A typical 18-months fuel cycle strategy is introduced in this paper.It deals with the transition towards 18-months reload from the first cycle and reaching equilibrium cycle through the minimum cycles at Ling’ao Phase-II Nuclear Power Station.Cycle length,gadolinium use,loading pattern,as well as main key safety parameters are given.The fulfillment of the study demonstrates the feasibility of launching 18-month reload at Ling’ao phase-II and offers theoretical basis for determining the final fuel management strategy.
