One of the primary lessons learned from the accident at Fukushima Dai-ichi was the significance of the challenge presented by a loss of safety related systems following the occurrence of a beyond-design-basis external event. In the case of Fukushima Dai-ichi, the extended loss of alternating current power (ELAP) condition caused by the tsunami led to loss of core cooling and a significant challenge to containment. NRC and NEI made an approach for adding diverse and flexible mitigation strategies-or FLEX- ...

Survey of Palo Verde Nuclear Power Plant and Diablo Canyon Nuclear Power Plant

Now, 20% of the world’s nuclear power plants are operating beyond 40 years. By 2020, about 30% of the world’s nuclear fleet will be 40 years old. Long time operation (LTO) of existing plant is a key objective in many countries. We need to understand anticipate and mitigate the degradation in nuclear power plants. IAEA have made the guidelines about long time operation and opened PLIM conference once in 5years.In the United States, industry and NRC/DOE have started research program on the subsequent license ...
