Application of human reliability analysis in the deterministic safety analysis for nuclear power plants
Autor: Ulf Kahlbom, Jan-Erik Holmberg
Publikováno v: Reliability Engineering & System Safety. 194:106371
Licensing of nuclear power plants relies on safety analyses showing compliance of the design and operation with safety requirements. The safety analyses comprise of both deterministic analyses, where the compliance with deterministic rules shall be s

Risk-informed safety classification of components of auxiliary systems for emergency diesel generators in nuclear power plants
Autor: Jan-Erik Holmberg
Publikováno v: Safety and Reliability – Safe Societies in a Changing World ISBN: 9781351174664
Safety classification of structures, systems and components of nuclear power plants shall be based on the functional importance of the items. One challenge with the nuclear safety classification is that different classification systems are used in di
