The chernobyl accident updating of insag 1

The monitoring system recorded proper operation of the pumps right up to the sudden power surge.

Pumps powered by a generator that was running down could not in any way have suffered breakdown. The first to be switched off, though, were those very “running down” pumps (see , Annex I, Table I-I), then, powered from the back-up supply.

They should not have been there and they were taken as spurious because they could not be explained.

But in reality these were power surges caused by the emergency protection, which were not recorded by the SKFRE (power density physical monitoring system) automatic recorder because of the slow response time of the silver transducers used.

I pointed out the falsity of this assumption back in 1987, in a letter addressed to the Director General of the International Atomic Energy Agency.

At low reactor power, boiling begins beyond the core anyway, in the steam-water communication (SWC) line pipework, and the location of boiling moves down gradually as power rises (Figure 1).The reactor is operated only in boiling mode, and, according to the regulations, may be operated with minimal or even zero subcooling – see Regulations, Chapter 9.This condition is obligatory, since such operating conditions cannot be avoided in principle – they occur with any rise in power, when the pressure falls in the separators.By Anatoly Dyatlov [article published in NEI September 1995] May 1993).Seven years is long enough to study a lot of research and to formulate an opinion.
