Hydrogen gas is utilized in Boiling Water Reactor (BWR) coolant to mitigate radiolysis and decrease localized corrosion risks. In contrast, Pressurized Water Reactor (PWR) systems incorporate hydrogen in the primary coolant at a concentration of 25-35 ml/kg, but not to the same extent as in BWRs. This difference is due to the distinct chemical environments and operational requirements of BWRs and PWRs. For further details, refer to the EPRI's primary water chemistry guidelines and the Westinghouse PWR Technology Manual.
