Japan Atomic Energy Agency (JAEA) proposed a draft safety requirement, which consists of the requirements for constructing a H$$_{2}$$ plant under conventional chemical plant regulations as well as the requirements for collocation of a nuclear facility and a H$$_{2}$$ plant. One of the key requirements is to maintain reactor normal operation condition during every possible condition in the H$$_{2}$$ plant. In order to show that the requirement can be reasonably achieved, a system analysis code is validated with the HTTR experimental data obtained in January 2015. The validated code is applied for the evaluation of a postulated abnormal event in H$$_{2}$$ plant to be connected to the HTTR. The results showed that the evaluation items such as reactor power and reactor outlet coolant temperature do not exceed evaluation criteria. As a conclusion, a feasibility of H$$_{2}$$ plant construction under non-nuclear regulations is validated by showing that the stable reactor operation can be achieved against temperature transients induced by abnormal conditions in the H$$_{2}$$ plant.
