Problems solved by technology

Thermal stress is a kind of shear stress. The direction of thermal stress is perpendicular to the base surface. Thermal stress may cause lateral relative displacement of the base and reduce the reliability of the support of the base to the internal components of the pile.

Abstract

The invention discloses a flange connection structure, which is used to connect a hanging basket and a base in a reactor. The flange connection structure includes an upper flange fixed on the hanging basket and an upper flange fixed on the hanging basket. The lower flange on the base, the flange connection structure also includes: a longitudinal stopper arranged between the upper flange and the lower flange, the longitudinal stopper is opposite to the upper flange And the lower flange is longitudinally limited; the transverse limiter is arranged between the upper flange and the lower flange, and the transverse limiter is used for the upper flange and the lower flange. Carry out lateral limit. By using the above-mentioned flange connection structure, the base not only effectively supports the hanging basket, but also can withstand the thermal stress caused by temperature changes, ensuring that the base will not undergo longitudinal displacement and lateral displacement, and improving the reliability of the base supporting the hanging basket.

Description

technical field [0001] The invention relates to reactor internal equipment, in particular to a flange connection structure. Background technique: [0002] In a deep-water pool-type low-temperature heating reactor, the core, control rod drive mechanism, reactor internals, base and other components together constitute the pool internals. The base is a part that supports the internal components of the pile, and the base is usually connected with the lower hanging basket in the internal components of the pile, so as to realize the supporting function of the base on the internal components of the pile. [0003] In the deep pool type low-temperature heating reactor, the base needs to bear the gravity of the reactor internals and other related components, and when refueling, the hanging basket on the reactor internals needs to be removed, and the reactor internals need to bear the longitudinal pull during the dismantling operation At the same time, considering the accident conditi...
