  • d WASTE GAS DECAY TANKS 2.17 The quantity of radioactivity contained in each Waste Gas Decay Tank shall be limited to less than or equal to 39000 curies (considered as Xe 133).

APPLICABILITY: At all times.

ACTION:

a. With the quantity of radioactivity in any Waste Gas Decay Tank exceeding the above limit, immediately suspend all additions of radioactive material to that tank, and w' thin 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> reduce the tank contents to within its limit.

SURVETilANCE REQUIREMENTS 2.17.1 The quantity of radioactive material contained in each Waste Gas l Decay Tank shall be determined

  • to be within the limit at least once-per 7 days whenever radioactiva materials are being added to the tank, and at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> during primary coolant system DECASSING operations.

Determining that each waste gas decay tank is in compliance with the limit may be done by a method other than direct sampling of the tank provided it is in accordance with an approved procedure.
