SHANGHAI, Feb 4 (Reuters) - China shares rose for a second day on Wednesday, pushed up by energy stocks after Chinese nuclear power firms announced plans to merge in a bid to boost offshore clout.
Shanghai Electric Power Corp Ltd said its parent company, China Power Investment Corp, had received approval to start work on a merger with State Nuclear Power Technology Corp (SNPTC).
