【考案の詳細な説明】
本考案は主として、沸騰水型原子力発電所の放射性気体
廃棄物処理設備に係わり、原子炉水の放射線分解によっ
て生じる水素および酸素の除去に用いられている酸水素
再結合器に関するものである。[Detailed description of the invention] This invention mainly relates to radioactive gas waste treatment equipment for boiling water nuclear power plants, and is used for oxyhydrogen recombination to remove hydrogen and oxygen generated by radiolysis of reactor water. It is related to vessels.
沸騰水型原子力発電所の放射性気体廃棄物処理系は第１
図に示すフローになっている。The radioactive gas waste treatment system of a boiling water nuclear power plant is the first
The flow is shown in the figure.
原子炉水の放射線分解によって生じた水素、酸素は主復
水器１の漏洩空気とともに空気抽出器２により主復水器
より抽気され、空気抽出器の駆動蒸気により、爆鳴気限
界以下に希釈された後、再結合器３で触媒反応により、
酸素、水素は水蒸気となる。Hydrogen and oxygen generated by radiolysis of reactor water are extracted from the main condenser by an air extractor 2 along with leaked air from the main condenser 1, and diluted to below the detonation limit by the driving steam of the air extractor. After that, by a catalytic reaction in the recombiner 3,
Oxygen and hydrogen become water vapor.
水蒸気は排ガス復水器４によＦ月疑縮され除去される。The water vapor is condensed and removed by the exhaust gas condenser 4.
次に酸素、水素、水蒸気を除去された放射性排ガスは半
減期の長いＫｒ、 Ｘｅを活性炭吸着塔５により減衰さ
れた後、排気筒６より大気に放出される。Next, from the radioactive exhaust gas from which oxygen, hydrogen, and water vapor have been removed, Kr and Xe, which have long half-lives, are attenuated by an activated carbon adsorption tower 5, and then released into the atmosphere from an exhaust stack 6.
再結合器前後においては、水素の爆鳴気限界以下になる
様、大量の水蒸気で希釈されているが、排カス復水器以
降では水蒸気が除去されるため、排ガス復水器以降で水
素の爆発の恐れがない様にするため、再結合器は高い触
媒反応度が要求され再結合器下流の水素濃度は非常に少
なくなるようにしなければならない。Before and after the recombiner, hydrogen is diluted with a large amount of water vapor so that it is below the detonation limit, but since the water vapor is removed after the exhaust gas condenser, hydrogen is diluted after the exhaust gas condenser. To avoid the risk of explosion, the recombiner must have a high catalytic reactivity and the hydrogen concentration downstream of the recombiner must be very low.
再結合器の従来構造の一例を第２図に示す。An example of a conventional structure of a recombiner is shown in FIG.
触媒１８は触媒サポート１９の上に充填される。Catalyst 18 is packed onto catalyst support 19 .
この構造では、再結合器内での充填作業となるため、充
填作業性が悪いという欠点がある。This structure has the disadvantage that the filling work is performed inside the recombiner, and therefore the filling work is difficult.
この欠点を解消する構造として、第３図に示すように、
触媒１８を触媒カートリッジ１７に充填し、再結合器内
に挿入する方法がある。As shown in Figure 3, a structure to eliminate this drawback is as follows.
There is a method of filling the catalyst cartridge 17 with the catalyst 18 and inserting it into the recombiner.
この構造では、触媒は触媒製造工場で、カートリッジに
充填できるため、カートリッジ壁面と触媒との間隙を少
なくすることができ、又、ゴミや空気中の不純物が触媒
に付着するのを少なくすることができる。With this structure, the catalyst can be filled into the cartridge at the catalyst manufacturing factory, which reduces the gap between the cartridge wall and the catalyst, and also reduces the adhesion of dust and impurities in the air to the catalyst. can.
更に、触媒の挿入、引出しか゛容易に出来るという利点
か゛ある。A further advantage is that the catalyst can be easily inserted and withdrawn.
しかし、カートリッジのサポーＩ・２１とサポート２２
とをボルトで゛固定するため、サポー１−２１．２２の
間及び゛、ボルト穴からリークか生じる。However, the cartridge support I/21 and support 22
Since these are fixed with bolts, leakage occurs between the supports 1-21 and 22 and from the bolt holes.
排ガス復水器以降で爆発の危険がない様にするためには
、リーク量は１０４分の１以下に押える必要があるが、
上記構造では、リーク量を少なくすることが不可能であ
る。In order to prevent the risk of explosion after the exhaust gas condenser, the leakage amount must be suppressed to 1/104th or less.
With the above structure, it is impossible to reduce the amount of leakage.
又、酸素と水素は発熱反応であるため、再結合器は約３
００℃から４００℃の高温にさらされるため、接着付等
で間隙を充填することはできない。Also, since oxygen and hydrogen are an exothermic reaction, the recombiner is approximately 3
Since it is exposed to high temperatures ranging from 00°C to 400°C, it is not possible to fill the gap with adhesive or the like.
本考案の目的は、触媒をカートリッジに充填した構造の
