摘要

In the authors' ongoing research [1], an Integrated En-terprise Risk Management (I-ERM) methodological frame-work is developed in order to promote the sustainability of the U.S. nuclear fleet by supporting plant decision-making with respect to improving safety, cost savings and avoidance of production loss, while satisfying short- and long-term regulatory requirements. The I-ERM framework focuses on two main interrelated outcomes of an organization: safety outcome and financial outcome. For the nuclear power op-erating organizations, the I-ERM framework measures safe-ty based on the systematic risk estimated from Probabilistic Risk Assessment (PRA), and measures financial outcomes based on profitability, or revenue minus cost (e.g., Opera-tions and Maintenance [O&M] costs). Compared to existing ERM approaches, the value of I-ERM is that more in-depth causalities for physical degradation (e.g., stress corrosion cracking) and social contributing factors (e.g., human and organizational factors), associated with O&M of the Nuclear Power Plants (NPPs), are explicitly incorporated into an integrated timely-synchronized assessment of safety risk (i.e.. Core Damage Frequency [CDF] and Large Early Re-lease Frequency [LERF]) and financial risk. The explicit incorporation of underlying causal mechanisms can help more realistically address the interrelationship and depend-ency between safety risk and financial risk induced by their shared physical and social contributing factors. In addition, the explicit incorporation of underlying causal factors al-lows for an in-depth importance measure analysis to identify the most critical safety and cost contributors, thus enhancing ERM by helping the decision makers generate more effec-tive and efficient O&M strategies for the prevention and mitigation of undesirable events.
