description
ONR is seeking to engage one of the Technical Support Contractors (TSC) appointed on Lot 1 of its Technical Support Framework.
The TSC is required to develop a thermal hydraulic system code computer model of the UK HPR1000.
| 1) | A pragmatic approach to its development should be taken to ensure the model can be applied to a selection of fault transients without expending unnecessary effort developing redundant capabilities that are not required. |
| 2) | The computer model should utilise a point kinetic approach for the reactor physics for the initial work scope. However, the model should be developed with a view to coupling with the more sophisticated reactor physics model in the final phase. |
| 3) | The computer model should include a basic consideration of containment response. A more detailed containment model is not envisaged at this time but there is value in providing the capability and flexibility to develop and couple such a modelling if containment behaviour emerges as an area of regulatory interest. |
Develop a Core Physics computer model of the UK HPR1000.
| 1) | The TSC will use geometric and isotopic data to derive a set of neutron cross sections for each proposed fuel assembly type as a function of irradiation and other suitable dependencies. Given the proposed fuel loading pattern, this will be used to determine the nominal power distribution for full-power conditions. The nuclear data derived will need to take account of the spectral history of each fuel assembly in the equilibrium core to determine appropriate nuclear data. |
| 2) | The TSC will use the nuclear data produced in 1) to develop a 3D, transient core model suitable for use as part of a wider model for the purposes of fault transient analysis. The adequacy of the predicted steady state performance will be confirmed by comparison against core power-distribution data supplied. |
