| event text = On 12/30/17 at 0717 CST, the University of Missouri-Columbia Research Reactor (MURR) was shut down due to the loss of negative pressure in the reactor containment building. Prior to the shutdown, the reactor was operating for a period of time during the loss of negative pressure which is a deviation from MURR Technical Specifications (TS). This email is a required notification per 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 TS Limiting Conditions for Operations (LCOs). MURR was not in compliance with TS's 3.4.b and 3.4.a.(6). | | event text = On 12/30/17 at 0717 CST, the University of Missouri-Columbia Research Reactor (MURR) was shut down due to the loss of negative pressure in the reactor containment building.
