Analisis dan Penentuan Distribusi Fluks Neutron Thermal Arah Aksial dan Radial Teras Reaktor Kartini dengan Detektor Swadaya

ABSTRACT: In  this  paper,  we  analyze  and  compute  distribution  of  thermal  neutron  flux  in  core  of Kartini’s Reactor using “Swadaya” detector, both for axial (function of z) and radial (function r) direction. First, “Swadaya”  detector  is  calibrated  by  activation  plate  method,  which  the  output  from  detector  is  current.  The result of calibration is thermal neutron flux () dependent on current (I) that can be written as    = 4,57x1020I  -2,74x1011.
