The [Nuclear Regulatory Commission lacks] [the tools and analysis techniques necessary to independently assess] the [next generation of nuclear power plants] due to their [limited experience] with [advanced nuclear reactors]. My research is on [new regulations and analysis tools] that can help [ensure] the [safety] of these designs.
Ladder can be used to determine an organization's level of maturity A 'health warning' on the Maturity Model Useful for categorising an organization and monitoring progress but a very rough measure Organizations made up of different 'subcultures' – this is a fact that is often overlooked in the measurement of safety culture
Insight Corrosion issues in nuclear industry today. The world's fleet of nuclear power plants is, on average, more than 20 years old. Even though the design life of a nuclear power plant is typically 30 or 40 years, it is quite feasible that many nuclear power plants will be able to operate for longer than this.

Feb 22, 2002· The first generalpurpose electronic computer consumed 140,000 watts of power. After the invention of the transistor, power usage dropped dramatically and the computer industry lost interest in power requirements. Today power management is back in the spotlight for several reasons, and the operating system plays a role.
Apr 26, 2016· INSAG concluded that the need to create and maintain a 'safety culture' is a precondition for ensuring nuclear power plant safety. The concept of 'safety culture' relates to a very general concept of dedication and personal responsibility of all those involved in any safety related activity at .
