Triggering an alarm of low steam pressure in the steam separators before the explosion
Time: Saturday Apr 26, 1986 at 01:19:00 AM
Place: Chernobyl, Ukraine, U.S.S.R
Details: The flow exceeded the allowed limit at 01:19, triggering an alarm of low steam pressure in the steam separators. At the same time, the extra water flow lowered the overall core temperature and reduced the existing steam voids in the core and the steam separators. Since water absorbs neutrons better than steam, the neutron flux decreased and reduced the reactor power. The crew responded by turning off two of the circulation pumps to reduce feedwater flow in an effort to increase steam pressure, and by removing more manual control rods to maintain power.

Best-effort ordering. Some events may appear out of order since many are only known to the year, but they are usually around the same period.
