検の頻度を低くでき、作業員の被曝量を低減できる。In this first embodiment, since the condensate storage tank is housed in the waste treatment building, it is possible to downsize or eliminate shielding walls, rain shutters, equipment to prevent salt contamination, heat insulation equipment, etc. The scale of the water storage equipment can be reduced.6 Furthermore, since the condensate storage equipment is not directly exposed to wind, rain, snow, etc., the frequency of maintenance and inspection can be reduced, and the amount of radiation exposure of workers can be reduced.
復水貯蔵槽をライニング槽として設置したので。The condensate storage tank was installed as a lining tank.

ても、コンクリート壁で漏洩を防止できるので、放射性
の復水が建屋外に漏洩することがなく安全性を高めるこ
とができる。Compared to simply installing a cylindrical tank inside a waste treatment building, the space inside the building can be used more effectively. Also,
Even if the lining plate is made thinner, the strength of the concrete wall can be maintained. Even if a leak occurs in the lining plate, the concrete wall can prevent the leak, preventing radioactive condensate from leaking outside the building, increasing safety.
空気調和機排気室が設置されているので、放射化された
空気が廃棄物処理建屋内に流出することがなく、建屋内
の汚染を防止できる。Since an air conditioner exhaust chamber is installed, radioactive air will not flow into the waste treatment building, preventing contamination within the building.
復水貯蔵槽に貯留された復水の熱容量により。Due to the heat capacity of the condensate stored in the condensate storage tank.
廃棄物処理建屋内の温度を一定に保つことが容易になり
、換気空調系機械の負荷を軽減することができる。It becomes easier to maintain a constant temperature inside the waste treatment building, and the load on ventilation and air conditioning system machinery can be reduced.
また、復水貯蔵槽が原子炉建屋内に設置された場合に比
べ、以下に説明する効果がある。Furthermore, compared to the case where the condensate storage tank is installed inside the reactor building, the following effects are achieved.
復水の主な発生源である廃棄物処理設備に近いので、復
水の回収を容易に行なうことができる。Since it is close to waste treatment equipment, which is the main source of condensate, it is easy to collect condensate.
復水貯蔵設備の運転は、廃棄物処理建屋内の操作室から
操作されるので、管理を容易に行なうことができる。Since the operation of the condensate storage equipment is controlled from the control room inside the waste treatment building, management can be easily performed.

ができる。廃棄物処理建屋内は一部を除いてほとんどが
管理区域であるので漏洩が発生した場合も対策を立てや
すく、非管理区域（クリーンエリア）を汚染することが
ないので、安全性を向上できる。Leak detection instruments can be shared with other waste treatment equipment. Most of the inside of the waste processing building is a controlled area, with the exception of a few, so it is easy to take measures in the event of a leak, and the non-controlled area (clean area) will not be contaminated, improving safety.

るので。Since the condensate storage tank handles radioactive fluids, it was necessary to take precautions against leakage and venting the tank storage pit, but since the waste processing building is a controlled area, it can be removed or shared with other equipment. If a condensate storage tank was installed in a reactor building, it would be necessary to consider emergency equipment and a clean area, but most of the waste treatment building is a controlled area.
