Abstract

An apparatus for treating radioactive liquid wastes with solid and a control method thereof are provided to filter out a radioactive material included in the radioactive liquid wastes by using a liquid waste filter. A first liquid waste collecting tank(11) and a second liquid waste collecting tank(12) collect radioactive liquid wastes with solid. A centrifugal separator(20) separates the radioactive liquid wastes with solid supplied selectively from the first and second liquid waste collecting tanks into the liquid and the solid and discharges the separated wastes. First and second liquid waste filters(30,31) filter the radioactive material included in the radioactive liquid wastes supplied from the liquid outlet(21). If a radioactive level of the collected filtered liquid waste is below a predetermined level, a liquid waste collecting tank(40) discharges the liquid waste to the outside through an overflow(43). First and second radioactive solid waste storage tanks(50,51) collect and store the radioactive solid waste supplied selectively from a solid outlet(22). If a radioactive level of the stored solid waste is below the predetermined level, the first and second radioactive solid waste storage tanks discharge the solid waste through outlets(50a,51a).

Description

A treatment equipment of radioactive liquid wastes included solid and control method therefore}

본 발명은 고형물이 포함된 방사성액체폐기물의 처리설비 및 그 제어방법에 관한 것으로, 더욱 상세하게는 병원 등에서 인체의 진단 및 치료를 목적으로 방사성동위원소를 사용하여 발생되는 고형물이 포함된 방사성액체폐기물이나, 그 외 원자력발전소 및 일반산업체에서 입자가 작은 고형물들이 함께 상존하는 방사성액체폐기물을 신속하게 확실하게 처리하면서도 그 처리설비의 설치비용이 상대적으로 매우 저렴하면서도 작은 공간에서도 설치할 수 있는 구조를 갖도록 한 고형물이 포함된 방사성액체폐기물의 처리설비 및 그 제어방법에 관한 것이다.The present invention relates to a treatment facility for radioactive liquid waste containing solids and a control method thereof, and more particularly, to a radioactive liquid waste containing solids generated using radioisotopes for the purpose of diagnosis and treatment of a human body in a hospital or the like. In addition, other nuclear power plants and general industrial companies are required to have a structure that can rapidly and reliably treat radioactive liquid wastes where small particles of solids coexist, while installing the processing equipment at a relatively low cost and installing in a small space. The present invention relates to a facility for treating radioactive liquid waste containing solids and a control method thereof.

일반적으로, 병원 등에서 인체의 진단 및 치료를 목적으로 방사성동위원소를 사용하여 발생되는 고형물이 포함된 방사성액체폐기물이나, 그 외 원자력발전소 및 일반산업체에서 입자가 작은 고형물들이 함께 상존하는 방사성액체폐기물은 입자가 작은 고형물이 많기 때문에 각종 방사성 물질을 여과하는 여과장치의 필터들과 반응을 일으키기 전에 여과장치 내에 차압이 걸리게 되어 방사성 물질의 여과가 불가 능하다.In general, a radioactive liquid waste containing solids generated by using radioisotopes for the diagnosis and treatment of the human body in a hospital or the like, or other radioactive liquid wastes containing small particles of solids in nuclear power plants and general industries Due to the large number of small solids, it is impossible to filter the radioactive material because a differential pressure is applied in the filtering device before the reaction with the filters of the filtering device for filtering various radioactive materials.

따라서, 종래에는 이러한 고형물이 포함된 방사성액체폐기물을 액체폐기물수집탱크 내로 수집한 후 방사능농도가 원자력법에서 제시하는 법적 기준치 이하가 될 때까지 액체폐기물탱크 내에 방사성액체폐기물을 저장하고, 법적 기준치 이하가 되었을 때 액체폐기물을 배출시키는 방식으로 고형물이 포함된 방사성액체폐기물을 처리하고 있다.Therefore, conventionally, after collecting the radioactive liquid waste containing such solids into the liquid waste collection tank, the radioactive liquid waste is stored in the liquid waste tank until the radioactivity concentration is lower than the legal standard set forth in the Atomic Energy Act, and below the legal standard. When this is done, the radioactive liquid waste containing solids is treated in such a way as to discharge liquid waste.

즉, 일 예로서, 갑상선치료를 위해 방사성동위원소 I-131(물리적 반감기는 약 8일)을 사용한 경우 2박3일 동안 환자의 소변, 대변 및 세안 등으로 인해 발생되는 오수를 모두 방사성액체폐기물수집탱크 내로 수집한다. 이렇게 수집된 방사성액체폐기물에는 대변 등으로 인해 입자가 작은 고형물들이 대량 포함되어 있어 여과 및 이온반응에 의한 방사성 물질의 제거가 불가능함으로 방사성액체폐기물수집탱크의 수위가 예정치에 도달하면 더 이상의 방사성액체폐기물의 유입을 막고, 저장된 방사성액체폐기물의 방사능 농도가 예정치 이하가 될 때까지 차폐된 상태로 저장한 후 방사능 농도가 예정치 이하에 도달하였을 때 배출시켜 방사성액체폐기물수집탱크를 비우는 방식을 고형물이 포함된 방사성액체폐기물을 처리한다.That is, as an example, when radioisotope I-131 (physical half-life is about 8 days) is used for thyroid treatment, all of the sewage generated by the patient's urine, faeces, and face washing for 2 days and 3 days are radioactive liquid waste. Collect into the collection tank. The collected radioactive liquid waste contains a large amount of solid particles with small particles due to feces, etc., so that it is impossible to remove the radioactive material by filtration and ionic reactions. When the level of the radioactive liquid waste collection tank reaches a predetermined level, the radioactive liquid is no longer radioactive liquid. To prevent the inflow of waste, store the radioactive liquid waste in a shielded state until the radioactive concentration is below a predetermined value, and discharge the radioactive liquid waste collection tank by emptying the radioactive liquid when the radioactive concentration reaches the predetermined value. Treat these contained radioactive liquid wastes.

그러나, 이러한 종래의 고형물이 포함된 방사성액체폐기물의 처리방법은 방사성액체폐기물수집탱크의 용량 및 대수(臺數)가 충분하기 않을 경우 의료 및 산업적으로 사용되고 있는 방사성동위원소들의 물리적 반감기가 최소 수일(I-131의 경우 약 8일)이기 때문에 쉽게 방사능 농도 수치가 줄어들지 않아 원하는 시기에 저장보관된 방사성액체폐기물을 배출하기 어려워 진단 및 치료를 요하는 환자의 수를 제한해야 하기 때문에 환자의 건강에 중대한 악영향을 미칠 수 있음은 물론 방사성액체폐기물수집탱크의 추가설치 또는 신설시 충분한 용량 및 대수(臺數)를 갖도록 설치하여야 하고 넓은 설치장소를 필요로 하기 때문에 설치비용이 매우 높을 뿐만 아니라 원자력발전소 및 일반산업체의 경우에도 설비비용이 과다함은 물론 방사성액체폐기물의 처리기간이 길어 작업 생산성이 크게 저하된다는 문제점이 있었다.However, such a conventional method for treating radioactive liquid waste containing solids has a physical half-life of radioactive isotopes that are used in medical and industrial applications for a minimum of several days if the capacity and number of radioactive liquid waste collection tanks are not sufficient. 8 days for I-131), the level of radioactivity is not easily reduced, and it is difficult to discharge the radioactive liquid waste stored at the desired time, which limits the number of patients requiring diagnosis and treatment. Not only can it adversely affect the installation, but also the installation and installation of a radioactive liquid waste collection tank should have sufficient capacity and number, and the installation space is very high. Even in the case of industrial enterprises, the cost of equipment is excessive and the disposal of There was a problem in that period, the productivity decreases significantly longer.
