• MAR 101996 Docket Nos.: 50-424 and 50-425 APPLICANT: Georgia Power Company FACILITY: Vogtle, Units 1 and 2

SUMMARY

OF SPDS/DCRDR MEETING HELD FEBRUARY 26, 1986 The NRC staff met with the applicant on February 26, 1986 to discuss the Vogtle Safety Parameter Display System (SPDS) and the Detailed Control Room Design Re-view (DCRDR). Participants are listed in Enclosure 1.

The applicant explained in its presentation that the Emergency Response Facility (ERF) computer and the SPDS are not interchangeable but that the ERF computer is the hardware providing the display for the SPDS. The applicant stated that SPDS information is available in the control room, technical support center, and emergency operations facility simultaneously.

The SPDS is based on 6 critical safety functions. The system utilizes a color priority scheme; green indicates a satisfactory condition, red indicates a severe challenge, orange means a lesser challenge and yellow signifies an alert condition. Purple indicates bad data. The SPDS responses have been integrated with the plant emergency operating procedures.

The applicant stated that its SPDS is based on similar hardware and software at some of its fossil plants. The staff asked how comparable the Vogtle SPDS was to the Hatch SPDS. The applicant stated that it would look into this.

EG&G Idaho has been contracted by Georgia Power Company to perform an indepen-dent verification and validation effort of the SPDS scheduled for completion in September 1986. The Vogtle system has already been subjected to simulator trials and is now used at the Vogtle simulator for training. The SPDS was utilized last spring during the verification and validation of the emergency procedures.

The applicant stressed what it believes to be the ease of use of the SPDS for the operator in the form of one-button callup of information. The digital display utilizes red to indicate an out of bounds parameter and green to in-dicate a satisfactory parameter. A bar chart display can be used to show parameters as less than or greater than normal.

In a post-trip situation, the shift technical advisor will be the principal user and will monitor critical safety functions. .

The status of the critical safety parameters is always displayed on at least one of the screens on the floor of the control room due to an interlock which requires this. The SPDS system is capable of retaining a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> time history for trending ir. formation. The system autoscales the data to fit it all on the screen. Unless otherwise specified, the system will default to provide ten minutes of data. The staff questioned why normal values were not shown on some screens to provide operator guidelines. The applicant answered that the operators would be trained to be familiar in general with such information or be able to obtain it.

The overview of the radiological safety function shows a plant mimic with approximate instrument locations. The SPDS also has special functions in-cluding basic flow diagrams. Available displays include steam generator flow paths, pressurizer, component cooling water, auxiliary component cooling water, safet'y injection system pump flow, boron injection tank, accumulators, and the residual heat removal system. Additionally, amplifying information is available such as reactor coolant system inventory and meteorological tower data.

A hard copy output of any display is available but not in color.

The staff asked if residual heat removal flow was a top level parameter. The applicant explained that it was not but that it was on a special display available through one-button callup.

The staff requested that the applicant provide the EG&G verification and vali-dation report to the staff when it becomes available in September. The staff also requested that the SPDS validation algorithms be provided. The applicant indicated that these would be provided promptly. The applicant indicated that human factors aspects of the SPDS would be discussed in the DCRDR sumary report. The staff discussed the possibility of a site visit later this year to view the SPDS. The applicant's overhead slides on the SPDS are provide in Enclosure 2.

i Enclosure 3 ' cont 31ns the applicant's overhead slides from its presentation on the DCRDR. The applicant indicated that a human factors specialist is now assigned full-time to the DCRDR effort and that additional technical and clerical help has been obtained. The applicant has also utilized a computer to aid in tracking and controlling aspects of the DCRDR. including the task analysis, inventory, engraving list and modifications.

The applicant stated that Westinghouse is to provide the list of needed in-strument characteristics to Georgia Power Company in March. The applicant )

will use this list for comparison of actual control room instrumentation. The i NilREG-0700 surveys are complete except for those which must be deferred until the control room is complete such as the comunications, lighting, and noise I surveys. The Sumary Report is scheduled for a May submittal to the staff. '

The remaining surveys will not be complete until October 1986 and will there-fore be addressed in a supplement to the Sumary Report.

The staff and applicant also reviewed the status of responses to staff iden-tified issues in its letter of September 26, 1985.

.The staff indicated that the progress made on the Vogtle DCRDR is promising and appears to be satisfying staff requirements. The staff expressed a possible interest in a second DCRDR site visit following submittal of the Sunnary Report. l l
