Multi modulation

When doing probabilistic modeling for safety verification purposes for a PLC, the modeler must identify what portion of the PLC is being used for the each safety instrumented function. Consider the functional subsystems of a typical single channel (lool) multi-module PLC (Figure 10-4). 

The whole Primary Circuit contained in the reactor vessel is a feature which leads to a multi-module NPP configuration suitable for large interconnected electrical grids.

Many of the concepts presented in this report incorporate modular approach to reactor design, which allows building multi-module plants of higher overall capacity with an option of incremental capacity increase. Such possibility is indicated in Table 2 and outhned in more detail in the corresponding annexes. 

The MASLWR reactor at 35 MW(e) is a natural circulation PWR derivative with integral steam generators and cogeneration capability, see Fig. 3. Each 35 MW(e) plant is modularized for delivery in three shippable components reactor, balance of plant, and condenser. It is intended that multiple MASLWR power plant modules of 35 MW(e) each will be clustered to form a multi-module power plant of up to 1050 MW(e) total output. For refuelling, the reactor components themselves are taken out and returned to the factory on a 5-year interval. 

For operation, all transportable units of the BN GT-300, including the turbo-generator, auxiliary electric machinery and others, are placed into a special building capable of withstanding an aircraft crash or a terrorist attack. Fig. XVIII-1. The same approach, i.e., providing shelter for the main equipment, would be applied for multi-module BN GT plants.

The development and deployment of commercial GT-MHRs is based upon leveraging an ongoing international project to develop and deploy a multi-module GT-MHR designed to consume excess weapons grade plutonium in the Russian Federation, see Annex XV. 

The development of a multi-module Gas Turbine - Modular Helium Reactor (GT-MHR) for excess weapons grade plutonium consumption in the Russian Federation in ongoing within an international project that pools together major efforts of the Russian Federation and the USA. The institutions involved in the R D, design and deployment of the plutonium consumption GT-MHR include the following ... 

Although the initial demonstration unit will be a single PBMR module, the commercialization strategy is to provide complete plants that incorporate eight, four or two modules. An eight module plant would provide an electricity power block of 1320 MW(e). This multi-module business strategy relies heavily on standardization. Plant modularization and system/component standardization are key requirements of the PBMR (Pty) Ltd developers for the commercialization of the PBMR. 

Incremental capacity addition The GT-MHR can be deployed as incremental 268 MW(e) modules in a multi-module site application, with common auxiliaries and central control of up to 4 modules for a total capacity of 1145 MW(e). This allows sequencing of new capacity additions to more closely match demand while obtaining the economic benefits of large-scale generation as the capacity expands. 

TABLE XXVI-2. COMPARISON OF ESTIMATED OVERNIGHT CAPITAL COST (2002 US /KW(e)) OF THE AHTR-IT AND AHTR-HT, AS A PERCENTAGE OF THE COSTS OF THE S-PRISM AND GT-MHR (WITH MULTI-MODULE OUTPUT OF 1145 MW(e)) ...
