Condolences


Appreciations 4

�Rescue Teams from 16 countries and organizations,

�Aid from 130 countries and 33 organizations,

�Tremendous Purse and Donations from all over the world,


�Many PRAYERs through e-mail and phone calls.

>30,000 people have been rescued from debris & rubble,

Although many Japanese have been facing problems and some few are selfish, we feel OK and try to act less, gently and moderately.

Tsunami 5


When it started, it reached at highest within 6 minutes, andBigger ones attacked several times after hours.

- hundreds of thousand people away from home over night

What Happened?12

�Fukushima #1, #2 and Onagawawere attacked by Tsunami with more than 10 meters high in spite of the estimated maximum deserter case as 5 meters at Fukushima, and these two sites, Fukushima #1& #2, went into emergency level, while Onagawasite has been OK, since it was designed against 9.1 meters,

� We do not know yet how seriously the earthquake itself damaged


� We do not know yet how seriously the earthquake itself damaged the sites, but all nuclear reactors could be controlled down to non-active mode and they were under control by designed emergency process, but Tsunami at two sites after one hour later with more than 10 meters high destroyedmost of emergency electric generators and oil tanks for the emergency operations,

�Water cooling &circulation systemswere stoppeddue to the regular electricity cut and also by the damage of emergency generator systems,

What Happened? 13

�Then the water in cooling nuclear reactors to non-active mode was boiled up in the air-proof vessels, some of them were converted to Hydrogen, and hydrogen was thrown out and explored by unknown reasons,

�Explosionswhich broke walls and ceilings of the plant buildings were several times by which 15 brave workers were injured, and


were several times by which 15 brave workers were injured, and serious radioactive radiation has been measured in various places close to the site,

�Hard efforts have been put to stop increasing heat inside reactors and to reduce radiation by pouring water and recovering electricity to control systems.

� 10 days later, brave repairmen started to enter into the buildings,

What Happened? 14

� 3 repairmen were seriously injured by radiation and sent to hospital,

� 17 braves are over 100 mSv, and 88 habitants were medicated to take out the affect of radiation (as of 25th March),

� Radioactivity measurement of reactor buildings after 2 weeks revealed very serious results such as >1 Sv, 3Bq/cm3 (10E5 times over


revealed very serious results such as >1 Sv, 3Bq/cm3 (10E5 times over normal), which indicates serious nuclear fuel rod failure,

�Staying at home is still not dangerous beyond 20 km (extended to 30 km 10 days later) apart from two sites,

� Radiation, however, has been affecting some foods & water little by little ,

e.g. water for baby milk-powder, leaf-vegetable,

Current Problems related to Electric Energy 20

� Japan is divided into two regions, 50Hz and 60Hz, and operated by 9 regional dominant Electric Power Companies + minor private suppliers (5% in total)

� Power cut in Greater Tokyo operated by Tokyo EPC which owns Fukushima NP is very serious over all social sectors;

- shortage; 10MkW/h out of 41MkW/h required


- shortage; 10MkW/h out of 41MkW/h required

� Scheduled power cut has been operated as;- 5 groups depending on area fixed, - 3 hours cut in each group per day,- planed cut hour; 6am-9am, 9am-12am, is rotated

� Too simple method for real social activities=> much less consumption than planned

Findings toward Smart Electricity 21

� Much more precisefeeding/receiving control (cut or reduction) is essential based on sector by sector not by area by area for sharing limited resources;

- Stable power feeding to Enterprises and Public sectorseven in reduced mode,

- Fairnessover entire Homes when cut/reduction is requested, and


requested, and- Exceptions should be implemented.

� Visualization of usage at various sites should be realized,- individual entity, region, sector, and total- mid-term prospect, daily forecast & result record

� Remote control, various stoking and smart transportation of electricity will be very useful,

Findings toward Smart Society 22

� about Electrical Vehicle;Pro: - excellent for minimal sustainable energy

- movable & flexible energy - storage capability at less demand time, e.g. night- stabilizer for daily dynamics of demand- ad-hoc networking capability


Con: - too much power consumption by full timecharging

- useless in long time electricity cut

� Change our minds, actions and systems toward reduced and shared energy societybe a primary factor to Smart Society, and Technologybe essential for Smart Society.

23Reconsideration needed to the Current Plan

300 BUSD will be necessary for recovery.“Ground design toward SMART SOCIETY ”

Japan is heavily damaged by the earthquake and huge tunami

which cases enormous difficulties now,

Japan will re-shape it as a Smart Society
