Participation in a CEC strategy study on nuclear waste transmutation

Objective

This work has first of all as an objective the improvement of the nuclear data base needed for strategy study on nuclear waste transmutation, including inventory calculations. A second objective is the presentation of a contribution to the CEC strategy study, in the form of a paper on transmutation of long-lived fission products. Besides strategy and scenario studies, reactor physics research, and an effort towards small scale demonstrations of transmutation possibilities, the integral program is focused on the nuclear parameters, relevant for transmutation.

Although the ECN, acted as the sole contractor for this contract, there has been a close collaboration in related strategy studies, such as the ones of CEA and Siemens.
The objective of this project is to improve the nuclear database needed for the strategy study on nuclear waste transmutation, including inventory calculations. A contribution to the CEC strategy study will also be made, in the form of a paper on transmutation of long lived fission products.

The European research programme on transmutation of nuclear waste, of which this project is a component, is intended to give contribute to an international effort to evaluate the recycling option of the nuclear waste problem. Besides strategy and scenario studies, reactor physics research, and an effort towards small scale demonstrations of transmutation possiblities, the programme focussed on the nuclear parameters relevant for transmutation, the objectives of this study.

A harmonization has been discussed of three Community contracts, with regard to studies on possibilities to reduce the long-term radiotoxicity of nuclear waste. The ECN proposal is of vital interest, as far as it aims towards common data sets and standardized libraries for relevant cross sections. Also the proposed ECN work on long-lived fission products is considered to be an important contribution to the joint studies.

As a first step the Petten group now has started to adapt codes and libraries (ORIGEN and FISPACT, and especially working libraries of cross sections, nuclear decay constants, and risk data) for reactor physics and burnup calculations. With respect to the work on codes and libraries, the ECN data set will be used. Especially for nuclear data on actinides and long-lived fission products this data set should be improved. Now the most recent European JEF-2 library is being inspected on quality and completeness. As the JEF-1 library is readily available in processed data, it can be used as a back up. There has also been substantial progress in the study of fission product transmutation.
Work programme:

- Preparation of a nuclear data base for actinides and fission products, which is needed for the experimental verification of technological aspects of transmutation.

- Preparation of derived data in order to assess the ORIGEN nuclear data library for transmutation studies.

- Performing sample burn-up calculations for several scenarios with the updated ORIGEN nuclear data library.

- Investigation of possibilities of transmutation of long-lived fission products.
