PWR-core　fuel　management　code　system　NECP-Bamboo　has　been　validated　by　about　one　hundred　commercial　PWR-core　cycles　including　both　the　Second　and　Third　Generations　such　as　Chinese　Nuclear　Power　CNP300　and　CNP600,　Chinese　Pressurized　Reactor　CPR1000　and　ACPR1000,　France　Framatome　M310　and　European　Pressurized　Reactor　(EPR),　USA　Westinghouse　AP1000,　Chinese　CAP1400　and　Hualong-1,　etc.　Among　those,　the　last　four　belong　to　the　Third　Generation　PWRs.　Besides,　BEAVRS　is　the　first　worldwide　well-known　international　benchmark　that　provides　a　complete　two-cycle　description　of　a　commercial　PWR-core,　including　detailed　operating　data　and　measurements,　while　the　Unit　1　of　Sanmen　Nuclear　Power　Plant　(NPP)　in　mainland　China　is　the　worldwide　first　AP1000　core.　Thus,　in　this　paper,　measurements　of　these　two　PWR-cores　were　chosen　to　validate　the　code　NECP-Bamboo,　including　critical　boron　concentration　(CBC),　control　rod　worth,　temperature　coefficient,　detector　response　and　boron　letdown　curve.　Satisfying　agreements　have　been　found　between　the　simulation　with　NECP-Bamboo　and　the　corresponding　measurements.　©　2021　Elsevier　B.V.
