I know hydrogen gas is used in BWR coolant to counteract radiolysis and reduce the probability of localized corrosion. Why can't the same be done for PWR's?
Why is hydrogen added to BWR coolant but not PWR coolant?

Hydrogen is added to PWR primary coolant systems. There is a slight overpressure of hydrogen (25-35 ml/kg, in solution) in PWR coolant.
One can find a number of reports on EPRI's website - search for "PWR primary water chemistry guidelines" - http://www.epri.com/search/Pages/default.aspx

From the old Westinghouse PWR Technology Manual:
