Based on it, in 1992 the IAEA Nuclear Safety Advisory Group (INSAG) published an additional report, INSAG-7, which reviewed "that part of the INSAG-1 report in which primary attention is given to the reasons for the accident," and was included the USSR State Commission report as Appendix I. In this INSAG report, most of the earlier accusations against staff for breach of regulations were acknowledged to be either erroneous, based on incorrect information obtained in August 1986, or less relevant.
Baseado nisto, en 1992 o Grupo Asesor de Seguridade Nuclear do OIEA publicou un informe adicional, INSAG-7, que revisaba "aquela parte do informe INSAG-1 na cal a atención primaria dáse ás causas do accidente", e incluíu o informe da Comisión Estatal soviética como Apéndice I. Neste informe da INSAG, moitas das acusacións iniciais contra o persoal pola violación das regulacións recoñecéronse erróneas, baseadas en información obtida incorrecta en agosto de 1986, ou menos relevantes.
