The spectrometric complex STPK-01 for maintenance of the discrete – continuous operative control of specific activity of iodine radio-nuclides (131J-135J) in a wide range of values of the coolant in the basic (first) circuit of the nuclear reactor VVER-1000
|
PURPOSE
The spectrometric complex STPK-01 is intended for maintenance of the discrete - continuous operative control of specific activity of iodine radio-nuclides (131J-135J) in a wide range of values of the coolant in the basic (first) circuit of the nuclear reactor VVER-1000, and also periodic control of specific activity of a number of reference radio-nuclides important for an estimation of a technological condition of the coolant in the first circuit by means of gamma-spectrometry of high resolution..
