The OPERABILITY of the Fire Suppression Systems ensures that adequate fire '
suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety-related equipment is located. The Fire Suppiession System consists of the water system, spray, and/or sprinklers, CO2, and fire hose stations. The collective capability of the Fire Suppression Systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility Fire Protect 5 9 Program.
The proper positioning of RF. valves is critical to delivering fire suppression CO2 at the fire source as quickly as possible. The option of increasing or decreasing the O frequency of valve position verification allows the ability to optimize plant operational resources. Should an adverse trend develop w;th CO2 Systems valve positions, the frequency of verification sha!I be increased. Similarly if the CO2 Systems valve position trends are positive, the frequency of verification could be decreased.
Through programmed trending of CO2 Systems as found valve positions, the CO2 fire protection systems will be maintained at predetermined reliability standards.
The RF/RY System Engineer is responsible for trending and determining verification frequencies based on the following:
Initially the frequency will be monthly.
Annually review ti.e results of the completed valve position verification procedures.
. if the results demonstrates that the valves are found in the correct position at least 99% of the time, the frequency of conducting :he valve position verification may be decreased from - monthly to quarterly or - quarterly to semiannually or -
semiannually to annually - as applicable. The frequency shall not be extended beyond annually (plus grace period).
i e- if the results demonstrates that the valves are not found in the correct position at least 99% of the time, the frequency of conducting the valve position verification shall be increased from - annually to serniannually or - semiannually to quarterly CHAPTER 16.9-3 Page 3 of 4 03/11/99
BASES: (cont'd) or'- quarterly to monthly - as applicable. The valve position verification need not be conducted more often than monthly.
In the event that portions of the Fire Suppression Systems are inoperable, altemate backup fire-fighting equipment is required to be made available in the affected areas until the inoperable equipment is restored to service. When the inoperable fire- !
fighting equipment is intended for use as a backup means of fire suppression, a l longer period of time is allowed to provide an attemate means of fire fighting than if the inoperable equipment is the primary means of fire suppression.

An acceptable method to satisfy the Functional Test requirement for smoke detectors is by pre-testing (actuates at the required setpoint within the required accuracy) the detection instruments, replacing all detection instruments on a signaling circuit, and then actuating one detection instrument on the signaling circuit to verify operability of alarm.
EFA Zone 65 consists of 18 smoke detectors. Table 16.9-3 lists the Minimum Instruments Operable for EFA Zone 65 as 15. The basis for this difference is as follows:
. Two smoke detectors are located in the Auxiliary Service Building. These smoke detectors are not included in the Tab a 16.9-3 EFA Zone 65 Minimum Instruments Operable because they are located in a nonsafety-related area.
. The smoke detector located in the Spent Resin Batching Tank Room is not included in the Table 16.9-3 EFA Zone 65 Minimum Instruments Operable because the Spent Resir. Batching Tank Room is a High Rad Area with minimal combustible loading. Entering this room twice a year to perform smoke detector testing is not justified. The Spent Resin Batching Tank Room is enclosed by four foot thick reinforced concrete walls. The only access to this room is through a O reinforced concrete hatch in the 594+0 Elevation floor slab. In the unlikely event that a significant fire should occur in the Spent Resin Batching Tank Room, the smoke detectors adjacent to (Elevation 577 - EFA Zone 65) or above (Elevation 594 - EFA Zone 34) the Spent Resin Batching Tank Room would provide an alarm to the Control Room. The areas adjacent to the Spent Resin Br&hing Room rely on the same assured train of Post Fire Safe Shutdown; therefore, a fire in this room would have no adverse impact on Post Fire Safe Shutdown even in the unlikely event of fire extension into the adjacent areas.
EFA Zones 58 and 67: Each consist of 21 smoke detectors. Table 16.9-3 lists the Minimum Instruments Operable for EFA Zones 58 and 67 as 19. The basis for this difference is as follows:
. The smoke detectors located in the Unit 1 (Zone 58, rooms 476 and 477) and l a Unit 2 (Zone 67, rooms 467 and 468) Letdown Heat Exchanger and Moderating l Heat Exchanger Rooms are not included in the Table 16.9-3 Minimum .
Instruments Operable because these rooms are High Rad Areas with minimal combustible loading. Entering these rooms twice a year to perform smoke detectcr testing is not justified. These rooms primarily consist of piping and a heat exchanger which are not significantly prone to fire damage. The Moderating' Heat Exchanger Rooms are in a safety related ares, but contain O

U components which do not perform a safety related function nor a safe shutdown l function. The Letdown Heat Exchanger Rooms contain safety related components, however, they de not perform a safe shutdown function. These rooms are enclosed by two to three foot thick concrete walls with ca common labyrinth entrance. The outer, common entrance has a wire mesh door. In the unlikely event that a significant fire should occur in one of these heat exchanger rooms, the smoke detectors adjacent to these rooms would provide an alarm to the Control Room. The areas adjacent to these rooms rely on the same assured train of Post Fire Safe Shutdown; therefore, a fire in either of these rooms would have no adverse impact on Post Fire Safe Shutdown even in the unlikely event of fire extension into the adjacent areas.
I EFA Zones 55 and 64: Each consist of 9 smoke detectors. Table 16.9-3 lists the Minimum Instruments Operable for EFA Zones 55 and 64 as 8. The basis for this difference is as follows:
. The smoke detectors located in the Unit 1 (Zone 55, room 417) and Unit 2 (Zone 64, room 408) Fuel Pool Cooling (KF) Demineralizer Rooms are not included in ,
the Table 16.9-3 Minimum Instruments Operable because the KF Demineralizer l Rooms are High Rad Areas with minimal combustible loading. Entering these rooms twice a year to perform smoke detector testing is not justified. These rooms primarily consist of piping and a demineralizer which are not significantly b prone to fire damage. These rooms are in a safety related area, but contain components which do not perform a safet'/ related function nor a safe shutdown j function. These rooms are enclosed by two and three foot thick concrete walls I with a labyrinth entrance. The entrance has two doors. The outer door has a wire mesh above it and the inner door has an open grill. In the unlikely event j that a significant fire should occur in one of the KF Demineralizer Rooms, the j smoka detectors adjacent to these rooms would provide an alarm to the Control j Room. The areas adjacent to the KF Demineralizer Rooms rely on the same >
assured train of Post Fire Safe Shutdown; therefore, a fire in either of these rooms would have no adverse impact on Post Fire Safe Shutdown even in the unlikely event of fire extension into the adjacent areas.

i COMMITMENT (con't)
- deviations from the sampling schedule of Table 16.11-7; and discussion of all !
analyses in which the LLD required by Table 16.11-8 was not achievable.
I 16.11-16.2 RADIOACTIVE EFFLUENT RELEASE REPORT (See Note)
The Radioactive Effluent Release Report covering the operation of the unit during the previous calendar year shall be submitted before May 1 of each year. The Radioactive Effluent Release Reports shallinclude a summary of the quantities of I radioactive liquid and gaseous effluents and solid waste released from the unit. i l
The Radioactive Effluent Release Report shall include an annual summary of hourly meteorological data collected over the previous year. This annual summary may be
)
either in the form of an hour-by-hour listing on magnetic tape of wind speed, wind direction, atmospheric stability, and precipitation (if measured), or in the form of joint frequency distributions of wind speed, wind direction, and atmocpheric stability. (in lieu of submission with the Radioactive Effluent Release Report, the licensee has the option of retaining this summary of required meteorological data on site in a file !
that shall be provided to the NRC upon request.) This same report shall include an assessment of the radiation doses due to the radioactive liquid and gaseous effluents released from the unit or station during the previous calendar year. This
. same report shall also include an assessment of the radiation doses from radioactive liquid and gaseous effluents to MEMBER OF THE PUBLIC due to their ;
activities inside the SITE BOUNDARY during the report period. All assumptions !
used in making these assessments, i.e., specific activity, exposure time and location, shall be included in these reports. A five-year average of representative onsite meteorological data shall be used in the gaseous effluent dose pathway calculations. Dispersion factors (x/Qs) and deposition factors (D/Qs) shall be generated using the computer code XOODOQ (NUREG/CR-2919) which implements NRC Regulatory Guide 1.111. The meteorological conditions concurrent with the time of release shall be reviewed annually to determine if the five-year average values should be revised. The assessment of radiation doses !
shall be perfonned in accordance with the methodology and parameters in the .
OFFSITE DOSE CALCULATION MANUAL (ODCM). l The Radioactive Effluent Reiease Report shall also include an assessment of radiation doses to the likely most exposed MEMBER OF THE PUBLIC from reactor i releases and other nearby uranium fuel cycle sources, including doses from primary l effluent pathways and direct radiation, for the previous ca!endar year to show conformance with 40 CFR Part 190, " Environmental Radiation Protection Standards !
for Nuclear Power Operation". Acceptable methods for calculating the dose l contribution from liquid and gaseous effluents are given in Regulatory Guide 1.109, ;
Rev.1, October 1977. !
