g. With untreated gaseous effluents exceeding the limits of 3.9.2.e pursuant to Specification 3.9.2.e.3, submit a report which includes the following information:

(1) Identification of the inoperable equipment or subsystems and the reason for inoperability, (2) Action(s) taken to restore the inoperable equipment to OPERABLE status, and (3) Summary description of action(s) taken to prevent a recurrence.

h. With the annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC from all uranium fuel cycle sources exceeding the limits of Technical Specification 3.9.2.h, submit a report that defines the corrective action to be taken to reduce subsequent releases to prevent recurrence of exceeding the limits of Specification 3.9.2.h and includes the schedule for achieving conformance with those limits. This report, as defined in 10 CFR Part 20.005c, shall include an analysis that estimates the radiation exposure (dose)'to a MEMBER OF THE PUBLIC from uranium fuel cycle sources, including all effluent pathways and direct radiation, for the calendar year that includes the release(s) covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or concentrations.

If the estimated dose(s) exceeds the limits of Specification 3.9.2.h and if the release condition resulting in violation of 00 CFR Part 190 has not already been corrected, the report shall include a request for a variance in accordance with the provisions of 00 CFR Part 190. Submittal of the report is considered a timely request, and a variance is granted until staff action on the request is complete.

result of plant effluents pursuant to Specification 0.12.1.b, submit a report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions to be taken to reduce radioactive effluents so that the potential dose to a MEMBER OF THE PUBLIC is less than the limits of Specifications 3.9.1.b, 3.9.2.b and 3.9.2.c.

j. If the Limits of Technical Specifications 3.20 are exceeded, submit a report describing the cause of the unavailability, action taken and a schedule for restoration within 30 days.

83.20 BASES FOR LIMITINGCONDITIONS FOR OPERATION STANDBY FEEDVATER SYSTEM The purpose of this specification and the supporting surveillance requirements is to provide for administrative controls which will assure availability and performance of the non-safety grade standby feedwater system. The term availability is used rather than operability so as to positively avoid any implication or connotation that the standby feedwater 'system is designed or documented to meet safety system requirements such as seismic loads, environmental qualification, safety grade emergency power supply, etc. The system does consist of commercial grade components designed and constructed to industry and FPL standards for this class of equipment located in the outdoor plant environment typical of FPL facilities system wide. The system is expected to perform with high reliability, i.e., comparable to that typically achieved with this class of equipment. FPL intends to maintain the system in good operating condition with regard to appearance, structures, supports, component maintenance, calibrations, etc., but would not document these activities to the degree required for safety grade systems.

The standby feedwater system can be used as a backup to the auxiliary feedwater (AFW) system in the event the AFW system does not function properly. The system would be manually started and controlled by the operator when needed. In the event of a loss of offsite power the pumps can be powered via the non-safety grade diesel

'enerators connected to the non-vital 0160 volt bus.

A supply of 60,000 gallons from the Demineralized Water Storage Tank for the Standby Feedwater Pumps is sufficient water to remove decay heat from the reactor for six (6) hours for a single unit or two '(2) hours for two units. This was the basis used for requiring 60,000 gallons of water in the non-safety grade Demineralized iVater Storage Tank and is judged to provide sufficient time for restoring the AFW System or establishing make-up to the Demineralized iVater Storage Tank.

The motor driven standby feedwater pumos are not designed to NRC requirements applicable to emergency feedwater systems and not required to meet design basis events. These pumps may be out of service for up to 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> before initiating formal notification because of the extremely low probability of such an event.

The guidelines for NRC notification in case of both pumps being out of service for longer than 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> are provided in applicable plant procedures, as a VOLUNTARY 0 hour0 days <br />0 hours <br />0 weeks <br />0 months <br /> notiQcation.

B3.20-1 Amendment Nos. and

BASES FOR SURVEILLANCE RE UIRE MENTS STANDBY'EEDVATERSYSTEM Adequate demineralized water- for the standby feedwater system will be verified once per 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br />. The demineralized Water Storage Tank provides a source of water to several systems and therefore, requires daily verification.

The standby feedwater pumps will be verified available quarterly by starting and operating them in the recirculation mode typically from their normal power supply.

Also, during each unit's refueling outage, the respective standby feedwater pump will be powered from the unit's C bus utilizing Units I and 2 non-safety grade diesel generators and flow tested to the nuclear unit's steam generators. Prior to this test, the refueling unit's C bus will be de-energized and the necessary loads will be transferred to the other unit's C bus.

This surveillance regimen will thus demonstate availability of the entire flow path, backup non-safety grade power supply and pump associated with a unit at least outage. The pump, motor driver, and normal power supply availability would each'efueling typically be demonstrated by operation of the pumps in the recirculation mode at least quarterly.
