Nuclear Photoreactions in the Context of a Nuclear Data Review for Radiation Shielding in Advanced Technology Applications

Abstract

Theoretical results are presented on nuclear photoreaction calculations, based on algebraic models of the nuclear structure, relevant to advanced technology applications, mainly in the intermediate energy region, such as those related to accelerator applications, particularly to shielding studies concerning Accelerator Driven Systems (ADS), intense neutron spallation sources and also electron accelerators (including free electron lasers and advanced synchrotron radiation facilities applications) as well as for medical purposes. The present results are discussed within a review of the international co-operation for nuclear data for radiation shielding, carried out at ENEA. In particular, the contributions are presented to the SATIF initiative and to the related co-operation activities on shielding aspects of accelerators and irradiation facilities, according to the NEA Nuclear Science Committee (NSC) advice, to JEFF project and NSC-WPEC relevant activities, concerning microscopic nuclear data evaluation and validation.
