High-radioactivity waste receiving device

Abstract

The invention belongs to the technical field of high-radioactivity waste storage, and particularly relates to a high-radioactivity waste receiving device. The purpose of the invention is that when anabnormal situation occurs during cobalt isotope production, corresponding high-radioactivity waste can be safely placed in a waste receiving cylinder of a spent fuel pool receiving device, operators can be protected effectively, and the cobalt isotope can be normally produced. The device is characterized by comprising a long-handle tool A, a waste box, box clamping bottom plates, a waste receivingcylinder, lifting rings, a support, a long-handle tool B, a guide sleeve and a stud. The high-radioactivity waste receiving device provided by the invention is safe and reliable, is convenient to useand is high in stability, the economic benefit is high, operation risk is reduced, the risk that the workers receive accidental-dose irradiation is avoided, and safety of operators is ensured, so that requirements of cobalt isotope production in the service life period of a power station is met, and an advanced level of similar high-radioactivity waste storage equipment of same power stations athome and abroad is achieved.

Description

technical field [0001] The invention belongs to the technical field of high radioactive waste storage, and in particular relates to a high radioactive waste receiving device. Background technique [0002] Qinshan Nuclear Power's two heavy water reactor units can produce cobalt isotopes in addition to normal power generation. That is, when the unit is scheduled to shut down, cobalt 59 is loaded into the reactor. When the unit is scheduled to shut down in the next operating cycle, it will receive The cobalt 60 irradiated in one cycle is released from the pile. After the cobalt 60 is discharged from the pile, it is processed by underwater production equipment and then sent to the corresponding destination for sale. However, after underwater production, there is no problem in shipping out the finished product, but there are still Corresponding high-level radioactive waste cannot be transported out, such as cobalt rod lock nuts, rod bundle upper and lower fixing plates, etc. At t...

[0002] Qinshan Nuclear Power's two heavy water reactor units can produce cobalt isotopes in addition to normal power generation. That is, when the unit is scheduled to shut down, cobalt 59 is loaded into the reactor. When the unit is scheduled to shut down in the next operating cycle, it will receive The cobalt 60 irradiated in one cycle is released from the pile. After the cobalt 60 is discharged from the pile, it is processed by underwater production equipment and then sent to the corresponding destination for sale. However, after underwater production, there is no problem in shipping out the finished product, but there are still Corresponding high-level radioactive waste cannot be transported out, such as cobalt rod lock nuts, rod bundle upper and lower fixing plates, etc. At the same time, the lock nuts may be deformed after the reactor is irradiated, and cannot fall off the dismantling tool freely. In view of the above factors exist, and it is necessary to develop an underwater high-level radioactive waste receiving device to meet the normal production of cobalt-60 during the entire lifetime of the power station.
