6.0 – FUKUSHIMA LESSONS LEARNED SUMMARY
This section summarizes the review of the implications of the Fukushima event for the
proposed Barakah site and facility. The FANR review of the Fukushima event will continue
during the construction period including requests for information from ENEC.
6.1 Overview of the Fukushima Event and Subsequent
International Analyses
One of the largest earthquakes in recorded history occurred on the east coast of Japan on
11 March 2011.
The nuclear power plants at the Fukushima Daiichi, Fukushima Daini, Higashidori,
Onagawa, and Tokai Daini nuclear power stations were affected, and emergency systems
were activated. All of these power plants successfully shut down immediately after the
earthquake. However, the tsunami generated by the earthquake then struck the east coast
of Japan.
Fukushima Daiichi Units 1 through 4 were significantly damaged by the tsunami and by the
subsequent accident sequences involving hydrogen evolution from overheated reactor fuel.
The subsequent accident sequences resulted in damage to the reactor cores and significant
release of radioactive materials beyond the site boundary.
6.2 FANR Regulations Applicable to the Fukushima
Review and Initial FANR Actions
FANR-REG-06, Article 6 requires any applicant for a licence to construct a nuclear facility to
provide “a description of how recent lessons learned and experience from other similar
facilities, scientific and technical developments, as well as the results of any relevant
research on protection and safety have been applied to resolve potential safety issues.”
Pursuant to this Article, FANR issued a letter on 30 March 2011, to ENEC requesting a plan
to evaluate and apply any applicable lessons from the event. Subsequently, FANR issued a
letter [Letter No FANR/DDGO/ENEC/COR/00081/2011] to ENEC 4 July 2011, providing
guidance to ENEC on the requested assessment of how recent experience at Fukushima
and lessons learned so far may be applied to address any potential safety issues at the
proposed Barakah Nuclear Power Plants. FANR requested:
1. An evaluation of the response of Barakah Units 1 and 2 and the Barakah site when
facing a set of extreme situations.
2. A verification of the preventive and mitigation measures selected in accordance with the
defence and depth approach: initiating events, consequential loss of safety functions,
severe accident management
ENEC submitted a report entitled “Safety Assessment Report for Braka Nuclear Power
Plants (Lessons Learned from Fukushima Accident),” through [Letter No. ENA/FANR/11/
0356L/LNP] on 30 December 2011, describing proposed design and mitigation measures to
improve the robustness of the Barakah facility against extreme events. ENEC also provided
a subsequent supplement on 30 January 2012, describing the relation of the proposed
