AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

The following report was received via e-mail:

"At 0730 [CDT], July 17, 2016, an incident occurred at a temporary job site. The incident occurred when a water truck operating on the construction site came into contact with the moisture density gauge, causing damage to the source rod and casing. Licensee and Corporate RSO notified Mississippi Department of Health on July 18, 2016 about the incident.

"With Terracon having taken their gauge back to Little Rock, Arkansas, the Mississippi Department of Health sought out inspectors from Arkansas Department of Health to gather information from Terracon's local office.

"According to the inspectors sent by Arkansas Department of Health, the individual at the site of the incident had established a 15 foot radius around the gauge. The water truck and driver were requested to stay at the site until the Corporate Radiation Safety Officer was notified. Another employee was sent to the incident site with a TroxAlert meter. The radiation survey meter was current on calibration.

"The gauge involved in this incident is a Troxler Model 3440 Serial Number 25123 with an Am-241 [source], Serial Number: 47-21331 and Cs-137 [source], Serial Number: 75-7299. The readings were completed by Arkansas Department of Health with a Ludlum Model 3, SN 62645, and calibration date: 02/03/2016.

"Once readings were complete, the Corporate RSO allowed the water truck and driver to leave and to bring the gauge back to Little Rock, AR. The gauge was then put back together and stored in their secured storage location inside the Terracon building. Additional readings were taken on July 18, 2016 at approximately 0830."

Sources: Am-241 - 40 mCi: Cs-137 8 mCi

Incident Number: MS-16004

* * * UPDATE FROM BENJAMIN CULPEPPER TO STEVEN VITTO ON 09/13/2016 AT 1154 [EDT] * * *

The following report was received via e-mail:

"The gauge was examined by the Arkansas Department of Health on July 18, 2016, in Terracon's Little Rock office and a leak test was performed by both Terracon and Arkansas Department of Health. The resulting leak tests showed that the source was not damaged, and a copy of those leak tests were provided to the Mississippi State Department of Health.

"The gauge technician involved in the incident has been through additional training on gauge usage including transportation and security. Terracon's accountability process was initiated at their Arkansas location as well as the retraining.

"Terracon was issued violations for not properly contacting Mississippi State Department of Health and Arkansas Department of Health about the event. The Corporate RSO for Terracon responded to both violations issued from both State Health Departments. Their response was found to be adequate in correcting the items of noncompliance during this investigation.

"The Arkansas Department of Health sent Mississippi State Department of Health confirmation that Terracon has addressed the issued violations adequately on September 12, 2016."

AGREEMENT STATE REPORT - NUCLEAR GAUGE SHUTTER COULD NOT BE OPERATED

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

"On August 11, 2016, the Agency [Texas Department of State Health Services] was notified by the licensee that during a routine annual inspection, the shutter on an Ohmart Vega SH-F1 nuclear gauge could not be operated. The gauge contains a 15 millicurie (original activity) source. The shutter's operating handle no longer operates the shutter. It is in the open position which is the normal operating position for the shutter. A service company is on site and will try to repair the gauge. The gauge is mounted on the top of a tall vessel and does not present an exposure hazard to the licensee's workers or members of the general public. This event is similar to EN 52167. Additional information will be provided as it is received in accordance with SA-300."

Texas Incident #: I9425

* * * UPDATE FROM ART TUCKER TO STEVEN VITTO AT 1744 EDT on 09/13/16 * * *

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

"The licensee reported the activity of the source was 50 milliCuries and not 15 milliCuries as initially reported. Additional information will be provided as it is received in accordance with SA-300."

UNANALYZED CONDITION INVOLVING STATION SERVICE WATER TRAINS

"Based on a walk down in the Service Water Intake Structure (SWIS) with the NRC Resident [Inspector], it was observed that a vertical section of 4 inch Fire Protection pipe that provides a normally pressurized source of fire water supply to the overhead sprinkler system in the SWIS is not Moderate Energy Line Break (MELB) shielded similar to the horizontal segment of the same line near the ceiling. In the event of a MELB crack along any portion of the unshielded pipe, the MELB has a potential impact to the function of any one of the 4 Service Water pumps. Only one train at a time would be affected during the event. This is due to the physical characteristics of the postulated MELB and the configuration/separation relative to the source line and target pumps and/or associated Motor Control Centers (MCCs) that support pump operation.

"Since the Service Water trains have been periodically declared inoperable at various times in the last three years for surveillance testing or maintenance, if the MELB were to have occurred during these times and affected the opposite train, then two Service Water trains could have been inoperable and this represents an unanalyzed condition. At the time of discovery, all four Service Water trains were operable, therefore, this condition is not reportable as a loss of safety function per 10 CFR 50.72(b)(3)(vi).

"Currently, Service Water Train B on each Unit has been declared inoperable per Technical Specification (TS) 3.7.8. This condition will be corrected within the 72-hour Completion Time of TS 3.7.8.

"Currently, Emergency Diesel Generator B on each Unit has been declared inoperable per Technical Specification (TS) 3.8.1. This condition will be corrected within the 72-hour Completion Time of TS 3.8.1.

"The NRC Resident Inspector was informed."

STEAM PROPAGATION BARRIER DOOR FOUND OPEN

"During routine operator rounds at 2030 EDT, a steam propagation barrier door (SPBD) was discovered propped open for maintenance activities without appropriate station controls. This condition was in existence from approximately 1720 EDT to 2042 EDT when the SPBD was restored to its normal configuration. Throughout the approximate 3 hours and 22 minutes, when the SPBD was propped open, both trains of chill water were rendered non-functional due to a potential high energy line break. This subsequently rendered both trains of high-head safety injection inoperable, which placed the plant in Technical Specification 3.0.3. This condition was corrected prior to commencing a Technical Specification 3.0.3 plant shutdown. This condition is reportable under 10 CFR 50.72(b)(3)(v) as any event or condition that at the time of discovery could have prevented the fulfillment of a safety function.

"The NRC Senior Resident Inspector has been notified."
