IEEE Begins Work on Standard to Recommend Practices for Investigating Events at Nuclear Facilities - IEEE P1707
March 17, 2008 // Published as a news service by IHS
The standard will provide common terminology and recommended practices for initiating and conducting event investigations, analyzing data, producing results and identifying corrective actions associated with facility personnel, processes, equipment and systems at nuclear facilities.
The nuclear industry does not employ a common practice or approach to event investigations, which results in widely experienced terminology problems, according to the IEEE.
The IEEE also began work on revisions to several earlier power-related standards.
IEEE P622 - Recommended Practice for the Design and Installation of Electric Heat Tracing Systems for Nuclear Power Generating Systems updates the 1994 standard to reflect the state of technology in the nuclear industry.
Also being updated to reflect current technologies and specifications are IEEE P18 - Standard for Shunt Power Capacitors and IEEE PC57.19.03 - Standard Requirements, Terminology and Test Code for Bushings for DC Applications Rated 110 kV BIL and Above.
The IEEE also approved a revision to IEEE standard C57.93 - Guide for Installation and Maintenance of Liquid-Immersed Power Transformers.
The recommendations presented in this guide apply to the shipping, handling, inspection, installation and maintenance of liquid-immersed power transformers rated 501 kilovolt-ampere (kVA) and above with secondary voltages of 1000 volts and above.
This guide covers the entire range of power transformers including extra high voltage (EHV) transformers with distinctions as required for various sizes, voltage ratings and liquid insulation types.
The IEEE also reaffirmed three power-related standards:
- IEEE 1553 - IEEE Standard for Voltage Endurance Testing of Form-Wound Coils and Bars for Hydrogenerators.
- IEEE 295 - IEEE Standard for Electronics Power Transformers.
- IEEE 436 - IEEE Guide for Making Corona (Partial Discharge) Measurements on Electronics Transformers.
