Subject:
Emergency Response Data System (ERDS) Gentlemen: In Reference (b), New Hampshire Yankee (NHY), the predecessor company to North Atlantic Energy Service Corporation (North Atlantic) submitted an Implementation Plan for the Emergency Response Data System (ERDS) at Seabrook Station, and requested a schedular exemption from the ERDS Rule [ Reference (c)]. The NRC granted the schedular exemption in Reference (d). Accordingly, the ERDS is scheduled to be implemented at Seabrook Station prior to restart following the third refueling outage, but no later that December 1,1994. Reference (b) forwarded a partially completed Site Survey Questionnaire (Appendix B to NUREG-1394, Revision 1), which included all information available at the time. This letter - submits an updated Site Survey Questionnaire containing all the requested information for Seabrook Station. Should you have any questions regarding this matter, please contact Mr. Terry L. Harpster, Director of Licensing Services, at (603) 474-9521, extension 2765.

4 j I ') l III. Selection of Data Feeders A. How many data feeders are there (six maximum)? One Data Feeder 1 It Identify the selected data feeders and provide the following for each: (1) a short description of the categories of data points it will provide (e.g. met, rad, or plant data points, by unit) and The Main Plant Computer System (MPCS) Communications Processor receives the entire data base from the MPCS once per second and handles all external data services. The data base includes met data, radiation data from the RDMS, RVLIS data and plant data points, r (2) the rationale for selecting it if another system can also provide its categories of data points. The MPCS is the central depository of all process data including data links from other systems. The MPCS/ Communications Processor also provides data to the EOF and TSC. i C. Which data feeder is the site time determining feeder? This should be the feeder which is providing the majority of the data points. MPCS/ Communications Processor. .B-7 NUREG-1394, Rev.1
A A l t i I i IV. Data Feeder Information Note: A new Section IV must be filled out for each feeder system selected. General Questions 1. Identification of Data Feeder I a. What is the name in local parlance given to this data feeder (e.g., Emergency Response Information System)? Please give both the acronym and the words forming -9 it. Main Plant Computer System (MPCS)/ Communications Processor b. Is this the site time determining feeder? i Yes c. How often will this feeder transmit an update set to the ERDS (in seconds)? l 15 seconds 2. IIardware/ Software Environment a. Identify the manufacturer and model number of the data feeder hardware. Digital Equipment Corporation (DEC) VAX 4000 Model 200 b. Identify the operating system. DEC VAX/VMS Version 5.5 c. What method of timekeeping is implemented on this feeder system (Daylight Savings, Standard, Greenwich)? Daylight Savings Time d. In what time :rone is this feeder located? Eastern 5 4 NUREG-1394, Rev.1 B-8 l u
.j 2-y a .i 3. Data Communication Details a. Can this data feeder provide a synchronous serial data communication (RS-232-C) with full-modem control? Yes n b. Will this feeder transmit in ASCII or EBCDIC? i . ASCII a c. Can this feeder transmit at a serial baud rate of 2400 bps? If not, at what baud rate I can it transmit? Yes d. Does the operating system support XON/XOFF flow control? f I Yes 1. Are any problems foreseen with the NRC using XON/XOFF to control the' transmission of data? No e. 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 f. Do any ports currently exist for the ERDS linkup? j Yes 1. If not, is it possible to add additional ports? 1 N/A I 3 3 i B-9 NUREG-1394, Rev.1
.l 1 l 2. If yes, will the port be used solely by the ERDS or shared with other non- - emergency-time users? Give details. The Port will be used solely by ERDS. l 4. Data Feeder Physical Environment and Management i a. Where is the data feeder located in terms of the TSC, EOF, and control room? l The MPCS is located in the Seabrook Station Computer Room. The TSC and the control room are adjacent to the computer room. The EOF is located in Newington - NH, approximately 14 miles away. i b. Is the data feeder protected from loss of supply of electricity? Yes - UPS unit backed up by diesel generator. c. Is there a human operator for this data feeder? Yes, by on-site computer support personnel. 1. If so, how many hours a day is the feeder attended? 1 Nine hours per day on weekdays. Call-in coverage weekends, i NUREG-1394, Rev. ! ' B-10 i}}
