3. DESCRIPTION

BERENICE is an international experimental campaign relative to benchmark measurements of the effective delayed neutron fraction (beta_eff). It consists of two phases:

BERENICE - CORE R2: uranium core with an enrichment of 30% in U-235 with basic cell-type R2.
BERENICE - CORE Pu: plutonium core with a Pu-239 content of 25% with basic cell-type ZONA 2.

The objectives of the measurements are to reduce the uncertainties of the
effective delayed neutron fraction, using different methods:

measurement of natural neutronic flactuations in the core
measurements of alpha-Rossi
measurements of pseudo reactivity of Cf source

BERENICE - CORE R2 Experimental programme
Uranium configuration (cell-type : R2). This phase involves two configurations :

The clean core with 1006 cells,
The core modified by the presence of four large fission chambers with 1036 cells.
This measurement concerns:
The core characterisation such as:

Critical radius
Reactivity of control rods, pilot rod, and peripheral cells
Power normalisation
Temperature effects
and beta_eff specific measurements

U-235 and U-238 fission rate distribution
Cf source worth distribution
Spectral indices
Pile noise, alpha-Rossi, other techniques

BERENICE - CORE Pu Experimental programme
Plutonium configuration (cell-type : ZONA 2). This phase involves two critical configurations BERENICE-Pu/EXP.
The fuel is arranged in concentric zones: UO2-PuO2 with a Pu-240 content of 18% and a Pu content of dioxide of 25%.
This phase involved a clean core with 1111 cells.
The measurements concern :

critical radius
reactivity of control rod
power normalisation
temperature effects
U-235, U-238, Pu-239 and Np-237 fission rate distributions
Cf source worth distribution
Spectral indices
Pile noise, and Cf source worth
