Abstract: Measurements of activities for 16N and 19O nuclei in the loop water of swimming pool reactor at China Institute of Atomic Energy were carried out. In order to verify the experiment results, a calculation for same purpose was also performed. The results show their coincidence is well in uncertainty range. The evaluated recommendation data for 18O(n, γ)19O reaction cross sections are also given in the paper.
