Byron Vent Stack Radiation Monitors 1RE-PR028 and 2RE-PR028 were declared inoperable at 0753 on 11/10/84 while Unit 1 was in MODE 6.

Gas grab samples are required to be taken, according to the Technical Specifications, every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> while the monitors are inop-erabla Samples were not taken for 1RE-PR028 at 2145 on 11/10/84, 0945 on 11/11/84, and 2145 on 11/12/84.

The samples were not taken for 2RE-PR028 at 0530 on 11/11/84, 1730 on 11/11/84, 0530 on 11/12/84, and 1730 on 11/12/84.

These radiation monitors were restored to service at 0533 on 11/13/84 so no grab samples were required after that time.

This does not affect public safety since there is no irradiated fuel on s'ite.

Instruction has been given to Operating and Rad-Chem personnel responsible for assuring that these samples are taken in the proper time interval.
