RESEARCH AND TEST REACTOR FORCED SHUTDOWN DUE TO FAILURE OF REGULATING BLADE DRIVE MECHANISM
"On 4/8/20 at 0100 CDT, the University of Missouri-Columbia Research Reactor (MURR) was shut down due to a failure of the regulating blade drive mechanism to move the regulating blade during reactor operation. This email is a required notification per MURR Technical Specification (TS) 6.6.c.(1) to report to the NRC Operations Center that an Abnormal Occurrence, as defined by MURR TS 1.1, had occurred. Specifically, MURR was not in compliance with all Limiting Conditions for Operations (LCOs). MURR was not in compliance with two (2) LCOs: 1. TS 3.2.a states, 'All control blades, including the regulating blade, shall be operable during reactor operation,' and 2. TS 3.2.f states, 'The reactor shall not be operated unless the following rod run-in functions are operable.' Specifically, the rod run-in function that occurs when the regulating blade position is less than or equal to 10 percent withdrawn was not operable as TS 3.2.f.8 requires.
"The regulating blade drive mechanism was repaired, post-maintenance operability testing was conducted on the regulating blade, and permission from the Reactor Facility Director was obtained prior to the reactor returning to operation later on 4/8/20. Currently, MURR is at 10 MW. A detailed event report will follow within 14 days as required by MURR TS 6.6.c.(3)."

LOSS OF TECHNICAL SUPPORT CENTER FUNCTIONALITY
"On April 8, 2020 at 0945 EDT, a condition impacting functionality of the Technical Support Center (TSC) Ventilation System was discovered. The issue involved a loss of TSC habitability due to failure of outside air intake fans. These fans were
returned to service at 1237 EDT and the TSC is currently functional.
"This is an eight-hour, non-emergency notification for a loss of Emergency Assessment Capability. This event is reportable in accordance with 10 CFR 50.72(b)(3)(xiii) because the condition affects the functionality of an emergency response facility.
"This condition does not affect the health and safety of the public or plant personnel. The NRC Resident Inspectors have
been notified."
