In 2000, Libya accelerated its efforts, still headed by Tinner. Libya received many documents on the design and operation of centrifuges, but the program suffered many setbacks in evaluating these designs as they were too difficult to interpret and bring into operation. Libya ultimately told IAEA investigators that it had no national personnel competent to evaluate these designs at that time, and due to its extreme difficulty, Libya would have had to ask the supplier for help if it had decided to pursue a nuclear weapon.
