SUBJECT:
ISSUANCE OF AMENDMENTS (TAC NOS. M96228 AND M96229)
Dear Ms. Johnson:
j The U.S. Nuclear Regulatory Commission (Commission) has issued the enclosed Amendment No. 177 to Facility Operating License No. DPR-39 and Amendment i
No. 164 to Facility Operating License No. DPR-48 for the Zion Nuclear Power 1
Station, Units 1 and 2, respectively. The amendments are in response to your application dated July 26, 1996, as supplemented on September 3, 1996, September 18, 1996, two submittals dated October 14, 1996, October 22, 1996, two submittals dated November 8,1996, and December 17, 1996.
The amendments allow Commonwealth Edison Company (Comed) to control the reactor coolant system pressure and temperature limits for heatup, cooldown, low temperature operation and hydrostatic testing. They also revise the reactor vessel material surveillance program specimen withdrawal schedule such that the Unit 2 removal of capsule X is delayed until 19 Effective Full Power Years.
For Zion, Unit 1, weld WF-154, Comed t. sed surveillance data from the Point i
Beach, Unit 2, surveillance program to determine the chemistry factor. The staff has concluded that an adjustment in the chemistry factor for the Zion welds of +13 degrees Fahrenheit to account for the 13 degrees Fahrenheit difference in irradiation temperature between the Point Beach, Unit 2, surveillance capsules and the Zion vessel, should have been factored into the calculations. This adjustment is reflected in the enclosed safety evaluation.
The amendments are satisfactory for implementation because this adjustment does not affect the pressure-temperature limit curves. However, depending on future surveillance capsule results, it is possible that it could become limiting. Therefore, in future calculations using surveillance data from Point Beach, Unit 2, an adjustment in the chemistry factor should be made to account for the difference in irradiation temperature.
In its letter dated December 17, 1996, the licensee agreed to this change in methodology.
If this causes a change in the limiting weld, Comed is requested to notify the staff.
