Emergency power generators, mobile pumps, power cables, coolant hoses, diesel in portable tanks, boric acid to prohibit chain reaction in reactor, tools, protection equipment and measuring devices for radiation protection, fire fighting equipment



Consequence of Fukushima Daiichi accident



Swiss Recommendations – order according priority (1)

Beyond design basis accidents

- a. Design modifications to mitigate severe accidents

- b. Seismic trip systems, severe accident monitoring

- c. Control room operability in severe accident sequences (primary protections,

redundancy)

- d. Improved instrumentation, communication networks, etc.

- e. Improved emergency response plans including command and control, off-

site preparations and off-site support

- f. How far beyond?

- g. Datalinks to regulator

- h. Crisis centres




People” support

- c. Training, pre-job briefing

- d. Knowledge management, knowledge capture and retention, knowledge

presentation

- e. Emergency preparedness special trainings for emergencies and simulations

- i. Reduction of human errors

Cybersecurity

- a. Vulnerability of digital I&C systems in NPPs’ control and safety systems




Standards, requirements and regulations, safety classifications,

definitions

- a. Harmonization and reduction (first, in safety systems only)

- b. Assistance with standards interpretation

- c. Harmonization of definitions

Information management and sharing (medium)

- a. Develop an information sharing system

- b. Lessons learned from incident reporting systems databases

- d. Network of I&C experts

IAEA should take a lead in analysis of I&C operations during and after

Fukushima accident progressions and publish report




Wireless technology in normal operations and accident conditions
