Control room for nuclear power plant

A method operating in conjunction with video display units (VDUs) of a reactor control interface wherein the VDUs include a group of safety VDUs and an additional VDU that is not a safety VDU, the method comprising:

• detecting a malfunctioning safety VDU, the remaining safety VDUs being functioning safety VDUs;
• shifting the displays of the functioning safety VDUs to free up one of the functioning safety VDUs wherein the shifting transfers the display of one of the functioning safety VDUs to the additional VDU that is not a safety VDU;
• and
• transferring the display of the malfunctioning safety VDU to the functioning safety VDU freed up by the shifting.

A non-transitory storage medium storing instructions executable by an electronic data processing device in communication with a video display unit (VDU) to perform a method comprising:

• displaying a home screen representing a nuclear power plant, the home screen including:
• blocks representing functional components of the nuclear power plant including at least (i) blocks representing functional components of a normal heat sinking path of the nuclear power plant and (ii) blocks representing functional components of at least one remedial heat sinking path of the nuclear power plant, and
• connecting arrows of a first type connecting blocks that are providing the current heat sinking path wherein directions of the connecting arrows of the first type represent the direction of heat flow along the current heat sinking path;
• and
• in response to the nuclear power plant transitioning to a different heat sinking path, updating the connecting arrows of the first type by deleting and adding connecting arrows of the first type so that the updated connecting arrows of the first type represent the different heat sinking path.
