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.
