After a lengthy interview with the facility's security officer, he was accepted for training. He signed a contract forbidding disclosure of sensitive security materials and had to promise not to visit any Arab or Communist countries for five years after his employment at the facility ended. He passed health checks, after which his training began. He was put through an intensive training course in physics, chemistry, mathematics, first aid, fire drill, and English. He did sufficiently well to be accepted and was employed as a nuclear plant technician and shift manager in February 1977. Vanunu earned a high salary by Israeli standards, and lived well. His work record was so good he qualified for a car and telephone allowance, though he had no interest in either and simply had his brother Meir's car registered in his name and had the telephone installed at his parents’ house.
