NOTES:
1. Fire protection to be applied for whole process system up to isolation valve
2. Vertical height h1 of overfilling line is sized to create overflow at correct level, when
System is operating & differential pressure between PST and QEN head space of 5 kpa.
3. Igniters; BIG-2001 is sparking type, BIG-2101 is glow plug type.
4. Fire resistant thermal insulation with vapour barrier to avoid condensation at cold
outer tank walls and risk of water accumulation in the bund (BA-0001)
5. Bellow sealed gate valves are used on pipelines potentially exposed to tritium.
6. This piping is classified as Non-ESPN.
