EXPLOSIVE GAS MIXTURE.(Hydrogen rich systems not designed to withstand a hydrogen explosion)
LIMITING CONDITION FOR OPERATION 3.11.2.5 The concentration of oxygen.in the waste gas system shall be limited to less than or equal to 2% by volume whenever the hydrogen concentration exceeds 4% by volume.
APPLICABILITY: At all times.
ACTION:
- a. With the concentration of oxygen in the waste gas system
^
greater than 2% by volume but less than or equal to 4%
by volume, reduce the oxygen concentration to the above limits, within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />,
- b. With the concentration of oxygen in the waste gas system greater than 4% by volume and the hydrogen concentration greater than g // g by volume, immediately suspend all additions of waste gases to
^
.the system and reduce the concentration of oxygen to less than or equal to 2% by volume without delay.
- c. The provisions of Specifications 3.0.3 and 3.0.4 are not applicable.
k-SURVEILLANCE REQUIREMENTS 4.11.2.5 The concentrations of oxygen in the waste gas system shall be determined to be within the above limits by monitoring the waste gases in the waste gas system as required by Table 3.3-16 of Specification 3.3.3.10.
