BS EN 60965:2016

What is BS EN 60965-Supplementary control room for reactor nuclear about? 

BS EN 60965 is an International Standard that establishes requirements for the Supplementary Control Room provided to enable the operating staff of nuclear power plants to shut down the reactor, where previously operating, and maintain the plant in a safe shut-down state in the event that control of the safety functions can no longer be exercised from the Main Control Room, due to unavailability of the Main Control Room or its facilities. 

BS EN 60965 also establishes requirements for the selection of functions, the design and organization of the human-machine interface, and the procedures which shall be used systematically to verify and validate the functional design of the supplementary control room. 

BS EN 60965 follows the principles of IAEA Specific Safety Requirements SSR-2/1 and IAEA Safety Guide NS-G-1.3. 

Who is BS EN 60965-Supplementary control room for reactor nuclear for? 

BS EN 60965 on nuclear power plants supplementary control rooms is useful to: 

• Nuclear power stations 
• Atomic energy agencies 
• Atomic research organizations 
• Nuclear power plants electrical systems and equipment manufacturers 
• Operators of NPP, systems evaluators, and licensors 
• Nuclear safety authorities 
• Regulatory authorities 

Why should you use BS EN 60965-Supplementary control room for nuclear reactor? 

Because the fission products formed inside the fuel components are radioactive and emit a huge quantity of heat, shutting down is a critical operation. If the main control room is not available, then the supplementary control room is used to shut down the reactor. 

BS EN 60965 provides functional design requirements to be used in the design of the supplementary control room of a nuclear power plant to meet safety requirements. 

The guidance in BS EN 60965 ensures the safe design of the supplementary control room is protected against the hazards, including any localized extreme hazards, leading to the unavailability of the main control room. 

What’s changed since the last update? 

BS EN 60965:2016 supersedes BS EN 60965:2011 which is withdrawn. BS EN 60965:2016 includes some technical changes with respect to BS EN 60965:2011. These include: 

• Requirements associated with regular testing of the supplementary control room (SCR) 
• Requirements to assess the time available during which the reactor will be safe but unattended, in order to move from the main control room (MCR) to the SCR and for the SCR to become operational 
• Reference to SSR-2/1 which includes the following new requirements the SCR should be functionally (as well as physically and electrically) separate from the MCR
