Title	Technical Specification Violation - Unsecured Reactor Left Unattended
Event Description	The following is a synopsis of a notification received from Reed College: The licensee made an official notification of a violation of technical specification (TS) 6.1.3 a 1 as well as TS 1, which defines the reactor as operating when it is not shutdown or secured. The Reactor Operator (RO) left the control room for approximately 30 seconds while the reactor was subcritical but not secured. Per the TS definition, the reactor is not secured if the reactor console key is in the console. The RO immediately returned to the control room and removed the key and ensured the reactor scrammed. The Senior Reactor Operator (SRO) was in the next room and was informed. Another SRO was in the control room but was not requalified.
