The University of Missouri Research Reactor Center has an impeccable 40+ year record of safe operation. This safety record is a combination of stringent NRC-directed safety regulations, high-quality technical and operations staff, and a philosophy of proactive, preventive maintenance. MURR operates 6.5 days per week; 52 weeks per year.

MURR's reliability record is the envy of the industry.

Missourians are no strangers to nuclear energy, relying heavily on Ameren UE's nearby Callaway plant to cool or heat their businesses and homes and feed their equipment and appliances. But MURR, as a multifunctional research reactor, differs significantly from such a power reactor. As the table below shows, MURR is considerably smaller. While a power reactor such as Callaway needs a source of electricity to cool the reactor core, MURR's pool is capable of absorbing all the heat from the reactor core without the aid of forced convection.
