    Abstract

    This paper aims to introduce the application areas of the multifunctional high precision pneumatic loading system (HIPS), based on VTT developed and patented technology. The HIPS has been utilized in a number of different challenging environments, among others laboratory simulated nuclear power plant water environments such as the BWR, PWR and SCW, high temperature gas environment and actual nuclear reactor inpile testing. The test palette is also large, i.e. tensile testing, stress corrosion cracking, fatigue, creep fatigue, radiation impact on tensile and fatigue, and many variants with combined environmental impact. The HIPS has also successfully been used as mover system in a version of the contact electrode resistance measurement. The wide spectrum of tests enabled by the flexible concept is shortly described together with some test results from the different types of tests. The technological development path from single bellows tensile loading devices towards the more demanding double bellows fatigue and combined tension/compression/internal pressure system is described.
