An error occured in the Reaktor Journal Volume 17 No. 3 months published in September 2017 and Volume 17 No. 4 published in December 2017.
It was written Acredited: SK No .: 60 / E / KPT / 2017 which supposed to be Acredited: SK No .: 60 / E / KPT / 2016.
Thus we make this letter as an attachment to articles published in the Reactor Journal 2017 Volume 17 No. 3 and No. 4 to be used as intended.
