The ESARDA working group for Techniques and Standards for Non Destructive Analysis decided to launch 2 international benchmark exercises. The first initiative aims to confront different approaches to Reals evaluation with each other and with measurement results obtained from a well documented experimental set-up. The present contribution discusses briefly the Reals prediction benchmark exercise, the experimental set-up built in PERLA and the conclusions of the inter-comparison is drawn.

In the second initiative the ESARDA-NDA working group decided to work out a benchmark exercise for MCNP on simple geometries typically related to the configurations frequently encountered in safeguards applications. The exercise confronts the simulation results with experimental measurements in different fields as for instance, interaction of fast neutrons with (3)He detectors, moderation, thermal and fast neutron induced fission in Uranium, the effect of lead shielding on neutron transport, etc. The exercise focuses mainly on the use and performance of MCNP. The present contribution deals with the geometric aspects of the benchmark exercise. .
