Based　on　the　conventional　＇two-step＇　scheme　for　the　PWR　fuel　management,　an　advanced　PWR　fuel　management　software　Bamboo-C　has　been　developed　by　the　most　advanced　methodologies　in　the　reactor-physics　field.　Bamboo-C　consists　of　three　main　functional　codes:　LOCUST　code　for　the　heterogeneous　modeling　and　simulation　and　homogenization　calculation　of　2D　assemblies;　SPARK　code　for　3D　core　steady-state　and　transient　analysis;　and　LtoS　code　for　assembly　homogenization　parameter　function,　which　links　LOCUST　and　SPARK.　Bamboo-C　has　all　the　necessary　analysis　functions　for　the　fuel　management　and　nuclear　design　of　PWRs,　mainly　including　the　start-up　physics　tests,　calculations　of　the　neutron-kinetics　parameters,　differential　and　integral　worth　of　rod　cluster　control　assemblies　(RCCAs),　and　power-operation　following　simulation.　Finally,　the　engineering　validations　of　Bamboo-C　have　been　completed　according　to　the　operation　data　from　the　reactors　CNP300,　CNP650　and　CNP1000　designed　by　China　independently.　The　validation　results　show　that　the　errors　between　the　values　of　such　key　parameters　of　cores　as　critical　boron　concentration,　temperature　coefficient,　RCCA　worth,　and　power　distributions,　calculated　by　Bamboo-C,　and　their　measured　values　satisfy　the　corresponding　engineering　criterion　limits.　©　2021,　Editorial　Board　of　Journal　of　Nuclear　Power　Engineering.　All　right　reserved.
