The test type of the seismic strength of electrical equipment is the shaking table test for Safe Shutdown (SSE) earthquake. The aim of the test is to demonstrate the seismic strength of electrical equipment according to YVL2.6 standard of Finnish Radiation Protection Centre (STUK). In the test program the adequacy of the excitation time history of the shaking table is secured with an appropriate coefficient in which case it is also possible to quantify the protection margins of the seismic strength. In the case when one dimensional shaking table is used the three dimensional strength of the equipment item is secured by augmenting the test excitation with appropriate coefficients. In case of need, the proper three dimensional testing is used for validating the results of one dimensional test. The detailed test program follows the criteria laid out in the IEC – 60980 [1] and IEC - 60780 [2] standards. The scope of the testing program is the six most important electrical equipment item types which are to be renewed in the scope of the renewal project. The basic data of an equipment item type to be tested is as follows: 1) the location inside the plant, 2) the description of the structure of the item; 3) connections to other equipment; 4) the functional criteria for accepted performance. The end result of the test for each equipment item is the testing report describing the detailed conduct of each test and the behavior of the test item during the test and conclusion concerning the seismic adequacy of the item.
