Abstract

Laser powder bed fusion (LPBF) technology offers various advantages, making it a promising option for the nuclear industry. This study presents an LPBF-prototyping case for its potential use in the nuclear industry. After optimizing the LPBF process and heat treatment conditions, mechanical tests were performed, including room-temperature and high-temperature tensile and fatigue tests. The samples demonstrated mechanical properties sufficient to replace commercial parts. The bottom grid and bottom nozzle parts of a nuclear fuel assembly were also manufactured using LPBF technology and compared to commercial parts. The high design flexibility of LPBF allowed for innovative structures, resulting in better performance than commercial parts. These research examples support the practical application of additive manufacturing in the nuclear field by providing necessary data for standardization and certification.

期刊介绍： Progress in Nuclear Energy is an international review journal covering all aspects of nuclear science and engineering. In keeping with the maturity of nuclear power, articles on safety, siting and environmental problems are encouraged, as are those associated with economics and fuel management. However, basic physics and engineering will remain an important aspect of the editorial policy. Articles published are either of a review nature or present new material in more depth. They are aimed at researchers and technically-oriented managers working in the nuclear energy field. Please note the following: 1) PNE seeks high quality research papers which are medium to long in length. Short research papers should be submitted to the journal Annals in Nuclear Energy. 2) PNE reserves the right to reject papers which are based solely on routine application of computer codes used to produce reactor designs or explain existing reactor phenomena. Such papers, although worthy, are best left as laboratory reports whereas Progress in Nuclear Energy seeks papers of originality, which are archival in nature, in the fields of mathematical and experimental nuclear technology, including fission, fusion (blanket physics, radiation damage), safety, materials aspects, economics, etc. 3) Review papers, which may occasionally be invited, are particularly sought by the journal in these fields.
