Dear Mr. Eisenhut:
Philadelphia Elcetric Company has reviewed the Limerick Generating Station Units 1 0 2 coolant pressure boundary piping and fitting material, including wel metal, to determine conformance with the material selection and process guidelines set forth in NUREG-0313, Revision 1, dated July, 1980 and transmitted bv ur 1ctter of February 26, 1981.
Our review covered the following systems:
1.

These systems meet the requirements of NUREG-0313, Revision 1 with the following exceptions:
1.
Type 304 stainicss steel has been used between outboatd and inboard isolation valves on the RIIR, LPCI, and Core Spray Systems.
2.
Valve FOOD on the RilR Shutdown Cooling Suction Line is made of forged type 316 stainicss steel.
In these cases the temperature during normal operations is below the threshold temperature for IGSCC occurrence.
