A small mud pit with a capacity of 10 to 15 bbl, usually with 1 bbl divisions, used exclusively to ascertain the amount of mud necessary to keep the well bore full with the exact amount of mud that is displaced by drill pipe. When the bit comes out of the hole, a volume of mud equal to that which the drill pipe occupied while in the hole must be pumped into the hole to replace the pipe. When the bit goes back in the hole, the drill pipe displaces a certain amount of mud, and a trip tank again can be used to keep track of this volume.  2, record 1, English, - trip%20tank

This was a fast-acting liquid poison injection system comprising a number of small tanks containing gadolinium nitrate solution which were connected to perforated Zircaloy in-core injection tubes. The top of each poison tank was connected to high pressure helium storage tanks via an array of valves which were opened on a trip signal, thereby pressurizing the poison solution and causing it to flow rapidly into the perforated in-core tubes and, hence, into the bulk moderator.  2, record 2, English, - poison%20tank
