For the Setpoint that is not determined to be SL-Related: Describe the measures to be taken to ensure that the associated instrument channel is capable of performing its specified safety functions in accordance with applicable design requirements and associated analyses. Include in your discussion information on the controls you employ to ensure that the As-Left trip setting after completion of periodic surveillance is consistent with your setpoint methodology. Also, discuss the plant corrective action processes (including plant procedures) for restoring channels to operable status when channels are determined to be "inoperable" or "operable but degraded." If the controls are located in a document other than the TS (e.g., plant test procedure), describe how it is ensured that the controls will be implemented. | | : 2.

Monticello - Draft RAI re. Recirc. Riser Differential Pressure, Instrumentation (TAC MD6864)
Rick:
We are continuing our review of your license amendment request associated with Function 2.j, Recirculation Riser Differential Pressure - High (Break Detection) in TS 3.3, Emergency Core Cooling System Instrumentation, Table 3.3.5.1-1. By previous e-mails (3/18/03 and 3/27/08) I transmitted draft RAI questions generated by reviewers L. Ward and T. Nakaishi, and we are still waiting for response to those. Meanwhile, our Instrumentation and Controls Branch reviewers Kerby Scales and Barry Marcus have generated the following draft RAI questions; please set up a telephone conference with me to discuss these draft questions:
- 1. Setpoint Calculation Methodology: Provide documentation (including sample calculations) of the methodology used for establishing the limiting setpoint (or NSP) and the limiting acceptable values for the As-Found and As-Left setpoints as measured in periodic surveillance testing as described below. Indicate the related Analytical Limits and other limiting design values (and the sources of these values) for each setpoint.
- 2. For the Setpoint that is not determined to be SL-Related: Describe the measures to be taken to ensure that the associated instrument channel is capable of performing its specified safety functions in accordance with applicable design requirements and associated analyses. Include in your discussion information on the controls you employ to ensure that the As-Left trip setting after completion of periodic surveillance is consistent with your setpoint methodology. Also, discuss the plant corrective action processes (including plant procedures) for restoring channels to operable status when channels are determined to be inoperable or operable but degraded. If the controls are located in a document other than the TS (e.g., plant test procedure), describe how it is ensured that the controls will be implemented.
The sole purpose of this e-mail is to prepare you and others for the proposed telephone conference. With or without the conference, we plan to formally issue an RAI to you around July 25. Thus, this e-mail does not formally request for additional information or convey an NRC staff position.
