G2.1.1 (3.8)
In accordance with OP-AA-104-101, Communications, which ONE of the following evolutions would require a plant announcement?
A. Swapping a 28 VDC battery charger to the standby charger.
B. Commencing a fill of the Main Generator bulk hydrogen bottles from a vendor supply truck.
C. Commencing a Containment Pressure Relief to lower Containment pressure.
D. Performing radiography in the Turbine Building.
▶ Show Answer & Explanation
✓ D. Correct. IAW OP-AA-104-101, Communications, step 4.1.3.6, states in part the following; make public address announcements prior to activities that could change plant radiation levels. In this case, radiography performed in the Turbine Building will change radiation levels in the area and can expose personnel in the area to high radiation fields. Radiography performed in the Turbine Building are typically performed during refueling outages.
✗ A. Plausible because the operator may believe that this evolution meets the requirement for energizing of major electrical switchgear and buses. Swapping 28 VDC battery chargers does not meet the requirements of OP-AA-104-101 for page announcements.
✗ B. Plausible because the operator may believe that this evolution meets the requirements for alerting plant personnel of an unexpected event or condition. The candidate may believe that since Chemical off-loading at the polisher is announced, that off-loading Hydrogen would also be announced. Filling bulk hydrogen bottles does not meet the requirements of OP-AA-104-101 for page announcements.
✗ C. Plausible because the operator may believe that this evolution meets the requirements for alerting plant personnel of an unexpected event or condition or possibly changing radiation levels in the plant. Containment pressure relief does not meet the requirements of OP-AA-104-101 for page announcements.
