282.0 282.1 To evaluate the compatibility of the control rod drive structural 4.5.1 materials with the reactor coolant water, provide the list of materials and specifications which are used for each co ponent of the control rod drive mechanism.
The information in the FSAR does not adequately identify the materials.
282.2 Provide the following on your secondary water chemistry control and 10.3.5 monitoring programs:
1.
Sampling 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 critical parameters; 3.
Procedure for the recording and management of data; 4.
Procedures defining corrective actions
- for off-control point chemistry 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.
'f
- Branch Technical Position MTEB 5-3 describes the acceptable reans 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 MILB 5-3 (96-hour time limit to repair or plug confirmed condenser tube leaks).
