The operation of self-actuated pressurizer steam relief valve of the Shippingport PWR was tested within a prescribed setting of 2300 plus or minus 50 psig. The valve popped at 2265 psig and reseated at 2190 psig, with a time lapse of 12.9 seconds between popping and reseating. Leak rates before and after popping of the valve were 0.70 gallons/ hour and 1.35 gallons/hour, respectively. The valve performed reliably in that it popped within the prescribed setting and reseated with no observable valve chatter or flutter. (auth)
