问题描述：
句子：Emergency procedures,and the mechanisms to ensure that they are carried out,have been established at national,provincial and company level,but Tian said coordination between the nuclear sector and social sector could be improved.请问这句话中的nuclear sector和social sector分别表示什么?
答
应急程序,和保证其开展的机制,已经在国家层面,省级层面和公司层面建立了.但是Tian认为核心部门和社会部门之间的协助还应提高.
所以核心部门是指代*,省级的（执行）应急程序（的部门）,社会部门指公司的,但是如果不局限于这句话的话应该还有一些别的社会部门的.
