Definitions
- the first prior art relating to hydrogen injection is disclosed in Japanese Patent Application Laid-Open No. 4-274800. Hydrogen and alkali are injected into the primary cooling system of a nuclear reactor to suppress corrosion of materials and reduce the dose rate of the main steam system. Techniques for trying are described. The publication also states that the PH of the liquid phase becomes alkaline by the injection of the alkali, thereby reducing the rate of transfer of radioactive nitrogen to the gas phase.
- the reactor operating method for controlling the pH of reactor water of a boiling water reactor to an alkaline side and injecting hydrogen into the reactor water to operate the reactor
- the room temperature pH of the water is controlled within the range of 7 ⁇ pH ⁇ 8.5 through one operation cycle, and the hydrogen concentration of the reactor water is controlled in the operation cycle except for a short period during the rated operation. It is controlled within the range of 300 to 100 ppb for most of the time, and increases to the range of 100 to 200 ppb in the short period of the rated operation.
- the room temperature pH of the reactor water is controlled within the range of 8.5 ⁇ pH ⁇ 9 at the beginning of the start-up operation of one operation cycle, and By controlling the pressure within the range of 7 ⁇ pH ⁇ 8.5 until the post-stop operation, the effective oxygen concentration of the reactor water can be effectively reduced, and the generation and progress of SCC can be effectively suppressed. Also in the fourth and fifth inventions, similar effects can be obtained by appropriately selecting a relatively high level and a relatively low level of the room temperature pH.
- Formula 2 is a recombination reaction of hydrogen peroxide has the formula is a recombination reaction of oxygen Response is slower than 1. For this reason, low-concentration hydrogen peroxide is present in the reactor water during hydrogen injection.
- the dose rate of the main steam system is increased.
- the room temperature pH of the reactor water is too high (for example, 9 or more)
- the amount of radioactive substances such as 24 Na in the reactor water increases, which accompanies the steam and reduces the dose rate of the main steam system.
- fuel cladding corrosion may accelerate.
- the room temperature pH of the reactor water within a weak alkaline range (7 ⁇ pH ⁇ 9) as in the first and second inventions, the required hydrogen can be reduced. Since the injection amount (hydrogen concentration) can be reduced, the dose rate of the main steam system can be reduced as compared with the case where weak alkaline control of PH is not used together.
- FIG. 6 is a diagram schematically showing a temporal change of the pH of the reactor water and the tip of the crack in the operating method of the second embodiment.
- the reactor water temperature and reactor pressure rise due to nuclear heating of the fuel, and reach the rated operating state.
- the pH of the reactor water is maintained at about 8.
- start-up sequences such as the start-up of the turbine and the insertion of a generator, the reactor power is increased to reach the rated power. At this point, start-up operation is completed.
