<h3>Statement of Lessons Learned</h3>
<pre>On Thursday, November 2, 2023, an alarm, indicating that there was water leaking into the beam dump cooling building, was overlooked. This resulted in a delay in identifying the cause until Monday, November 6, 2023, and increased the clean-up efforts of a radiological contamination issue.</pre>
<h3>Discussion of Activities</h3>
<pre>On Thursday, November 2, 2023, the notification, indicating that there was water leaking into the beam dump cooling building, was overlooked by Facilities Management & Logistics (FML) Subject Matter Expert (SME).

On Friday, November 3, 2023, the FML SME noted that the beam dump cooling building alarm was still active around the same time others discovered water on the floor and condensation on the walls and ceilings near the door of the building. The building was immediately secured. The building's pump was leaking, so it was turned off. Air samples for tritium were taken. The results determined the air quality to be two orders of magnitude below the level where extra precautions were needed. 

On Saturday, November 4, 2023, due to continued multiple alarms indicating water was still coming from the pump area, the nitrogen pressure to the system was isolated. 

By Monday, November 6, 2023, the actual source of the leak was identified as a welded connection in the system piping at the post-filter housing. During the interval, the make-up system had turned on a total of four times and an estimated 170 gallons of contaminated water ultimately leaked into the building. 

On Thursday, November 9, 2023, the post-filter housing was bypassed. It was determined that a thorough check of the electrical system would need to be performed before running the system.

Between Tuesday, December 14, 2023, and Monday, December 20, 2023, the Radiation Control Department oversaw the cleanup of the water and the application of decontamination gel. When the main pump was restarted, additional water leaks were detected indicating additional leak points in the post-filter housing.</pre>
<h3>Analysis</h3>
<pre>FML is responsible for monitoring the beam dump cooling building alarms. The initial alarm, activated on Thursday, November 2, 2023, indicated a water leak in the building. This did not take priority as it was one of approximately 30 notifications that day. It was 12 hours before the alert was recognized as a high priority. The misidentification contributed to an increased volume of contaminated water allowed to leak from the system and expanded the scope of the cleanup effort. 

The failure of the weld in the Low Conductivity Water (LCW) system was unanticipated, even though the component had been in service for over 30-years, and a weld failure in a comparable system occurred two years prior.</pre>
<h3>Recommended Actions</h3>
<pre>Reaction plans are to be developed and implemented in order to address subsequent leak events in the LCW system.

An assessment of the use frequency and duration of the existing Tritium Monitoring and Disposal Units (TMDU), supporting the Beam Dump LCW systems, will be conducted to determine whether the operating parameters are in accordance with As Low as Reasonably Achievable (ALARA) principles. 

Cameras are to be installed in the interior of beam dump buildings to improve remote response, assessment and verification of interior conditions.

Notification procedures for the LCW System will be developed to address and clarify protocols by which critical monitoring system alarms are transmitted, to whom, and any required actions.

A viable supplier for pre-filter housing parts, considered operationally critical, vulnerable, or susceptible to failure, is to be contacted and an appropriate inventory of spare parts secured.

A Failure Modes and Effects Analysis will be conducted to identify and prioritize improvements in the design and management of the Beam Dump Cooling LCW system.</pre>
<h3>Applications</h3>
<pre>Stay vigilant when receiving notifications. Ask for help if the purpose is unclear.

Learn from others. Even if a situation is not exactly the same as yours, consider similarities and imitate good prevention practices.</pre>
