Fukushima: Hydrogen Detonation & Destructive Missiles

Click on the following and then click on download and you will have the report by the Institute of Nuclear Power Operations (INPO).

After you download the INPO report, you may do a search on "missile" or "missiles" but you need not do that because you will have zero finds. However, next do a search on "debris" and you will have 35 hits. The hits include debris from the tsunami and also debris from the hydrogen detonations.

A search on "explosion" yields 51 hits, a search on "detonation" yields 0 hits.

A search on "hydrogen explosion" yields 8 hits.

The search on "debris" yields the following paragraph on page 13 of 104:

At 1536, an explosion occurred in the Unit 1 reactor building. This explosion was most likely caused by the buildup of hydrogen that had been generated in the Unit 1 reactor core and leaked into the reactor building. The explosion injured five workers, and debris from the explosion struck and damaged the cables and mobile generator that had been installed to provide power to the standby liquid control pumps. The debris also damaged the hoses that had been staged to inject seawater into Unit 1 and Unit 2. Fieldwork was suspended as workers were evacuated to the Emergency Response Center for accountability. Some of the debris was also highly contaminated, resulting in elevated dose rates and contamination levels around the site. As a result, workers were now required to wear additional protective clothing, and stay times in the field were limited. The explosion significantly altered the response to the event and contributed to complications in stabilizing the units.

Note that "... debris from the explosion struck and damaged ..." . It would be more precise to report that missiles from the hydrogen detonation struck and disabled robust equipment including the cables and a mobile generator that had been installed to provide power to the standby liquid control pumps.

A search on "hydrogen explosion" yields the following paragraph on page 36 0f 104:

A large hydrogen explosion occurred in the Unit 3 reactor building at 1101 on March 14. The explosion destroyed the secondary containment and injured 11 workers. The large amount of flying debris from the explosion damaged multiple portable generators and the temporary power supply cables. Damage to the fire engines and hoses from the debris resulted in a loss of seawater injection. Debris on the ground near the unit was extremely radioactive, preventing further use of the main condenser backwash valve pit as a source of water. With the exception of the control room operators, all work stopped and workers evacuated to the Emergency Response Center for accountability.

Again, it would be precise to substitute "hydrogen detonation" for "hydrogen explosion" and "energetic missiles from the hydrogen detonation" for "flying debris from the explosion." Energetic missiles will disable robust equipment including multiple portable generators and fire engines and hoses, flying debris may not.
