This paper describes the instrumentation of a full-scale test, known as the Multi-Purpose Test, of the KBS-3H spent nuclear fuel design alternative carried out in the Äspö Hard Rock Laboratory (Sweden). This test is part of the Large Underground Concept Experiments EU project, where Posiva and Svensk Kärnbränslehantering are partners. The test consists of two aspects. The first is that of a ‘demo’ test whose aim is to check the manufacturing and installation process of the different components of the KBS-3H design. The second is the instrumentation and monitoring of the test system. The test is carried out under isothermal conditions and the scope was to measure component displacements, the hydration and swelling pressure of the bentonite material and the water pressure in host rock.

瑞典KBS-3H乏核燃料库替代品的全面测试

本文介绍了在ÄspöHard Rock实验室（瑞典）进行的KBS-3H乏核燃料设计替代方案的全面测试（称为多功能测试）的仪器。此测试是欧盟大型地下概念实验项目的一部分，Posiva和SvenskKärnbränslehantering是合作伙伴。该测试包括两个方面。第一个是“演示”测试，目的是检查KBS-3H设计的不同组件的制造和安装过程。第二个是测试系统的检测和监视。该试验在等温条件下进行，其范围是测量组分位移，膨润土材料的水合作用和溶胀压力以及基质岩石中的水压。
