The OECD-NEA High Priority Request List (HPRL) is a point of reference to guide and stimulate the improvement of nuclear data for nuclear energy and other nuclear applications. The HPRL is application-driven and the requests are submitted by nuclear data users or representatives of the user's communities. A panel of international experts reviews and monitors the requests in the framework of an Expert Group mandated by the NEA Nuclear Science Committee Working Party on International Nuclear Data Evaluation Cooperation (WPEC). After approval, individual requests are divided in two priority categories only, whereas a third category now includes groups of generic requests in a well-defined area (e.g., dosimetry, standard). The HPRL is hosted by the NEA in the form of a relational database publicly available on the web. This contribution provides an overview of HPRL entries, status and outlook. Examples of requests successfully completed will be given and new requests will be described with emphasis on updated nuclear data needs in the fields of nuclear energy, neutron standards, dosimetry, and medical applications.

Uncertainty components of experimental observables resulting from total and reaction cross section experiments are quantified by identifying the metrological parameters involved in the measurement, data reduction and analysis process. In addition, different methods that can be applied to propagate the covariance of the experimental observables to the covariance of the resonance parameters are discussed and compared. It is demonstrated that the final covariance matrix of the resonance parameters not only strongly depends on the type of experimental observables used in the adjustment process, the experimental conditions and the characteristics of the resonance structure, but also on the method that is used to propagate the covariances. In addition, a special data reduction concept and format is presented, which offers the possibility to store the full covariance information of experimental data in the EXFOR library.

2001年より欧州共同原子核研究機関(CERN)の中性子飛行時間法実験施設(n_TOF)が稼働している。ここでの中性子ビームの特徴、特に高い瞬間強度,広いエネルギー範囲と低バックグラウンドを活かして、天体核物理や基礎物理研究のみならず革新的原子力システム開発分野における中性子反応測定のユニークな実験施設を提供した。この新施設の建設に至った科学的動機について紹介する。
