Input description

The ROOSTER input file is an ASCII text file consisting of lines (cards) identified by keywords. It should be named input. The cards are presented in the following sections by examples in alphabetical order of the keywords. All numerical values and upper-case words are specified by users. The low-case words are keywords and should not be changed. The cards are divided in the following categories:

• Control cards
  • # : Comment
  • & : Line continuation
  • signal : User-defined signal
  • solve : Model activation flag
  • t0 : Initial time
  • tend : Integration time set
  • tol : Required solution tolerance
• Core cards
  • betaeff : Effective fractions of delayed neutrons
  • coregeom : Core geometry
  • coremap : Core map
  • dnplmb : Delayed neutron precursor decay time constants
  • mix : Homogeneous mix of isotopes
  • nddir : Nuclear data directory
  • power0 : Initial reactor power
  • stack : Vertical stack of homogeneous mixes
  • tlife : Prompt neutron lifetime
• Fluid cards
  • jun : Dependent junction
  • jun-i : Independent junction
  • jun-i-f : Independent junction with user-defined flowrate
  • jun-i-p : Independent junction with user-defined pump head
  • pipe : Pipe without free level
  • pipe-f : Pipe with free level
  • pipe-t : Pipe without free level with temperature defined by signal
  • thermbc : Thermal boundary conditions
• Solid cards
  • clad : Cladding tube
  • fuel : Fuel column
  • fuelrod : Fuel rod axial levels
  • htstr : Heat structure
  • innergas : Fuel rod inner gas
  • mat : Material
