AGREEMENT STATE REPORT - LEVEL GAUGE SHUTTER FUNCTIONAL PROBLEMS

The following was received from the Louisiana Department of Environmental Quality via email:

"On 06/13/2019, Honeywell (HW) reported that they detected [on 6/12/19] malfunctions/operational difficulties of shutters on [three level density] gauges installed on processes during the annual inspection and operational checks/tests. The gauge shutters would not function as designed by the manufacturer due to the operational environment and need of routine maintenance. HW called a service contractor, RONAN Engineering, to evaluate these situations and determine the best courses of action to correct the problems.

"The sources and devices will remain installed on the processes until any repairs and maintenance are completed. This is not a radiation exposure hazard and does not pose a health and safety situation for the HW employees or the general public.

"The level gauges are RONAN Engineering S/N M7549, 50 mCi Cs-137, S/N HH113 50 mCi Cs-137 and M7666 100 mCi Cs-137 sources.

"This event is being reported to the NRC OP CENTER as required by Regulatory Requirement 10 CFR Part 30.50(b)(2) & LAC 33:XV 340.B."

AGREEMENT STATE REPORT - DAMAGED GAUGE

The following report was received from the state of Georgia via email:

"[On 6/17/2019,] the mill instrumentation group was called to check on a problem with readout from a nuclear gauge indication of high level for the number 26 chip digester. In the course of troubleshooting the problem, the Instrument Mechanic found that the gauge shutter handle would not remain locked in the [full] open position, but would slowly close as the digester operation caused the instrument to vibrate.

"The gauge shutter was left in the open position with instructions for operations to notify the Instrument Mechanic if needed. As the shutter for the digester level gauges are open during normal operations, this poses no added safety risk.

"Berthold was called and arrangements have been made for them to come on site on 6/27/2019 to either repair or replace the shutter."

The gauge is a Berthold model LB7442 with a 50 mCi Co-60 source (serial number 526-03-09).

AGREEMENT STATE REPORT - SHUTTERS STUCK OPEN ON THREE FIXED GAUGES

The following report was received from the Texas Department of State Health Services via email:

"A licensee consultant reported, with authorization from the licensee RSO, that three fixed gauges; two Vega model SHF1 devices, serial no.'s 5873CN and 5801CN, containing 20 mCi Cs-137 and one Ronan SA1, SN 9500gg, containing 1000 mCi Cs-137 were found to have stuck shutters during routine inspection. The shutters are in the open position, which is their normal operating mode. The gauges remain in positon on tanks
containing alkaline media and are still operating. A service company is being contacted to conduct repair/replacement. None are scheduled at this time. The gauges represent no hazard to the public due to their position."

LOSS OF POWER RESULTED IN A VALID ISOLATION SIGNAL

"At 0937 EDT on 6/27/19, Susquehanna Unit 2 had a control power fuse fail that caused a loss of power to one of two power distribution systems of the Reactor Protection System. This loss of power resulted in a valid isolation signal and actuation of the Primary Containment Isolation System that affected multiple systems, and is reportable per 10 CFR 50.72(b)(3)(iv)(A)."

The situation has been resolved and the plant is currently using an alternate power source. Offsite power and the Emergency Diesel Generators are still available.

The licensee notified the NRC Resident Inspector.
