Design parameters reactor

In addition to the three temperature levels (TP, MTSR, and TD24), there is another important temperature that at which technical limits of the equipment are reached. This may be due to the resistance of construction materials, or to the reactor design parameter as pressure or temperature, and so on. In an open reacting system, operated at atmospheric pressure, the boiling point is often used. In a closed system, operated under pressure, it may be the temperature on reaching the set pressure of the pressure relief system. 

In addition to the usual reactor design parameters, height of the fluidized bed is controlled by the gas contact time, solids retention time, bubble size, particle size, and bubble velocity. 

For a specific reactor design, parameter B is constant. Raw material costs increase faster than q when q/B >0.1. This is caused by increased feed rate W and increased unconverted Algol in the effluent. The variable production cost can also be expressed in terms of the annual Delos production q ... 

C (2912 F) during depressurized core heat removal by the Reactor Cavity Cooling System (RCCS). Selected reflector elements in both the central and side reflector contain channels for top entry control rods and for nuclear instrumentation. Nominal reactor design parameters are given in Table 4.1-1, and in Section 5.1. 

Caravella et al. (2008) PBMR - ID - Nonisothermal conditions - Plug flow - Membrane completely selective toward H2 permeation - Ergun s equation - Xu and Froment (1989a) The paper pointed out that the reactive/permeative stage distribution has to be considered an important reactor design parameter. 

The reference reactor design parameters are reported in Table 2.2 and the following considerations can be drawn ...

In future works, more detailed and precise definitions of the reactor design parameters in both normal and transient conditions are required. Moreover, more complete database and model-based predictive capabilities for the properties of SiCf/SiC composites irradiated at above 1000°C should be established. In order to use SiCf/SiC in applications of structural components, it is necessary for well-established testing standards and material codes to be in place. In addition, a leak-tightness or a hermetic joining technology with sufficient in-pile and out-of-pile data is also needed.
