Reactor operator

A reactor operator (or nuclear reactor operator) is an individual at a nuclear power plant who is responsible for directly controlling a nuclear reactor from a control panel and is the only individual at a nuclear power plant who can directly alter significant amounts of reactor reactivity. The reactor operator occupies a position of great responsibility that may require him or her to start up a nuclear reactor, shut down a critical nuclear reactor, monitor reactor parameters, or respond to a casualty of the nuclear reactor.

All reactor operators are required to be licensed or qualified by their respective governing body (for example, the NRC for U.S. civilian nuclear reactors and Naval Reactors for U.S. naval reactors).

Civilian reactor operator licensing

There are two types of civilian reactor operators licensed by the NRC: reactor operators (RO) and senior reactor operators (SRO).[1][2]

Reactor operator

A reactor operator is an individual who has met the licensing requirements of 10 CFR 55 and NUREG-1021 for being a reactor operator. These requirements include:

A reactor operator is licensed to manipulate the controls of a nuclear reactor which may alter reactivity and change the power level. Typically, this means that a reactor operator is qualified to remotely operate control rods and other remote actions required to control the reactor as desired (within regulatory requirements).

Senior reactor operator

A senior reactor operator is an individual who has met the licensing requirements of 10 CFR 55 and NUREG-1021 for being a senior reactor operator. These requirements are similar to the requirements for a reactor operator, except:

A senior reactor operator is licensed to manipulate the controls of a nuclear reactor and direct others to manipulate controls. A senior reactor operator is the senior watch stander in a control room and is responsible for directing the operation of the nuclear reactor as desired (within regulatory requirements). They also are licensed to perform fuel movement/core alterations within the reactor vessel (only SRO and Limited SROs are allowed to do this).

A senior reactor operator licensee (like aviation pilots and masters of ships at sea) is authorized by law to depart from regulations during emergencies. 10CFR50.54(x) states they may "take reasonable action that departs from a license condition or a technical specification (contained in a license issued under this part) in an emergency when this action is immediately needed to protect the public health and safety and no action consistent with license conditions and technical specifications that can provide adequate or equivalent protection is immediately apparent." and 10CFR50.54(y) "Licensee action permitted by paragraph (x) of this section shall be approved, as a minimum, by a licensed senior operator, or, at a nuclear power reactor facility for which the certifications required under Sec. 50.82(a)(1) have been submitted, by either a licensed senior operator or a certified fuel handler, prior to taking the action."

The only other person who may manipulate the controls of a US civilian nuclear power reactor is an individual who:
