Enclosure REVISED AGENDA Monday, September 23, 1985 8:00 a.m. . Introductions, short entrance briefing (15 minutes) by NRC, short overview of program and current status by Gulf States Utilities (GSU) (45 minutes) 9:00 a.m. Item 1 (PSRB)

General Information Needed:

Short overview of the parameter selection process with emphasis on plant-specific considerations, especially regarding the validation of the parameter set in terms of representativeness and useability at Riverbend.

Specific Information Needed:

Identify any differences between the generic G.E. SPDS and the Riverbend SPDS parameters. Describe plant-specific plans for the validation of the parameter set, i.e. how did/will GSU confirm that the generic parameter set is sufficient for use at Riverbend and is adequately representative and useable for Riverbend operators.

Discuss whether beyond-design-basis conditions have been factored into the validation program, e.g. venting primary containment at high pressure, level measurements below top of active fuel.

11:00 a.m. Item 2(HFEB)

General Information Needed:

Discussion of Human Factors Review and user needs analysis.

Specific Information Needed

Identify and discuss any modifications to the generic G.E. ,

SPDS that were needed for plant-specific consistency, e.g.

plant or utility conventions for color-coding, abbreviations, symbols, etc.

Discuss the methodology used to confirm that Riverbend operators can readily and reliably assess plant status using the SPDS, and that the displayed information is easily perceived and comprehended.

12:00 p.m. Lunch e

.. o l

1:00 p.m. Item 3 (HFEB/ICSB/PSRB) .

l, ..

General Information Needed:

Discussion of data validation techniques used.

Specific Infonnation Needed:

i Identify and discuss any differences between the data i validation techniques used in the generic G.E. design and

the Riverbend SPDS.. including numbers of redundant inputs, unavailable inputs, modifications to weighting and compensation algorithms, etc.

2:00 p.m. Item 4 (HFEB/ICSB)

General Infonnation Needed:

Short discussion of system availability i Specific Infonnation Needed i

Estimates of availability, plant-specific. Plans for retaining high availability throughout the system

life-cycle:

a a software maintenance i b hardware maintenance l c configuration control j

d technician /progransner training programs for ERIS/SPDS

! 3:00 p.m. Demonstration of operational portions of SPDS at the simulator /TSC/ Control Room or other convenient location.

1 l 8:30 a.m.  ; Resolution of items remaining from Monday session, further

, questions from staff, further questions to the staff.

9:30 a.m. Further demonstration of operational portions of SPDS, including a walk-through/ talk-through of a scenario that 1

involves monitoring radiation levels in the reactor building i

and determining whether there has been a significant off-site release (alert level or greater). GSU should develop this scenario. The scenario should exercise several

plant-specific E0Ps.

12

00 p.m. Lunch 1:00 p.m. Staff review of SPDS displays, fonnats, and interface i devices. At least one knowledgeable person from GSU should l be present to answer questions from the staff.
