Deep Space: The new frontier of radiation controls
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

The overall control architecture serving the European Tritium Handling Experimental Laboratory (ETHEL) consists of two types of apparatus:1) Programmable Logic Controllers (PLCs), Personal Computers (PCs), networks which constitute the so-called Distributed Digital Control System (DDCS); 2) Fail-safe hard-wiring which operates independently of the DDCS. This paper deals with the first type of apparatus; its hardware and software are described. The computerized system, defined by a four-level hierarchical and modular architecture, is a large distributed Real-time Control System. The operation is mainly centralised in the Control Room through a fully programmable man-machine interface (graphic displays, trends, etc.).
