The new Act established two separate institutions namely Sri Lanka Atomic Energy Board (SLAEB) and Sri Lanka Atomic Energy Regulatory Council (SLAERC). SLAEB has been assigned the responsibilities of promoting and facilitating the peaceful applications of Nuclear Science and Technology for socio-economic development efforts while SLAERC is assigned for regulatory functions. The SLAEB has been fulfilling its functions in order to accomplish its objectives while gradually acquiring the distinctive technical competences required. The newly established SLAEB carries out qualitative, dedicated work in advancing cooperation in the technical areas, facilitating coordination of technical assistance in addition to performing other mandated tasks.
