Nuclear hydrogen production system comprising an intermediate loop keeping continuous operation of a nuclear hydrogen reactor

摘要

The present invention relates to a nuclear hydrogen producing system comprising a hydrogen production nuclear reactor intermediate grid which allows consistent nuclear reactor operation. More specifically, the nuclear hydrogen producing system comprises: an ultra-high temperature gas unit; a first heat exchange unit; a second heat exchange unit; and a first closed loop to allow a first operation fluid to flow so that heat produced by the ultra-high temperature gas unit can be sequentially transmitted to the first heat exchange unit and the second heat exchange unit which are arranged in series. The first heat exchange unit includes: a first heat exchanger; a sulfur trioxide decomposer; a sulfuric acid decomposer; and a second closed loop to allow a second operation fluid to flow so that heat transmitted from the first heat exchanger can be transmitted to the sulfur trioxide decomposer and the sulfuric acid decomposer. The second heat exchange unit includes: a second heat exchanger; a sulfuric acid evaporator; a hydrogen iodide decomposer; and a third closed loop to allow a third operation fluid to flow so that heat transmitted from the second heat exchanger can be transmitted to the sulfuric acid evaporator and the hydrogen iodide decomposer. According to the present invention, the nuclear hydrogen producing system can reduce the use of the high-price ultra-high temperature heat exchanger by sequentially separating the heat exchangers into the heat exchangers for the ultra-high temperature and the high temperature, thereby reducing the costs, and being constantly operated by operating multiple extra sub-heat exchange units for the ultra-high temperature and the high temperature which are arranged in parallel even though there is a failure in one sub-heat exchange unit. Furthermore, the nuclear hydrogen producing system is able to reduce failures by reducing the burden of a gas circulator and to reduce the costs by using the cheat gas circulator having a small capacity.
