西安交通大学核工程计算物理实验室（Nuclear Engineering Computational Physics Laboratory, 简称NECP实验室）成立于2004年，其前身为1958年成立的反应堆物理研究小组。

NECP实验室长期从事核数据加工与宏观检验、先进数值计算方法研究与工业软件研发、先进核反应堆设计、反应堆运行技术开发等方面的应用基础研究，先后承担了包括国家“973”、“863”、HN开发项目、重点研发计划、自然科学基金、预研等国家级科研项目50余项，发表SCI论文200余篇，获授权发明专利100余项、软件著作权70余项，获国家级、省部级科技奖励10余项，包括国家技术发明二等奖、国家科技进步三等奖等。

实验室基于数十年来在核反应堆物理数值计算方法方面的研究成果，开发了20余套适用于各类堆型的核反应堆物理分析软件，其中代表性软件产品包括：多功能核数据处理程序“NECP-Atlas”、先进压水堆核设计和堆芯分析程序“NECP-Bamboo”、先进反应堆物理分析程序“NECP-SARAX”、数值反应堆高保真物理分析程序“NECP-X”、蒙特卡罗屏蔽分析程序“NECP-MCX”、确定论屏蔽分析程序“NECP-Hydra”等，软件成果已在我国华龙一号、示范快堆等多个国家重点工程项目中获得成功应用。

NECP实验室拥有教授7人（包括客座教授1人）、副教授4人、专职科研人员2名，其中包括国务院学科评议组成员、863项目首席科学家、国务院特殊津贴获得者、国家级领军人才、国家青年人才、优秀青年基金获得者、国际期刊Annals of Nuclear Energy主编（SCI）、教育部新世纪人才、中国科协青年托举人才和博士后创新人才等。此外，实验室现有在读硕士/博士研究生140余名。近年来，实验室为我国核工业培养了150余名研究生，他们已成长为各大核电集团、研究院所或GF单位的领军人才和技术骨干。实验室在国际HN领域内享有盛誉，与MIT、密歇根大学、北卡州立大学、韩国UNIST、UC-Berkeley等国际知名大学建立了紧密合作关系。

The Nuclear Engineering Computational Physics (NECP) laboratory of Xi'an Jiaotong University was founded in 2004, born from its predecessor, the Reactor-Physics Research Group which was established in 1958.

The research and development of NECP covers nuclear-data processing, reactor physics numerical computation, advanced nuclear energy system design and development, transmutation of high-level radioactive waste and nuclear-fuel-cycle analysis, etc. These researches are funded by more than 50 national projects and more than 100 commercial projects. Impressive achievements have been accomplished including more than 170 SCI papers, more than 80 patents and more than 70 software copyrights. Consequently, NECP has been awarded more than 10 national and provincial awards including the Second Prize of National Technological Invention Award and the Third Prize of National Science and Technology Progress Award.

Based on the fundamental research achievements, more than 20 pieces of reactor physics analysis software have been developed for various types of nuclear reactors, including NECP-Atlas for multifunctional nuclear-data processing, NECP-Bamboo for advanced PWR nuclear design and core analysis, NECP-SARAX for fast-spectrum-reactor core design and analysis, NECP-X for high fidelity numerical reactor simulation, NECP-MCX and NECP-Hydra for shielding analysis, based on stochastic and deterministic theory respectively.

In NECP, there are a galaxy of highly qualified researchers including 7 professors (including 1 guest professor), 4 associate professors and 2 assistant researches. Among those, there is a member of the discipline evaluation group of the State Council, a chief scientist of 863 National Project, a winner of Excellent Youth Fund, an executive editor of Annals of Nuclear Energy, a New Century Talent issued by the Ministry of Education, etc. In recent years, more than 100 post-graduate students have graduated from NECP and they have become leading talents and technical backbones in Chinese nuclear industry, research institutes and national defense departments. NECP enjoys a high reputation in both domestic and international nuclear energy fields. Close cooperation has been established with many internationally famous universities including MIT, University of Michigan, North Carolina State University, UNIST (South Korea), UC Berkeley, etc.
