----------- [ Current event for IL_QuadCities_1 ]

20190205 | IL_QuadCities_1 | UNIT ONE HPCI SYSTEM INOPERABLE DUE TO BLOWN FUSE |
https://www.nrc.gov/reading-rm/doc-colle...ml#en53861

"On February 5, 2019, at 1804 [CST], during a Unit 1 High Pressure Coolant Injection (HPCI) operability surveillance,
a fuse blew in the logic for the motor speed changer for the turbine.

The Unit 1 HPCI system was taken out of service for planned maintenance earlier in the day.

The fuse issue was not related to any maintenance activities.
[
It's just a coincidence that they were testing when the " fuse blew in the logic "
this sounds like a fuse on a cicuit card or something, not a main panel fuse.
There have been other ENs detailing how tech's have caused problems while installing jumper wires that cause unintended
connections ( short circuits ) which can activate/deactivate systems.
Jumper wires are commonly used to defeat/enable signals during testing.

There have also been PART21 EN's concerning faulty components that can cause fuses to blow.  
]


Had HPCI been demanded, this fuse failure would not have allowed HPCI to reach its required speed.
HPCI remains inoperable pending resolution of the issue.
The Reactor Core Isolation Cooling (RCIC) system was confirmed operable.
There were no other systems inoperable at the time of the event.

HPCI had been last successfully tested on November 6, 2018.
[ So this unit appears to have a regular HPCI test schedule of 30 days. ]

"This event is being reported as a condition that could have prevented fulfillment of a safety function in accordance with 10 CFR 50.72(b)(3)(v)(D).
The HPCI system is a single train system and the loss of HPCI could impact the plant's ability to mitigate the consequences of an accident.

"The NRC Senior Resident Inspector has been notified."

Inoperable HPCI places the unit in a 14 day Technical Specification Limiting Condition of Operability.
