Study on Utilization of an Artesian Well as a Source of Water Supply at Raw Water Backup System (GBA01)

Raw water supply system (GBA01) is a unit of ponds used as a provider of raw water for secondary cooling system and free mineral water production systems. Source of raw water pond has been supplied from PAM Puspiptek with water conductivity between 126-310 μS / cm and a pH of 6 to 8, and this condition is maintained because there is no other source that is used to supply water to the reactor cooling water supply. This conductivity is always unstable, if during the dry season the conductivity is low trend, but in the rainy season the conductivity will be increase because the water contains a lot of mud. And one more problem that is important is if the PAM Puspiptek failed to supply fresh water to the reactor. So to handling and anticipate these things, necessary to optimize the deep well former Interatom legacy as a backup water supply for raw water supply system of the reactor. With a conductivity of 136 μS / cm, pH 7,4 and total hardness 37 ppm, the water from deep wells can be used as a backup supply of secondary raw water cooling system. (author)
