pyMAISE.datasets.load_fp()[source]

Load fuel performance data. This data set consists of 13 inputs:

  • fuel_dens: fuel density \([kg/m^3]\),

  • porosity: porosity,

  • clad_thick: cladding thickness \([m]\),

  • pellet_OD: pellet outer diameter \([m]\),

  • pellet_h: pellet height \([m]\),

  • gap_thickness: gap thickness \([m]\),

  • inlet_T: inlet temperature \([K]\),

  • enrich: U-235 enrichment,

  • rough_fuel: fuel roughness \([m]\),

  • rough_clad: cladding roughness \([m]\),

  • ax_pow: axial power,

  • clad_T: cladding surface temperature \([K]\),

  • pressure: pressure \([Pa]\),

and four outputs:

  • fis_gas_produced: fission gas production \([mol]\),

  • max_fuel_centerline_temp: max fuel centerline temperature \([K]\),

  • max_fuel_surface_temperature: max fuel surface temperature \([K]\),

  • radial_clad_dia: radial cladding diameter displacement after irradiation \([m]\),

with 400 data points. This data is case 1 from [RK20] which is based on the pellet-cladding mechanical interaction (PCMI) benchmark. The 13 inputs were uniformly randomly sampled independently within their uncertainty bounds and simulated in BISON. The rod response was recorded in four outputs.

Returns:

  • data (xarray.DataArray) – Raw fuel performance data.

  • inputs (xarray.DataArray) – 13 inputs.

  • outputs (xarray.DataArray) – 4 outputs.
