Assignment

The Republic of the Union of Myanmar has contacted you with respect to designing a Generation III+ reactor for implementation in their country. Currently the country has a requirement of 4.8 GW which needs to be a stable baseload with a good capacity factor and minimal CO2 production. This power production can be provided by either small modular reactors or large scale nuclear power plant.

Myanmar is currently not a signatory to the Nuclear Non-proliferation Treaty. This maybe a problem regarding which designs can be developed with respect to the reactor fuel, but it is expected that the country will be amenable to operating a fuel  lease strategy to  be able to  run their  reactors. The government  is  very  resistant  to  having  the  Russian  government  bail  them  out  by  building  and operating 4 VVER  1200MW  reactors  and  want  to  develop  their  own  nuclear  infrastructure  and possibly unique reactor design that sets them apart from the rest of the world.

Design a Gen III+ reactor from a selection of materials and determine the k∞ for your selected reactor and fuel composition. Some components you may need to calculate lethargy values for and adapt the resonance escape probability equation. Once you have determined the k∞ use this to calculate the geometric Buckling constant Bg and the dimension of the reactor above which the reactor will be critical. Most thermal nuclear reactors operate with a keff around 1.4-1.6 and then use control rods, chemicalshim or burnable poisons to bring the multiplicity factor closer to 1.

Using the reactor power (MeV·s-1), the average energy released per fission (Ef  = 200-202  MeV), reactor volume (V), and the fuel density cross section (Σf) an approximate neutron flux can be estimated*.

*this also means from a literature-based flux you can calculate what the reactor volume needs to be to attain a particular power.

Considering the reactor components and the size of the reactor your design should not appear that much different from conventional Gen II to Gen IV reactors. There were also previous experimental reactor designs that were developed, such as the organic cooled reactor (OCR) and the molten salt reactor (MSR). You also have a choice between using heat exchangers or having the coolant be the working fluid in your design (PWR vs BWR).
