13.	We propose the following interlocks / trips in the system. 
a)	FFE:
&#61548;	Steam is to be cut if cooling water / chilled water supply fails. Hence, the PCV in the steam line should be PCV cum trip valve. 
&#61548;	The feed will be cut automatically after steam is cut based on level control in the FFE receiver. 
b)	ATFE:
&#61548;	The steam supply and then feed is to be isolated if chilled brine supply fails. 
&#61548;	Feed is to be isolated if steam supply fails. 
&#61548;	ATFE motor should on only if FCV in the feed line and PCV in the steam line are in open condition.
