• Awalnya diduga penyebab

ledakan dari F-3 berasal

dari terbentuknya gas H2 di

fuel pool, sehingga

penyiraman dengan

helicopter perlu dilakukan

• Karena radioaktivitas sangat

tinggi dan adanya puing-

puing, maka mobil

pemadam tidak dapat

mendekat

Ledakan gas H2 pada F-4 yang sedang dalam kondisi

maintenance diduga berasal dari terbentuknya gas H2

pada fuel pool yang tidak tertutup air
