APWR Progress Report

A new generation LWR “APWR” started as Japanese national project more than 20 years ago.

APWR has been standardized for worldwide market as US-APWR and EU-APWR.

Larger output and improved reliability based on best mix of proven technologies 1,700 MWe class power production

24 months fuel cycle with on-line maintenance

4 train safety system with advanced accumulator

Fully digital I&C and computerized MCR

24


US-APWR

DC application under reviewing by USNRC, planned to be

certified in 2011

COL applications for two sites under reviewing

EU-APWR

Design modifications will be finished this year considering

European safety requirements.

(SA, APC, etc.)

Preparing for EUR assessment.

Towards the Future

Earlier discussion with utility is important for mutual understanding and to achieve on schedule design, licensing and construction.

Pre-application discussion with licensing authority is quite effective to address important safety issues and to establish clear licensing procedure and schedule

Worldwide cooperation of industries and authorities is useful to establish international standards.
