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 mobile control room is designated as particularly in high risk facilities, such as a nuclear power station or a petrochemical facility. [further explanation needed] It can provided a guaranteed life support for the anticipated safety control.
The RCPS system consists of 211 movable control rods. Both systems, however, have deficiencies, most noticeably at low reactor power levels. The PPDDCS is designed to maintain reactor power density distribution between 10 and 120% of nominal levels and to control the total reactor power between 5 and 120% of nominal levels.
The B&W mPower control room design is intended to optimize licensed reactor operator staffing levels by utilizing state-of-art, human-focused design principles to reduce the potential for errors.
Fast neutron activation had occurred to various materials in the room, indicating a nuclear power excursion unlike a properly operating reactor. In a thermal-neutron reactor such as SL-1, neutrons are moderated (slowed down) to control the nuclear fission process and increase the likelihood of fission with U-235 fuel. Without sufficient ...
The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in the reactor entering an unsafe operating condition.
Control rods are a series of rods that can be quickly inserted into the reactor core to absorb neutrons and rapidly terminate the nuclear reaction. [2] They are typically composed of actinides, lanthanides, transition metals, and boron, [3] in various alloys with structural backing such as steel.
1943 Reactor diagram using boron control rods. Control rods are inserted into the core of a nuclear reactor and adjusted in order to control the rate of the nuclear chain reaction and, thereby, the thermal power output of the reactor, the rate of steam production, and the electrical power output of the power station.
