Simulation leads to robust control of nuclear plant. (Nuclear Electric PLC migrates from mainframe computers to SPARC workstations)
July 1, 1994... Nuclear Electric is in the final stages of migrating its simulation software, data and algorithms from mainframes to parallel SPARC stations. In so doing, it is gradually handing over the responsibility for managing simulation and...

Gas detection. (gas detector innovations)
July 1, 1994... IS LEGISLATION THE NEW MOTHER OF INVENTION? LEIGH GREENHAM, OF CROWCON DETECTION INSTRUMENTS, LOOKS AT WHAT'S HAPPENING Designers and manufacturers of gas detection equipment are constantly being asked to produce instruments and systems which...

Tank gauging art or science? (monitoring levels of storage tanks)
July 1, 1994... THE NEED FOR ACCURACY AND THE SHEER RANGE OF PLANTS MAKE THANK GAUGING AS MUCH AN ART AS A SCIENCE Typical capacities of bulk storage tanks range from 1,000[m.sup.3] to more than 120,000[m.sup.3], and the value of the products stored can be...

Reflection-based level detection. (microwave liquid level sensors)
July 1, 1994... Non-contact techniques, such as ultrasonics and microwave reflection, enjoy many inherent advantages for measuring level. Measuring accuracies are not affected by changing product characteristics, such as conductivity, dielectric constant or...

Overfill protection - will the UK adopt similar standards to those in Germany for detecting levels of potential pollutants? (regulations concerning protection from overfilling of storage tanks with hazardous liquids)
July 1, 1994... No UK regulations yet cover the safe filling and protection from overfilling of industrial vessels containing hazardous liquids and pollutants. Fines for delinquent operators are frequently imposed after spillages, and widely reported, but what...
