あれから9年...

2003年8月14日の北米大停電から9年の時が流れた。テレメトリの不正値(12:15)、FirstEnergyの発電所ダウン(13:31)、Chamberlin-Harding送電線ダウン(15:05)あたりで始まり、16;05〜16:13で一気に影響が拡大して、カナダ1000万人、米国2400万人が影響を受けるに至った。

目立つのはこういった風景である。死者はわりと少なく、11名とされている。

• オンタリオ州では、交通事故で2名が死亡、火災で1名が死亡しているが、大停電のみが原因なのか不確定。
  
• コネチカット州で死者1名。
  
• ニューヨーク市では、一酸化炭素により2名、火災で2名、屋根から落下1名、17階まで階段で上がった後に心臓発作で1名が死亡。
  
• ミシガン州では、自家発電による一酸化炭素で1名、ロウソクによる火災で1名が死亡。

この背後で、サイレントに起きていたのはNYCAの外部電源喪失。

All of the nuclear units in the NYCA tripped off line during the initial event on or about 16:11. One unit continued to receive off-site power from the local Transmission Owner. As identified in the NYISO Restoration Procedure, highest priority is given to providing off-site power to nuclear power plants during system restoration activities. The Transmission Owners are the primary contact for the nuclear plants in the NYCA. During this event, the TOs insured that the requirements identified by the nuclear plants were met. As a result, nuclear plants in the NYCA were back on line between 01:05 August 17, Sunday morning, with four additional units coming on line through August 18, 2003 at 06:05. One unit remained off-line until August 22, 2003.

Blackout August 14, 2003　Final Report (NYISO) (2005/02) ]

1個は外部電源が維持され、最優先で外部電源が回復され、何事もなくグリッドに復帰している。なお、停止中の原子炉については、報告書などで軽い扱いになっているが、崩壊熱がそこそこ残っていれば、同様に最優先で外部電源回復させているはず。
