South Texas Project required new shielding for a section of the pressurizer spray line. Though the area looks small, the total shield weight was around 850 lb (386 kg). This was due to the 6.5″ (165 mm) diameter of the pipe and the 1.5″ (38 mm) thick shielding pieces. But despite the size and weight of the pieces, installation was a breeze. The elbow sections fit perfectly and all the sections were secured with cinch straps to a tight fit and effective shielding. STP saw dose reduction between 56%-63% on contact and 56%-70% at 30 cm, right in line with our dose reduction estimate of 60%. This made the shielding package a success.
