WWER-440 V-213型反应堆压力容器配备了用于预测反应堆压力容器材料脆化的监督试样。这些样品位于堆芯附近，导致加速辐照。经过四年的运作，每个单元只剩下一台曝光过度的电视机。为了获得用于寿命计算和寿命管理的更广泛的数据库，已经详细说明并实施了一种新的、更广泛的监视探针。由于档案材料的有限性，重建夏比V试样和小尺寸的光滑和缺口拉伸棒中使用的程序。为了发展这一监督扩展，进行了广泛的实验室研究，使用重建的夏比和次尺寸拉伸试样。本文还对小试样K1 a的测定方法进行了研究.
The WWER-440 V-213 type RPVs are equipped with the surveillance specimens used to predict the embrittlement of the RPV material. These specimens are located near the core, resulting in accelerated irradiation. After four years of operation only one overexposed set remains in each unit. To obtain a more extensive database for life time calculation and life time management, a new, more extended surveillance pron has been elaborated and implemented. Due to the limited availability of archive materials reconstructed Charpy V specimens and small size smooth and notched tensile bars were used in the program. To develop this surveillance extension, an extensive laboratory study on use of reconstructed Charpy and subsize tensile specimens was performed. Methods for K 1 a measurements on small size specimens were also studied.
