Embodiment Construction

[0021] Such as figure 1 As shown, the present invention includes a carbon steel pipe 1 fixed with an upper steel plate 2 and a lower steel plate 3 and welded at the bottom, and a stainless steel liner pipe 4 welded at the bottom is placed in the carbon steel pipe 1 as the storage well wall, and the liner pipe 4. It is filled with benzyl silicone oil as a storage medium. Leakage must be checked before use to prevent leakage of the storage medium. The storage grid 5 is placed in the liner pipe 4 and immersed in the preservation medium. In order to increase the space utilization rate of the storage well, the storage grid 5 has five layers; the storage grid 5 is welded with a tray 6, and the tray 6 Place sample box 9 on it; also weld a cylindrical stainless steel shielding block 13 on the top of storage grid 5, be welded with storage well cover 14 on the top of shielding block 13, be welded with suspension ring 15 on the well cover 14.

Abstract

The invention discloses a storage device of irradiation supervision test samples of reactor pressure vessel material. The device adopts a well-typed design and a storage well takes underground type, thus occupying no space of a thermal ventricular; a sample storage framework adopts a multi-level structure and makes full use of the space of the storage well, thus the number of the samples for storing is greatly increased and the cost is low. By adopting the storage device of the invention, the storage effect of the irradiation supervision test samples of reactor pressure vessel material can be easy to check and an excellent shielding is conducted on the irradiation of the specimen at the same time.

Description

technical field [0001] The invention relates to a test sample storage device, in particular to a reactor pressure vessel material irradiation supervision sample well storage device. Background technique [0002] The reactor pressure vessel (RPV) is a large non-replaceable component in the reactor, and its life determines the life of the entire reactor. In order to ensure the safe operation of the reactor, it is necessary to monitor the actual degree of deterioration of the mechanical properties of the RPV material due to neutron irradiation, verify the accuracy of design calculations and predictions, and accurately evaluate the safety of the reactor pressure vessel. and provide a basis for life management. Since the irradiation space in the reactor is very limited and the number of irradiated samples is very small, it is required to store the broken samples after the RPV material irradiation supervision test and the samples not tested (such as bending samples) for a long ti...
