According to these allegations, at the time of the accident the reactor was being operated with many key safety systems turned off, most notably the Emergency Core Cooling System (ECCS), LAR (Local Automatic control system), and AZ (emergency power reduction system).
Segundo estas alegacións, no momento do accidente o reactor estaba sendo operado con moitos sistemas de seguridade claves apagados, sobre todo o Sistema de Refrixeración de Emerxencia do Núcleo, o sistema de control automático local, e o sistema de redución de potencia de emerxencia.
