与日本核数据委员会合作编写了《日本评价核数据图书馆》第四版。在新的库中，重点放在改进裂变产物和少量锕系元素数据上。为了评估裂变产物和少量放线素的截面，开发了两个核模型代码。获得了适用于较宽质量和能量区域的耦合通道光学模型参数，用于核模型计算。通过考虑实验数据或邻近核的系统分布，仔细检查了放线素的热截面。大部分的裂变截面是由实验数据得出的。同时对10 keV以上重要铀和钚同位素的裂变截面进行了评价。对以前的JENDL-3.3库中未包含的30种裂变产物核素进行了新的评估。对轻元素和结构材料的数据进行了部分重新评估。此外，协方差估计主要针对放线素。新库以JENDL-4.0的版本发布，数据可以从日本原子能机构核数据中心的网站上检索。
The fourth version of the Japanese Evaluated Nuclear Data Library has been produced in cooperation with the Japanese Nuclear Data Committee. In the new library, much emphasis is placed on the improvements of fission product and minor actinoid data. Two nuclear model codes were developed in order to evaluate the cross sections of fission products and minor actinoids. Coupled-channel optical model parameters, which can be applied to wide mass and energy regions, were obtained for nuclear model calculations. Thermal cross sections of actinoids were carefully examined by considering experimental data or by the systematics of neighboring nuclei. Most of the fission cross sections were derived from experimental data. A simultaneous evaluation was performed for the fission cross sections of important uranium and plutonium isotopes above 10 keV. New evaluations were performed for the thirty fissionproduct nuclides that had not been contained in the previous library JENDL-3.3. The data for light elements and structural materials were partly reevaluated. Moreover, covariances were estimated mainly for actinoids. The new library was released as JENDL-4.0, and the data can be retrieved from the Web site of the JAEA Nuclear Data Center.
