This map shows countries with a medium research reactors utilisation rate (country averaged).

This database contains 81 research reactors with a medium utilisation rate distributed over 34 Member States.

The utilisation rate is determined by the Effective Weeks (EW=7days*24hours of operation) of utilisation per year. This database categorises research reactors as follows:

• low utilisation rate reactor (≤ 4 EW)
• medium utilisation rate reactor (>4 EW and ≤ 20 EW)
• high utilisation rate reactor (> 20 EW)

Underutilisation of research reactors world wide remains an important issue.
