• 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
