"In 2010, Control Room Envelope testing was conducted to satisfy SR 3.7.10.5 (this surveillance testing is required each 6 years). At that time, as a prerequisite, the surveillance procedure contained a step to add water to two floor drain loop seals that penetrated the Control Room Envelope; this practice was determined to be unacceptable preconditioning. Because the 2010 surveillance test was the first performance of this surveillance, the unacceptable preconditioning resulted in the following: a never-performed surveillance, failure to meet the associated surveillance requirement, and an inoperable Control Room Envelope. At 2028 CDT the station entered LCO 3.7.10, Condition B.
"The station has taken action to periodically add water to the loop seals; this practice validates the loop seals will remain full of water. This action ensures, through Engineering judgment, that the loop seals will perform their function and the Control Room Envelope will provide adequate protection to the plant operators.
"The NRC Resident Inspector was notified."
The floor drains are located inside the control room envelope near the control room chillers. Prior to this report, filling the loop seal was performed sporadically. The loop seal is now filled daily.

"On 9/10/13, the Tracer Gas Test of Control Room failed to meet its acceptance criteria for the surveillance test. The failure was due to three (3) doors with minor seal leaks and/or test uncertainty. The station is evaluating door repairs and test uncertainty.
"The actions for the test failure to offset the consequences of the inoperable Control Room Envelope have been modified to protect the operators with the use of SCBA's and Potassium Iodine (KI) in the event of a DBA.
"The NRC Resident Inspector was notified."
The R3DO (Lipa) was notified. |

PART 21 GROUP (E-MA)
| Event Text PART 21 REPORT - IMPROPER DEDICATION OF ACTUATOR PARTS
Fisher issued an information notice (FIN 2013-03) to alert Palo Verde Nuclear Generating Station of an issue associated with two valve assemblies supplied to PVNGS by Fisher. Fisher determined that the valves were provided with actuator parts that were not properly processed per active valve requirements specified in the purchase order. Specifically, Fisher provided commercial grade parts instead of commercial grade dedicated items.
Arrangements have been made with PVNGS to retrofit the correctly processed parts on the subject valves. | |
