Absolutely calibrated measurements of the neutron yields which need to cover both D-D and D-T phase of the international thermal-nuclear experimental reactor(ITER)are impor- tant for the evaluation of fusion power and fusion gain Q in D-D and D-T operations.This paper describes the in-situ calibration techniques and methods,the neutron sources including ~(252)Cf and neutron generator for calibration,the preliminary accuracy assessment and the error analyses.In addition,some difficult problems regarding the in situ calibration for the neutron flux monitor (NFM)on ITER are presented and discussed.
