Balance-of-plant systems

This main group of characteristics provides information on conventional plant systems used to generate electricity. 

This group of characteristics specifies the main component of the conventional plant, the steam turbine used to drive the electrical generator. 

Type - the turbine type, based on the main steam parameters at the turbine inlet. Data providers should choose the appropriate option from the multiple-choice menu saturated steam condensing turbine, superheated steam condensing turbine. 

Number of turbine-generators per unit/reactor - the number of turbines installed at the reactor unit to generate the rated unit power. 

Number of HP cylinders per turbine - the number of high-pressure parts of the turbine. The HP cylinder (turbine) is the introductory part of the main turbine closest to the main steam inlet. It consists of a set of HP wheels, usually in a double-flow configuration.

The GT-MHR uses a direct Brayton (gas turbine) cycle for the generation of electricity. As a result, the complex and expensive balance of plant systems required by steam cycle plants are not needed for the GT-MHR. 

Reduce costs for design, operation and maintenance by integrating nuclear supply systems and balance of plant systems into a unified control complex design, using standard components and solid state equipment, simplified field installation by extensive use of multiplexing including fibre optic links where isolation is required. 

The control complex contains all of the protection, monitoring, and control systems necessary for the safe and efficient operation of the nuclear and balance of plant systems. The control complex is based on ABB-Combustion Engineering s Nuplex 80+ Advanced Control Complex. It is comprised of ...

KALIMER is a pool-type liquid metal-cooled reactor that has four intermediate heat exchangers (IHXs), four electromagnetic-type primary coolant pumps. In the KALIMER conceptual design [3], focus has been on the nuclear steam supply system (NSSS) and essential BOP (Balance of Plant) systems. The ultimate objectives for the KALIMER conceptual design are to make it safer, more economical, more resistant to nuclear proliferation, and yield less impact on the environment. Figure 1 represents the sehematie of the KALIMER NSSS. 

The data acquisition systems will be replaced and extended, e.g. the number of the measurements as well as the acquisition rate are increased. Additionally the balance of plant system will be replaced and is now computer controlled.
