SUBJECT:
HUMAN FACTORS ENGINEERING BRANCH STATUS REPORT IrdPUT FOR V0GTLE, UNITS 1 AND 2 DRAFT SER There is currently insufficient information to prepare a human factors engineering evaluation of the Detailed Control Room Design Review (DCRDR),
the Safety Parameter Display System (SPDS) or a SALP evaluation.
In lieu of such an evaluation, a status report is provided for inclusion in the draft SER (see enclosure).
Georgia Power has submitted a DCRDR Program Plan, dated September 14, 1984, for NRC review as required by Supplement i to NUREG-0737, " Requirements for Emergency Response Capability" (Generic. Letter No. 82-33).
The applicant has indicated that a DCRDR Suranary Report would be submitted in March 1986 for Unit 1 and September 1987 for Unit 2.
The applicant intends to submit its SPDS implementation plan and safety analysis for both units in September 1985. HFEB will review these reports, make decisions regarding audits, and keep the Division of Licensing informed accordingly.
This status report was prepared by James A. Hoyt, Jr., of the Human Factors Engineering Branch.

HUMAN FACT 0P.S ENGINEERING BRANCH IliPUT FOR V0GTLE, UNITS 1 AND 2 DRAFT SER 18-HUMAN FACTORS ENGINEERING All licensees and applicants for an operating license are required to conduct a Detailed Control Room Design Review (DCRDR) and to provide a Safety Parameter Display System (SPDS) in response to NRC Task Action Plan Item I.D.1 ana I.D.2 (NUREG-0660, May 1980; and NUREG-0737,
- November 1980 as supplemented by Generic Letter 82-33, December 17, 1982). The purpose of the DCRDR is to identify and correct human engineering discrepancies (HEDs) which might affect the operator's '
ability to prevent or cope with an accident.
DCRDRs should be conducted using the guidence provided in NUREG-0700, " Guidelines for Control Room Design Reviews," dated September 1981 or equivalent guidance.
The purpose of the SPDS is to continuously display information from which plant safety status can be readily and reliably assessed.
The principal function of the SPDS is to aid control room personnel during abnormal and emergency conditions in determining the safety status of
(-
the plant and in assessing whether abnormal conditions warrant
-corrective action by operators to avoid a degraded core. A written SPDS safety analysis shall be prepared describing the basis on which the selected parameters are sufficient to assess the safety status of each identified function for a wide range of events including symptoms of severe accidents.
In response to Supplement 1 to NUREG-0737, Georgia Power has negotiated with the NRC the following schedules for meeting its DCRDR requirement.
.fr A DCRDR-Program Plan was submitted, dated September 14, 1984, for Units 1 and 2 and is currently under staff review. A Summary Report will be submitted in March 1986 for Unit 1 and September 1987 for Unit 2.
A Summary Report will be submitted in March 1986 for Unit 1 and
. September 1987 for Unit 2.
Following a review of the applicant's Program Plan, the HFEB staff will conduct an in-progress audit of the DCRDR Program.
Then, based on an assessment of the applicant's DCRDR Summary Report and the in-progress audit report, the HFEB staff will decide if a pre-implementation audit is required.
This cecision wil,1 be made, and the licensee informed, within.two weeks after the HFEB's
, receipt of the Summary Report.
If the pre-implementation audit is required, it will be accomplished within one month after receipt of the Summary Report.
The HFEB Staff will issue a SER two months after receipt of the applicant's Summary Report, Georgia Power has committed to submiting an SPDS Implementation Plan and safety analysis for both Units in September 1985. The NRC will review this Plan to confirm:
(1) the adequacy of the parameters selected to be displayed to detect critical safety functions; (2) that means are provided to assure that the data displayed are valid; (3) the adequacy of the design and installation of the system from a human factors perspective; (4) that the SPDS will be suitably isolated from electrical and electronic interference with equipment and sensors that are used in safety systems; and (5) the adequacy of the verification and
,, a,-
. 't' 3-validation (V&V) program to assure a highly reliable SPDS.
The projected dates for the SPDS becoming operational and for completion of training is September 1986 for Uriit 1 and March 1988 for Unit 2.
