- Docket No. 50-244 Rcf.(a): NUREG-1394, Revision 1, Emergency Response Data System Tmplementation, June 1991 (b): Letter f rom R. C . Mecrady, RG&E, to A.R. Johnson, NRC, subject: Submittal of. Data Point Library Sheets, dated-February 28, 1992

Dear Mr. Johnson:

Enclosed is the information required in reference (a), Appendix B.

Also enclosed are the quality codes - and descriptj ons for- our Plant-Process Computer System (PPCS) at Ginna Station.- Based on our october 18, 1991 meeting with the NRC and-Halliburton NUS at King of Prussia, PA, the NRC will use the quality codes as they appear on the PPOS. Please inform us if there are limitations-on the number of etuality codes that the NRC can accept.

Ve truly yours,.

Please givelboth the acronym and the words forming it.

PPCS - Plant Process Computer System L .

b. Is-this the site time det'rmining e feeder?

No l

i l t-

c. How of ten will this feeder transmit an update set to the-ERDS (in seconds)?

i-One transmission /60 seconds

2. Hardware / Software Environment l a. Identify the' manuf acturer and model number of the data j feeder hardware.

i Gould SEL 6780 i

b. T.dentify the operating system.

MPX 3.2 B

c. What method of timekeeping is implemented on this feeder system (Daylight Savings, Standard, Greenwich)?

Eastera; Standard / Daylight Savings Time

. d.. In what time zone is this feeder located?

l Eastern

j. 3. Data Communication Details

a. Can this data feeder provide a synchronous serial data I communication (RS-232-C) will full-modem control?

Yes

b. Will this feeder transmit in ASCII or EBCDIC 7~ ,

ASCII

! c. Can this feeder transmit at a serial baud - rate of ' 240 )

bps? If not, at what baud rate can it transmit?.

2400 bps

d. Does the operating-system support XON/XOFF flow control?

l

-Yes

-1.- Are any problems foreseen.with the NRC'using XON/.

XOFF-to control-the transmission of. data?

No-L , . _ _ _ _

c. If it is not feasible to reconfigure _a serial port for the ERDS linkup (i.e. change the baud rate, parity, etc.), please explain why.

N/A; The port will be configured for the ERDS linkup

f. Do any ports currently exist for the ERDS linkup?

d No '

1. If not, is it possible to add additional ports?

Yes

2. If yes, will the port be used solely by the ERDS or shared with other non-eu.ergency-time users? _Give details.

Used solely for ERDS

4. Data Feeder Physical Environment and Management

a. Where is the data feeder located in terms of the TSC, EOF, and control room?

TSC Computer Room

b. Is the data feeder protected from loss of supply of electricity?

Yes. The PPCS is powered f rom the Technical - Support Center Uninterruptible Power Supply

c. Is there a human operator for this data feeder? i Yes

1. If so, how many hours a day-is the, feeder attended?

22 SUB Green A substirute value has been entered for Point.

24 DALM Green Point is deleted from all alarm processing.

25 INHB Green Point is in an abnormal condition, but alarm generation is inhibited via cut-out point.

26 OTT Green Open thermocouple hardware test-was in progress when point was scanned.

29 GOOD Green Point is normal, J.c., passes all above tests.

Suspect Data Bias In the RG&E PPCS system, additional provision is made to identify certain data points whose values are considered to be " suspect"'or-questionable. Examples of suspect data. points are:

1. a calculated point where one or more of-the-argument points used in the calculation has a " white" data quality code and, hence, the " white" point.was excluded-from the calculation'.

2. cn average-value calculation where one er more of the point values used in the calculation -differed by more than _a specified tolerance from the average value and war excluded-from the calculation.

" Suspect" data points are considc; ed as valid -points for use. in

, _other - point calcu?ations._ " Suspect quality - codes . of argument points in calculations are p mogated to the calculated point.

The quality code of a suspect point will be biased by 128. For example:

GOOD code = 29 SUSPECT bias = + 128 quality code = 157 Alarm Posted Bias

' An " alarm'- posted bias" of 32 - may also be included in the data quality code. The alarm bias is-for internal alarm processing and should be ignored by the NRC. For example:

GOOD code = 129 posted bias = + 32 quality code = 61
