WebbIt also allows the reactor to be more compact. The PWR uses enriched uranium fuel with a slightly higher enrichment level than in a BWR. This is responsible for a higher power density within the reactor core. As with the BWR, the fuel is introduced into the core in the form of uranium oxide pellets. A typical PWR will contain 100 tonnes of uranium.
