AGREEMENT STATE REPORT - TWO NUCLEAR GAUGES FOUND WITH SHUTTERS STUCK OPEN
The following report was received from the Texas Department of State Health Services via email:
"On January 25, 2018, the Agency [Texas Department of State Health Services] was notified that two of the licensee's Ohmart-Vega Model SHLG fixed nuclear gauges were found to have shutters stuck in the open position during preventative maintenance. These gauges normally operate with the shutter in the open position. There is no increased risk of exposure to any member of the public or licensee employees. Coordination is underway between the licensee, the service company, and the manufacturer for the gauges to be removed and returned to the manufacturer for repair or disposal.

SN: 3253CM 2,000 milliCuries cesium-137
SN: 4021CM 2,000 milliCuries cesium-137"

POTENTIAL DEFICIENCY ASSOCIATED WITH AN ITEM RELIED UPON FOR SAFETY
"During a self initiated review, ISA [Integrated Safety Analysis] Staff performed a preliminary review of the ISA to determine whether or not there was a chemical safety issue concerning the proximity of combustible fuel to the yard tractors/shuttle lifts that UUSA's [Urenco USA] Logistics organization uses to move UF6 [Uranium Hexa Fluoride] cylinders around outside on site.
"ISA staff determined that the ISA lacked sufficient information regarding the proximity of combustible fuel to the IROFS36c [Item Relied Upon for Safety] controlled yard tractors/shuttle lifts. ISA determined that revisions to one, or more, of the applicable IROFS Boundary Definition Documents was necessary to establish operator actions to ensure that the volumetric fuel limit is not compromised due to the proximity of other fuel sources, therefore UUSA is conservatively making this report.
"UUSA remains in a safe and stable condition. UUSA Logistics has issued a stop work that prohibits applicable cylinders from traveling where proximity to combustible fuel could occur.
"10 CFR 70.50(c)(iii)
(A) There was not a material release, no radiological or chemical hazards were present.
(B) No exposure occurred
(C) A deficiency exists in the ISA in which the limiting of external fuel sources near IROFS36c controlled yard tractors/shuttle lifts was not discussed
(D) IROFS36c remains operable and available to perform its safety function. The identified deficiency only affects applicable UF6 cylinders that could be moved in proximity to other fuel sources. UUSA has issued a stop work to adequately address the deficiency.
(iv) No external conditions affect this event
(v) A stop work was issued to prevent the movement of applicable UF6 cylinders where proximity to other fuel sources could occur
(vi) An event did not occur at UUSA. UUSA remains in a safe and stable condition
(vii) No emergencies have been, nor will any be declared
(viii) No state or other federal agencies will be notified
(ix) No press releases are planned."
The licensee will be contacting the NRC Region 2 office (Ortiz).

OFFSITE NOTIFICATION DUE TO SCREEN WASH PUMP MOTOR FIRE
"At 1901 PST on January 25, 2018, the Control Room received a fire alarm, followed by screen wash and 480v load center alarms a few minutes later. The intake operator and on-site fire department personnel were promptly dispatched to the scene and confirmed within 15 minutes there was no active fire. As a conservative measure, off-site fire assistance was initially requested, however [this request] was canceled a short time later. While on-site fire personnel were locally assessing the damage to screen wash pump 1-2, a brief flare-up occurred at the pump motor which was immediately extinguished. Units 1 and 2 remained stable and two screen wash pumps remain available. There is no risk to plant safety or personnel and both units continue to operate at power. Current efforts are focused on determining the cause of the situation."
The licensee notified the NRC Resident Inspector and CAL FIRE. The licensee issued a media/press release.

EN Revision Text: AGREEMENT STATE REPORT - STUCK SHUTTER
The following was received from the New Hampshire Radiological Health Section via email:
"[In January 2018], during routine semi-annual leak testing of a generally licensed fill-level gauge, it was discovered that the gauge shutter would not close completely by ordinary means and the red 'Source ON' status indicator lamp remained continuously lit. A manual shutter handle within the actuation assembly was used to close the shutter. While doing so, a green wire was noted as brushing against the shutter linkage and impeding its operation. The gauge was already out of service for maintenance, and remained so until the shutter mechanism was repaired. No personnel exposure.
"The cause was determined by the service technician as a wire interfering with the path of the shutter linkage, preventing full closer of the shutter. The wire was moved out of the way, allowing the shutter to move along its full path as designed."
Gauge Details: Americium-241, 300mCi (11.1 GBq) sealed source; Industrial Dynamics Model 19567; s/n 156LX; no detectable leakage
The New Hampshire Radiological Health Section considers this event closed.
Report ID #: #NH18-0001
