  1. Reactor related • Neutrino flux • Location of Reactor and detector • Interaction spectrum at a detector  Cross section  Target mass • …

  2. How to obtain RENO-specific neutrino flux 1) 핵분열횟수 • Reactor power: 2.73GWth (x 6 reactors) • Mean energy per fission: 각각의 isotope의 mean energy와 fraction 고려  ~ 3.1x1019 fissions /GWth/s  ~ 8.5x1019 fissions /reactor/s 2) Neutrino spectrum per fission • dN/dE : number of neutrinos/MeV/fission from each of four fissile material (PRD70 053011)

  3. Uncertainty from 핵분열횟수 • Reactor power uncertainty • Initial fraction of fission rates: 시간에 따른 핵연료의 연소비가달라짐. • Fission당 방출되는 에너지: recoverable energy can be calculated by ORIGEN code  uncertainty of the number of fission ? • spent fuel rack에서 발생되는 fission은 노심에 비해 무시할만큼 작다고 함. (지성구박사님 발표자료 참고)

  4. Uncertainty from neutrino spectrum per fission • Initial fraction of fission rates: 시간에 따른 핵연료의 연소비가달라짐.  4가지 핵연료의 연소비를fission당 neutrino energy spectrum에 적용하게 되는데 이때 시간에 따라 핵연료의 연소비가 달라지면 중성미자 에너지 스펙트럼이 달라지게 된다.
