1.   Engineers on Friday were analyzing a problem in one of two critical coolant loops for the payload bay doors.

2.   Antifreeze fumes continue to leak from coolant loops.

3.   Linenger said the crew has been able to depressurize the coolant loops to minimize the amount of escaping vapor.

4.   The flow of Freon in one of two coolant loops dropped drastically and even dipped a little below the safety limit.

5.   The problem in one of two coolant loops was noticed after Columbia reached orbit following its launch Friday.

6.   The South is satisfied because the statement specified reactors with two coolant loops, a design that South Korea has adapted from U.S. technology.

7.   They determined the radiators were still dispelling heat from various shuttle systems, and the coolant loop for the right door was working fine.

8.   No other reactors of exactly that type have the two coolant loops.
