ENCLOSURE SNUPPS - WOLF CREEK PLANT, UNIT 1 2P,2.0 wc CORROSION ENGINEERING 282.1 sc To evaluate the compatibility of the control rod drive structural 4.$.1 materials with the reactor coolant water, orovide the list of r.aterials and soecifications which are used for each comoonent of the control rod drive mechanism.

The information in the FSAR dces not adecuately identify the materials.

282.2 wc Provide the following on your secondary water chemistry control and 10.3.5 monitoring programs:

1.

Samoling schedule for the critical parameters and of control points for these parameters for the cold startup mode of operation; 2.

Procedures used to measure the values of the cri+.ical parar.eters; 3.

Procedure for the recording and management of data; 4

Procedures defining corrective actions

• for off-control coint chem'i~stry conditions; and 5.

A procedure identifying (a) the authority responsible for the inter-pretation of the data and (b) the sequence and timing of administra-tive events required to initiate corrective action.

Verify that the steam generator secondary water chemistry control program incorporates technical recommendations of the NSSS. Any significant deviations from NSSS recommendations should be noted and justified technically.

• Brancn Technical Position MTEB 5-3 describes the acceptable means for monitoring secondary side water chemistry in PWR steam generators, including corrective actions for off-control point chemistry conditions.

However, the staff is amenable to alternatives, particularly to Branch Technical Position B.3.b(9) of MTEB 5-3 (96-hour time limit to reoair or plug confirmed condenser tube leaks).
