MIT reported to the NRC this morning that it had shut down its 6 megawatt reseach reactor early Sunday morning. The reactor shut itself down following a high radiation reading during startup. MIT initially thought that the signal was the result of “noise on the channel.” Technicians decided to restart the reactor. During the restart, operators noticed that one monitor failed to change as control rods were removed, although power readings showed that the reactor was increasing output. At that point, operators decided to manually shut down the reactor pending further testing.
