April 18, 2012 Monticello Nuclear Generating Plant 2807 W County Road 75 Monticello. MN 55362 L-MT-12-035 10 CFR 50 Appendix E.Vl.3.a U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555-0001 Monticello Nuclear Generating Plant Docket 50-263 Renewed Facility Operating License No. DPR-22 Emeraencv Response Data Svstem-Data Point Librarv Update Pursuant to the requirements of 10 CFR 50, Appendix El Section V1.3, "Maintaining the Emergency Response Data System," the Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, the licensee for the Monticello Nuclear Generating Plant (MNGP), is submitting this letter to inform the NRC of updates to the Emergency Response Data System (ERDS) data point library implemented April 1, 2012. The ERDS data point library was revised to document replacement of 16 Meteorological Information and Dose Assessment System (MIDAS) computer points with Radiological Assessment System for Consequence Analysis (RASCAL) computer points. Enclosure 1 contains a summary of the revised computer points. Enclosure 2 contains a copy of the updated ERDS Data Point Library.
Summarv of Commitments r revisions to any existing commitments.

the rationale for selecting it if another system can also provide its categories of I
data points.
a)
It is planned to provide both plant data points and meteorological information through the single feeder.
a)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 which is providing the majority of the data points.

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 ASCll or EBCDIC?
- 3.
Can this feeder transmit at a serial baud rate of 2400 bps? If not, at what baud rate can it transmit?
Yes, 2400 bps can be used.
- 4.
Does the operating system support XONIXOFF flow control?
Yes a)
Are any problems foreseen with the NRC using XONIXOFF to control the transmission of data?
No, however the use of SUSPEND and RESUME to control the transmission of data works better as demonstrated in testing with HaIiburtonINUS.
- 5.
If it is not feasible to recontigure a serial port for the ERDS linkup (i.e., change the 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.

65 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.
D.
Data Feeder Physical Environment and Management I
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 Control Room.
- 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 the ERDS System per Emergency Implementing Procedures. An SEC is on duty 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />slday.
