- •
First detailed neutronic modelling of the ECHUL port cell with ECHUL equipment (including beam lines with diamond windows, the beam lines mounting box, conduit boxes and rails).
- •
Three different bioshield port plug configurations and two different neutron source configurations are investigated.
- •
Radiation Levels are calculated in the port cell, focusing on the position of the diamond window.
- •
The dose rate in the port cell is below the limit for maintenance in the port cell.
- •
The radiation level at the diamond window is very low and should not influence its performance.
