contained clarifying information and did
not change the initial no significant hazards consideration
determination and did not expand the scope of the original Federal
Register notice.
     The Commission's related evaluation of the amendments is contained
in a Safety Evaluation dated November 13, 2001.
     No significant hazards consideration comments received: No.
