Probe TP-14 mendeteksi lonjakan suhu dari 52 °C ke 58 °C dalam 8 jam kemudian tembus ambang kritis 60 °C pada 02:47. SOP memerlukan tindakan reshape + cooling compaction dalam 12 jam untuk mencegah self-combustion. Probe TP-14 detected a rise from 52 °C to 58 °C over 8 hours, then crossed the 60 °C critical threshold at 02:47. The SOP mandates reshape + cooling compaction within 12 hours to prevent self-combustion.

Prediksi Foxel 24 jam ke depan Foxel 24-hour forecast
Tanpa intervensi, model memproyeksikan TP-14 mencapai 68-72 °C dalam 24 jam dengan probabilitas ignition 14%. Cooling compaction + reshape + quarantine zona NE-2 akan turunkan suhu ke 48-52 °C dalam 36 jam (probabilitas 96%). Without intervention, the model projects TP-14 to reach 68-72 °C within 24 hours with a 14% ignition probability. Cooling compaction + reshape + quarantine of sector NE-2 will drop temperature to 48-52 °C within 36 hours (96% probability).
