ジャーナル フリーFitness-For-Service (FFS) assessment of pressure equipment in petroleum and petrochemical plant can be used to demonstrate the structural integrity of pressure equipment that may contain a flaw or damage. If the equipment includes a damaged component with a compressive stress field under applied design loads, assessment for protection against collapse from buckling is needed. There has been, however, little study on buckling assessment for general tower with metal loss subjected to seismic loadings in petroleum and petrochemical plant.
In this study, relationship between metal loss shape and buckling moment was investigated for general tower in the plant using finite element analysis (FEA) . In addition, the results of FFS assessment using API 579-1⁄ASME FFS-1 (API⁄ASME FFS) were validated by FEA. The results of validation indicated that API⁄ASME FFS assessment provides conservative results in the case of localized metal loss. Finally, a more accurate assessment procedure for localized metal loss was proposed.抄録全体を表示PDF形式でダウンロード (1374K) -

ジャーナル フリーThe purpose of the research program is to provide review manuals and technical database for Ageing Management Technical Evaluation Reports performed by licensees of spent fuel reprocessing plants in accordance with ordinance on Periodic Safety Review.
Research programs have been conducted based on a contract with well-equipped organization since F. Y. 2006. One experimental subjects on ageing phenomena listed below in this program for the technological assessment of TOKAI plant, which have experienced many corrosion problems. TOKAI plant is the pilot plant for reprocessing service commissioned in Dec. 1980 and shifted to R&D in Apr. 2006.

ジャーナル フリーSeveral tens of definitions for the ductile to brittle transition temperature (DBTT) have been proposed so far, corresponding to various test methods on toughness of steels. The correlations between those DBTTs estimated empirically are not satisfactory. The present paper points out an important role of carbon content through “strain toughening effect” in the correlations between DBTTs, especially between fracture toughness and Charpy impact toughness.抄録全体を表示PDF形式でダウンロード (87K)
