3.14 Control Room Emergency Air Cleanup System LIMITING C0KDITIONS FOR OPERATION 3.14.1 Two independent Control Room Emergency Air Cleanup Systems shall be operable with:
a.
An air handling unit for each system, b.
A condensing unit for each system.
c.
A HEPA/ charcoal filter unit and fan for each system.
d.
All dampers, duct work and interlocks which are required to operate during accident conditions.
APPLICABILITY: At all times.
ACTION:
For Plant conditions above cold shutdown condition:
With one Control Room Emergency Air Cleanup System inoperable, restore the inoperable system to an operable status within 7 days, or be in at least hot shutdown within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, and in cold shutdown within the following 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
For cold shutdown condition:
1 a.
With one Control Room Emergency Air Cleanup System inoperable, restore the inoperable system to an operable status within 7 days, or suspend all core alterations except for testing one rod at a time, and limit positive reactivity changes via boron dilution to evolutions which do not reduce the boron concentration to less than shutdown boron concentration, b.
With both Control Room Emergency Air Cleanup Systems inoperable, immediately suspend all core alternations except for testing one rod at a time, and limit positive reactivity changes via boron dilution to evolutions which do not reduce the boron concentration to less than shutdown boron concentration.
For refueling operations:
a.
With one Control Room Emergency Air Cleanup System inoperable, restore the inoperable system to an operable status within 7 days, or suspend all core alterations and limit positive reactivity changes via boron dilution to evolutions which do not reduce the boron concentration to less than refueling boron concentration.
b.
With both Control Room Emergency Air Cleanup Systems inoperable, immediately suspend all core alternations and limit positive reactivity changes via boron dilution to evolutions which do not reduce the boron concentration to less than refueling boron concentration.
