Description
Изобретение касаетс защиты металлов от коррозии, в частности кип щего дерного реактора.The invention relates to the protection of metals from corrosion, in particular a boiling nuclear reactor.
Известен способ защиты от коррозии дерных кип щих реакторов, основанный На подавлении образовани радиолитического кислорода путем введени в теплоноситель или замедлитель гидразина ,A known method of corrosion protection of nuclear boiling reactors, based on suppressing the formation of radiolytic oxygen by introducing into the coolant or moderator hydrazine,
Однако гидразин вл етс токсичным веществом, летучесть которого с ростом температуры значительно возрастает .However, hydrazine is a toxic substance whose volatility increases significantly with increasing temperature.
Кроме того, продукты радиолиза гидразина состо т из водорода и азота , а работа с большими объемами водорода в случае водного реактора св зана с опасностью взрыва.In addition, the radiolysis products of hydrazine consist of hydrogen and nitrogen, and working with large volumes of hydrogen in the case of an aqueous reactor is associated with an explosion hazard.
Целью изобретени вл етс повышение взрывобезопасности.The aim of the invention is to increase explosion safety.
Дл проведени радиолитического кислорода примен ют одно- и двухатомные жидкие алифатические спирты, For radiolytic oxygen, mono- and dihydric aliphatic alcohols are used.
Поскольку вышеуказанные спирты вл ютс нелетучими жидкост ми возможно их применение дл повьппени взрывобезопасности при работе реактора не только в двухконтурньгх, но и в одноконтурных реак.торах.Since the above alcohols are nonvolatile liquids, it is possible to use them in order to ensure explosion safety when operating the reactor not only in double circuits, but also in single loop reactors.
Использование названных вьш1е спиртов существенно не мен ет физики реактора , так как они по своим нейтрон- но-физическим характеристикам занимают промежуточное положение между легкой и т желой водой.The use of the alcohols mentioned above does not significantly alter the physics of the reactor, since, by their neutron-physical characteristics, they occupy an intermediate position between light and heavy water.
Предлагаемые жидкие одно- или двухатомные алифатические спирты хорошо смешиваютс с водой, получающиес смеси вл ютс пожаробезопасными и взрывобезопасными.The proposed liquid mono- or dihydric aliphatic alcohols are well mixed with water, the resulting mixtures are fireproof and explosion-proof.
Конкретную реализацию способа можно осуществить, например, добавлением метанола, этанола, пропанола или этиленгликол в воду, вл ющуюс замедлителем или теплоносителем дерного кип щего реактора. Добавление спиртов в количестве 10 т10 моль/л полностью подавл ет образование кислорода в воде при радиолизе. Растворы вьш1еуказанных спиртов в воде облучают на реакторе ТВР при мощности дозы 5 х X 10 рад/с до 72 Мрад,A specific implementation of the method can be carried out, for example, by adding methanol, ethanol, propanol or ethylene glycol to water, which is a moderator or coolant of a nuclear boiling reactor. The addition of alcohols in an amount of 10 t 10 mol / l completely suppresses the formation of oxygen in water during radiolysis. Solutions of the above indicated alcohols in water are irradiated on a TBP reactor at a dose rate of 5 x 10 rad / s up to 72 Mrad,
Дл серии облучений в присутствии воздуха (аэрированные растворы) в кварцевые ампулы емкостью до 4 мл помещают по 2 мл каждого раствора -и ампулы запаивают, В другой серии провод т удаление кислорода путем многократного повторени откачки замороженного раствора (диаэрированный раствор ) , Анализ газообразных продуктов провод т на хроматографе ХИ-63.For a series of irradiations in the presence of air (aerated solutions), 2 ml of each solution are placed in quartz ampoules with a capacity of up to 4 ml and the ampoules are sealed. In another series, oxygen is removed by repeatedly pumping out the frozen solution (aerated solution). Analysis of gaseous products t on the chromatograph CI-63.
