3.19* IODINE REMOVAL SYSTEM Specification:
3.19 The Iodine Removal System shall be OPERABLE with:
- a.
The Sodium Hydroxide Tank (T-103) containing a minimum 4,200 +/- 300 gallons of 30.0 +/- 0.5 percent by weight sodium hydroxide solution.
- b.
T-103 capable of supplying sodium hydroxide solution to the containment spray pump suction headers.
Applicability Specification 3.19 is applicable during POWER OPERATION.
Action With the Iodine Removal System inoperable:
- a.
Restore the system to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, or
- b.
Be in HOT SHUTDOWN within the next 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
The Iodine Removal System acts in conjunction with the containment spray system to reduce the post-accident level of fission products in the containment atmosphere.
Sodium Hydroxide is added to the recirculated water after a LOCA to establish a neutral pH.

Iodine Removal System The Iodine Removal System shall be demonstrated operable:
- a.
At least once per 31 days by verifying that each valve (manual, power operated or automatic) in the flow path that is not locked, sealed or otherwise secured in position, is in its correct position.
- b.
At least once per 6 months by:
- 1.
Verifying the volume of sodium hydroxide in tank T-103.
- 2.
Verifying the concentration of sodium hydroxide in T-103.
- 13.
Containment Purge and Ventilation Isolation Valves The Containment Purge and Ventilation Isolation Valves shall be determined closed:
- a.
At least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> by checking the valve position indicator in the control room
- b.
At least once every 6 months by performing a leak rate test between the valves.
