設備の大きさを決める上で、大きなウェイトを占めてい
るため、コストアップの要因となっている。Conventional reactor recirculation pump mechanical seals drain water into an equipment fin/sump inside the containment vessel. The amount of drain generated by this is 10 tons/day, which accounts for 2/3 of the total amount of drain generated as equipment drain inside the containment vessel. In addition, it accounts for 1/4 of the amount of equipment drainage generated at the power plant as a whole (40 tons/day), and it plays a large role in determining the size of waste treatment equipment, so it is a major factor in increasing costs. This is a contributing factor.

The purpose is to reduce excess water discharged outside the system.

ールのパージ排水である。この排水を零にすることによ
り廃棄物処理設備の負荷を軽減し、コスト低減を計る。During normal operation of a nuclear power plant, there are various kinds of equipment drains that are continuously generated, such as containment vessel equipment drains and reactor building equipment drains, but among these, the containment vessel equipment drains generate the most amount of drain. . Approximately 15 tons/day of containment vessel equipment drainage is generated continuously, and the majority of this is purge drainage from the mechanical seals of the reactor recirculation pumps. By reducing this wastewater to zero, we aim to reduce the load on waste treatment equipment and reduce costs.
以下、本発明の実施例を第１図により説明する。Embodiments of the present invention will be described below with reference to FIG.

プ４の外へ排出される。Water supplied from a pipe 3 branched from the discharge pipe 2 of the control rod drive pump 1 is supplied to the mechanical seal part 5 of the reactor recirculation pump 4, and the water that has passed there is used as purge water and discharged water. It is discharged out of the reactor recirculation pump 4 through a pipe 6.

を零にすることができる。In the prior art, waste water was discharged to a drain sump as containment vessel equipment drain, but in the present invention, the waste water is returned to the reactor system. In the embodiment shown in FIG. 1, the next discharge water passing through the discharge water pipe 6 is connected to the suction side pipe 7 of the control rod drive pump 1 to form a closed circuit, so that it is sent as a drain to the containment vessel equipment drain sump. The amount of water discharged can be reduced to zero.
本発明によれば、原子炉再循環ポンプのメカニカルシー
ル用−ジ水を原子炉系へ回収することによシ、次の効果
がある。According to the present invention, the following effects can be achieved by recovering water for the mechanical seal of the reactor recirculation pump into the reactor system.
（１）廃棄物処理設備へ流入するドレン量が軽減できる
。これによ勺、廃棄物処理設備容量のコスト低減が計れ
る。(1) The amount of drain flowing into waste treatment equipment can be reduced. This will help reduce the cost of waste treatment equipment capacity.
（２）処理設備における処理水の量が減少するため、余
剰水として、発電所外へ放出する水の量を低減できる。(2) Since the amount of treated water in the treatment equipment is reduced, the amount of water discharged outside the power plant as surplus water can be reduced.
（３）格納容器機器ドレンサンプへ、通常時、流入する
ドレン量が、非常に少なくなシ、機器の異常リークが発
生した場合の、ドレンサンプにおける、機器漏えい検出
が容易にできる。(3) Since the amount of condensate that normally flows into the containment vessel equipment drain sump is very small, equipment leakage in the drain sump can be easily detected in the event of abnormal equipment leakage.
