Emergency Response Data System (ERDS) - Revision to Previously Submitted DataPoint Library Information

Nuclear Management Company, LLC (NMC) is submitting a revised Data Point Librarysoftware specification for the Monticello Nuclear Generating Plant (MNGP). Thefollowing is a summary of the change:

1. Deletion of "Drywell Vent Coolers" from ERDS for PCT138 (DW Equip DrainSump Volume) on sheet Number 17.

The revised ERDS software requirement specification (ERDS-SRS-1-6) is required tobe reported to the USNRC within 30 days of the software change. The change wasapproved with an effective date of January 17, 2005.

This letter makes no new commitments or changes any existing commitments.

II. Selection of Data Feeders

A. How many data feeders are there (six maximum)?

One - Process Computer System

B. 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

2. the rationale for selecting it if another system can also provide its categories ofdata points.

a) It is planned to provide both plant data points and meteorologicalinformation through the single feeder.

b) No other system is capable of providing requested information.

C. Which data feeder is the site time determining feeder? This should be the feeder whichis providing the majority of the data points.

C. Data Communication Details

1. Can this data feeder provide asynchronous serial data communication (RS-232-C) with full-modem control?

Yes

2. Will this feeder transmit in ASCII or EBCDIC?

ASCII

3. Can this feeder transmit at a serial baud rate of 2400 bps? If not, at what baudrate can it transmit?

Yes, 2400 bps can be used.

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

Yes

a) Are any problems foreseen with the NRC using XON/XOFF to control thetransmission of data?No, however the use of SUSPEND and RESUME to control thetransmission of data works better as demonstrated in testing withHaliburton/NUS.

5. If it is not feasible to recontigure a serial port for the ERDS linkup (i.e., changethe baud rate, parity, etc.), please explain why.

Note Applicable.

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

Yes

a) If not, is it possible to add additional ports?

Not Applicable.

D.

b) If yes, will the port be used solely by the ERDS or shared with other non-emergency-time users? Give details.

Port will be dedicated for ERDS.

Data Feeder Physical Environment and Managlement

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

Computer Room located in Plant Administrative Building adjacent to Plant ControlRoom.

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

Yes, PCS is provided with UPS (batteries with inverter and diesel generator).

3. Is there a human operator for this data feeder?

Yes

a) If so, how many hours a day is the feeder attended?

It is planned to have the Shift Emergency Communicator (SEC) initiate theERDS System per Emergency Implementing Procedures. An SEC is onduty 24 hours/day.
