Joel, I work for Bill Crouch and he has assigned one of the NRC PM Open Items List items to me.

It simply says Control Room Lighting RAI.

Earlier today, I was compiling a list of RAIs for which we owe yall a response. In doing so, I reviewed a group provided by e-mail from Lamb dated 05/27. The last RAI in this group was as follows:

Section 9.5.3 - Lighting System

1. Provide a summary discussion of the typical luminance ranges for normal and emergency lighting in all areas/rooms of the plant to ensure that the functional capability of the lighting system design provides illumination level in accordance with the IESNA Lighting Handbook for Central Stations or NUREG 700. Discuss the technical basis if the design illumination levels are not in conformance with the guidelines of IESNA Lighting Handbook for Central Stations and NUREG 700.

Section 9.5.3 of the WBN Unit 2 FSAR does not describe the illumination levels for the work areas or type of tasks in the Main Control Room (MCR), safety-related panels in the MCR and remote shutdown consoles. Provide a description of the illumination levels for normal lighting in these areas. Discuss the technical basis if the design illumination levels do not conform to the 1

guidelines of IESNA Lighting Handbook for Central Stations or NUREG 700.

Discuss if the emergency lighting in the MCR, safety-related panels in the MCR and remote shutdown consoles provides illumination levels in these areas equal to greater than those recommended by the IESNA Lighting Handbook for Central Stations or NUREG 700 for at least 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.

Please confirm that this is the RAI that the subject of the PM Open Item mentioned above.

If this is not the one, please provide me with more information.
