F. R. Farmer

F. R. Farmer

F. Reg Farmer OBE, FRS, (1914-2001) was a nuclear regulator (working for the United Kingdom Atomic Energy Authority's Safety and Reliability Directorate, SRD) and later an academic at Imperial College London.

Accomplishments

*He considered the public acceptability of risk, (eg from nuclear reactors), arguing that a whole spectrum of events needs to be considered - not just the Maximum Credible Accident, but also those of less consequence but which were much more probable.

*He used examples such as hill walking to define a spectrum of risks which people found acceptable.

*He embodied this in a variation of (Acceptable Risk Frequency/Event Probability) with (Consequence), which is usually called the Farmer Curve.

*Farmer postulated a near-inverse variation as acceptable - thus events which have twice the consequence must be approximately half as frequent, or less. The Farmer Curve is usually plotted as a straight line in log-log co-ordinates.
