Capsule and pot boiler tests were conducted to develop and to evaluate shutdown soak solutions and procedures for limiting dent growth in nuclear steam generators. Testing was limited to isothermal soaking in the absence of boiling heat transfer. The effect of intermittent boiling produced by pressure or temperature cycling was not evaluated. Capsule tests of hydrazine-treated water and of alkaline phosphate solutions were conducted at 150/sup 0/F and 565/sup 0/F for soak times of 1, 4 and 7 days, and for phosphate concentrations ranging from 50 to 10,000 ppM PO/sub 4/. Four day, low temperature soaks in wet layup, 1000 ppM PO/sub 4/ and 3000 ppM PO/sub 4/ were tested in pot boilers with active denting.
