EMERGENCY FEEDWATER (EFW) SYSTEM TECHNICAL SPECIFICATION (TS) CHANGE REQUEST DOCKET NO. 50-289

1. What is the minimum amount of time allowable for an individual to realign the valves to their operational positions in the event an EFW transient were to occur while performing this surveillance test? Also, please clarify: Using Figure 1 from the licensees December 19, 2001, submittal as a basis, identify which valves require manual actions and the relative distances between them. Also, identify the transit time between valves and, how much time and effort are required for an individual to manually realign each valve?
2. What is the basis for determining that an individual can successfully and reliably accomplish the required actions in the minimum allowable time under conditions that simulate the real event? For example, during an EFW transient event, are there harsh environmental factors such as radiation, excessive heat, noise, etc., that would hamper an individual from performing the required manual valve realignment and, if there are impediments, have they been considered in determining whether an individual can perform the required actions?
3. What are the consequences if the individual fails to perform the actions (i.e., valve realignment) in the allotted time?
4. The licensee (page 4 of 6 of Attachment 1 of the December 19, 2001, submittal) defines the individual performing the EFW surveillance as follows:

A dedicated qualified individual is defined in the revised Bases to be one who is involved exclusively with the EFW surveillance testing....."

However, the individual is not solely responsible for valve realignment but also has as his principal responsibility, EFW testing. The licensee, in its response, has changed the meaning of the term "dedicated" from its previous usage (see Attachment 3 of the licensees December 19, 2001 submittal, the licensees December 6, 2000, submittal, discussion on page 14 of 20). The individual, as described by the licensee in its December 19, 2001, submittal, is "designated," not dedicated because he has additional responsibilities relative to the function of valve realignment. Either term and set of responsibilities is appropriate, i.e., either the individual is "dedicated" exclusively to the valve manipulation, the action for which the licensee is seeking credit or, the individual is "designated" (i.e., can perform other tasks in addition to the principal task (which is valve realignment) such as EFW testing).
