Olkiluoto 3 is an EPR. Production of weapons plutonium requires a short soak time of only a few weeks. A pressurized reactor isn't suited to such short fuel burn, since it has to be stopped and depressurized to swap fuel bundles. There's no capability to continuously feed and remove fuel pellets in FIFO order (like the Hanford reactors), or remove individual bundles while running (like an RBMK or CANDU).
