Enclosure Special Report 1-SR-2016-001-00 Fuel Building Ventilation System High Range Radioactive Gaseous Effluent Monitor Nonfunctional

Palo Verde Nuclear Generating Station Special Report 1-SR-2016-001-00 Fuel Building Ventilation System High Range Radioactive Gaseous Effluent Monitor Nonfunctional Docket No. STN 50-528, Unit 1 Reporting Requirement:

The Palo Verde Nuclear Generating Station Offsite Dose Calculation Manual revision 27 (ODCM) includes functionality requirements for radioactive gaseous effluent monitoring instrumentation. Action 42 of Table 2-1, specifies the following: when the number of FUNCTIONAL High Range Monitors is less than required by the Minimum Channels FUNCTIONAL requirement, the station will initiate the Preplanned Alternate Sampling Program to monitor the appropriate parameter(s) within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />, and:

a) Either restore the nonfunctional channel(s) to FUNCTIONAL status within 7 days of the event, or b) Prepare and submit a Special Report to the Commission within 14 days following the event outlining the action(s) taken, the cause of the nonfunctionality, and the plans and schedule for restoring the system to FUNCTIONAL status.

Initial Conditions:

At 0235 Mountain Standard Time (MST) on April 15, 2016, Unit 1 was in a refueling outage. The fuel building ventilation system high range radioactive gaseous effluent monitor (RU-146) was declared nonfunctional due to its 120 VAC Class 1E power supply being removed from service in support of a unit modification.

RU-146 was not restored to FUNCTIONAL status within 7 days.

Actions Taken:

The Preplanned Alternate Sampling Program was initiated to monitor appropriate parameters pursuant to ODCM Requirement ACTION 42 of Table 2-1 on April 17, 2016, at 1425 MST. On April 23, 2016, at 1543 MST, RU-146 was declared FUNCTIONAL after restoration of power and completion of the channel check surveillance test.

Cause of the Nonfunctionality:

There was no equipment malfunction associated with the nonfunctionality of RU-146.

The cause for exceeding the 7 days allowed by ODCM Action 42 of Table 2-1 was due to the schedule being extended to address issues with the unit modification designed to improve the reliability of 120 VAC inverters. The cumulative effect of the maintenance performed was RU-146 being out of service for greater than 7 days.

Palo Verde Nuclear Generating Station Special Report 1-SR-2016-001-00 Plans and Schedule for Restoring the System to FUNCTIONAL Status:

On April 23, 2016, at 1543 MST, RU-146 was declared FUNCTIONAL following completion of the modification work and after completion of the channel check surveillance test.
