Decay Time B 3.9.9 B 3.9 REFUELING OPERATIONS B 3.9.9 Decay Time BASES BACKGROUND This postulated refueling accident involves the drop of a fuel assembly on top of the reactor core during refueling operations (Ref. 1). The drop over the reactor core is more limiting than the drop over the spent fuel pool since the kinetic energy for the drop over the reactor core area (greater than 23 feet) produces a larger number of damaged fuel pins on impact than the shorter drops that could occur over the fuel pool. The refueling accident is analyzed using Alternate Source Term methodology governed by 10 CFR 50.67 and the guidelines of Regulatory Guide 1.183 (Ref. 2).
The refueling accident analysis assumes that the accident occurs at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after plant shutdown. Specifically, a 24-hour radioactive decay time of the fission product inventory is assumed during the interval between shutdown and movement of assemblies in the reactor core.
APPLICABLE The minimum requirement of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of reactor subcriticality SAFETY ANALYSES prior to movement of irradiated fuel assemblies in the reactor vessel ensures that sufficient time has elapsed to allow the radioactive decay of the short-lived fission products. This decay time is an initial condition of the refueling accident analysis.
Decay time satisfies the requirements of Criterion 2 of the NRC Policy Statement (Ref. 3).
(continued)
BFN-UNIT 1 B 3.9-36 Amendment No. 251
Decay Time B 3.9.9 BASES (continued)
LCO The specified decay time limit requires the reactor to be subcritical for at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Implicit in this TS is the Applicability (during movement of irradiated fuel in the reactor vessel). This ensures that sufficient time has elapsed to allow the radioactive decay of the short-lived fission products, thus reducing the fission product inventory and reducing the effects of a refueling accident.
APPLICABILITY The decay time restriction is applicable only during movement of irradiated fuel in the reactor vessel following reactor operation. Therefore, it effectively prohibits movement of irradiated fuel in the reactor vessel during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> following reactor shutdown.
ACTIONS A.1 I With the reactor subcritical less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, all movement of irradiated fuel in the reactor vessel must be suspended. As stated above, movement of irradiated fuel in the reactor vessel is prohibited during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> following reactor shutdown.
SURVEILLANCE SR 3.9.9.1 REQUIREMENTS Since movement of irradiated fuel in the reactor vessel is prohibited during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> following reactor shutdown, a verification of time subcritical must be made prior to movement of irradiated fuel in the reactor vessel. This is done by confirming the time and date of subcriticality, and verifying that at least 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> have elapsed. The Frequency of "once prior to movement of irradiated fuel in the reactor vessel" ensures that the operation is within the design basis assumption for decay time in the refueling accident analysis.
