    Abstract
    Nuclear weapons can be constructed with either highly enriched uranium or plutonium. The uranium weapons are less technically demanding and do not require testing. Developing states pursuing a secret weapons programme, and terrorist organisations seeking nuclear capabilities will most likely choose a uranium weapon. The amount of uranium needed to construct one weapon is dependent on the enrichment level of the material. We show that if the enrichment exceeds 80 % in uranium-235, even a crude design could work with less than 80 kg.
     
    Kjernefysiske våpen kan lages med enten høyanriket uran eller plutonium. Uranvåpnene er mindre teknisk krevende og det er mindre behov for prøvesprengning. Uran vil sannsynligvis være førstevalget til en terrororganisasjon eller en mindre utviklet stat som starter et hemmelig program. Mengden uran som behøves for å lage ett våpen avhenger av anrikningsgraden til materialet. Vi ser at hvis andelen uran-235 overstiger 80 %, kan selv et primitivt våpen lages med mindre enn 80 kg.
