KAREN GOTT SWEDISH NUCLEAR POWER INSPECTORATE

Dr. Gott studied metallurgy and materials science at Imperial College, London.

During the more than 20 years she has worked in Studsvik Dr. Gott studied many aspects of the environmental effects on structural materials in nuclear power plants, both through contract research projects and failure analysis. She has held a number of different types of position whilst at Studsvik including project manager, marketing manager and manger of the reactor chemistry group. She was also on periodic loan to a US subsidiary in Richland, WA, to help them establish laboratory support for their decontamination services.

The main areas of her research activities were

• Creep crack formation in stainless steels (mechanical testing, electron and light optical metallography)

• Fracture mechanics (corrosion fatigue, residual stress measurement, non-destructive testing)

• Reactor chemistry (PWR and BWR chemistry, activity build-up including field measurements, decontamination)

• Reactor materials (surveillance testing, failure analysis, metallography of Inconel 182)

In her current position at the Swedish Nuclear Power Inspectorate she has continued to work in the field of environmental degradation of nuclear power plant structural materials. The work covers both the regulatory and the research aspects. On the regulatory side she is involved in the development of regulations, inspection and safety evaluations that form the basis for decisions based on Swedish law and regulations. One of her responsibilities includes the management of the materials and chemistry research area for the Inspectorate. In addition she has built a database covering operationally induced failures and damage to mechanical components in the Swedish nuclear fleet and is responsible for its maintenance and the associated analysis of failure cases. In 2003 she was on a six month job rotation to the Materials Engineering Branch of the NRC’s Office of Nuclear Reactor Regulation working amongst other things on PWSCC problems.

She is a member of the international conference committee which arranges the regular water chemistry conferences in the nuclear field, and has also acted on the international committee for the Fontevraud conference in France. She served as chairperson of the steering committees of two large international projects concerning irradiation assisted SCC and the establishment of a pipe failure database.
