Abstract

A differential calorimeter with flux measurement to measure a heat flux emitted by radioactive materials contained in a container, including: a measurement cell including measurement plates distributed around a container reception containment; and a reference cell including reference plates and a reference sample. The reference plates are placed behind the measurement plates from the container when the container is in the reception containment and the reference sample is under the reception containment.

First claim

The invention claimed is:

1. A differential calorimeter with flux measurement to measure a heat flux emitted by radioactive materials contained in a container, comprising:
a measurement cell comprising measurement plates including a first measurement plate on which the container is to be disposed and plural other measurement plates;
a reference cell comprising reference plates and a reference sample;
wherein each reference plate is placed facing a side of a respective measurement plate opposite to a side of the respective measurement plate facing the container when the container is disposed on the first measurement plate, and
wherein the reference sample is under the first measurement plate.

2. A differential calorimeter according to claim 1 , further comprising
a fixed part configured to hold the container and including the first measurement plate and
a moving part configured to be assembled above the fixed part and configured to open to allow the container to be placed on the fixed part.

3. A differential calorimeter according to claim 2 , wherein the fixed part contains the reference sample and at least one reference plate.

4. A differential calorimeter according to claim 2 , wherein the moving part comprises at least one reference plate and at least one measurement plate.

5. A differential calorimeter according to claim 1 , further comprising Peltier elements affixed onto a side of each of the other measurement plates facing a respective reference plate.

6. A differential calorimeter according to claim 1 , wherein each of the other measurement plates faces a different side of the container when the container is disposed on the first measurement plate.
