Wrapping

input: MCNP input files (criticality or shielding)
input parameters syntax
- variable:
```
%(variable_name)
```
- formula:
```
@{formula_expression}
```
input syntax completion and documentation.
output: Monte Carlo k-effective model “mean_keff”, “sigma_keff”, tallies, energy tallies, mesh tallies.
running progress: current volume of output data, or k-effective estimated if “kcode” claculation.

Installation

user side:
- unzip
  plugin-MCNP-ext.zip
  in Promethee installation directory,
- restart Promethee GUI.
server side:
- unzip
  plugin-MCNP-ext.zip
  in Promethee installation directory,
- open shell console, check “Promethee_Install_Path/scripts/mcnp5 Promethee_Install_Path/examples/UO2” creates a “UO2o” file,
- add
```
<CODE name="MCNP" cplugin="plugins/calc/MCNP.cplugin.jar"  command="**Promethee_Install_Path**/scripts/mcnp5" />
```
  line in calculator.xml file inside ”<calculator>” tag,
- wait for configuration refresh (5 s. if calculator is free).
