PPAIRIE IS1AND NUCLEAR GENERATING PLANT Docket Nos. 50 282 License Nos. DPR-42 50 306 DPR-60 Emergency Response Data System Implementation Plan In accordsn?o with th< requirements of Section VI 4.a of Appendix E to 10 CFR E Part 50, this 'atter submits the Emergency Response Data System implementation program plen .% Prairie Island Units 1 and 2. The implementation program plari is pr::v'.ue1 as Attachment 1.

In support -f the implementation program plan, a response to the site survey questionTaire included in Revision 1 to NUREG-1394, " Emergency Response Data Syseem (ERD!s) 1mple'nentation", which includes plant attribute information, is provided ao / t.tachment 2.

Data Point Libraries for Prairie Island Unite 1 and 2, which were assembled in accordance with the guidelines of Revision 1 to NUREG-1394, are provi/ed in Attachments 3 and 4.

In our March 14, 1990 response to Generic Letter 89-15, " Emergency Ret 7onse Data System", NSP volunteered to connect Prairie Island Units 1 and 2 to the Emergency Response Data Syster and stated that the connection to Prairie Island Units 1 and 2 was scheduled to be available in 1991.

K-That proposed schedule is not consistent with the current NRC schedule for implementation or the subsequent requirements and guidance provided by Section VI.4.a of Appendix E and NUREC-1394. Therefore, we consider the schedule outlined in the atteched implea.entation program plan to supersede the schedule related commitments mac'e in our March 14, 1990 response to Ceneric Letter 89-

Emergendy Response Data System Implementation Program Plan Section VI.4.a of Appendir E to 10 CFR Part 50 requires that each licensee develop and submit an Emergency Response Data System implerentation program plan to the NRC by October 28, 1991, The Emergency Response Data System implementation program plan for Prairie Island Units 1 r.nd 2 is described below, l

Section 50.72.a.4 of 10 CFR Part 50 specifies that the licensee shall activate the Emergency Response Data System as soon as possible but not later than one hour after declaring an emergency class of alert, site area emergency or general emergency. The Prair!.e Island Emergency Plan Implementing procedures (EPIP) will-be modified to ensure that the Emergency Response Data System is

, actuated within the time requirements of 10 CFR Part 50 Section 50.72.a.4, Prairie Island will utilize existing section work instructions to ensure the integrity of the Emergency Response Data System hardware and software configuration is maintained. The computer gtoup section work instructions will be modified to include provisions for NRC review of-system modifications which could affect the data communication protocol at least 30 days prior-to the modification. The computer group section work instructions will also be changed to ensure that changes to the Data Point Library are submitted using the Data Point Library Reference File Form within 30 days of the change.

The eleven steps, outlined in Revision 1 to NUREG-1394, for the implementation of the Emergency Response Data System are being addressed for Prairie Island Units 1 and 2 as follows:

Step 1. The NRC notifies the contractor, Halliburton NUS, that a utility ,

'ss received : site survey questionnaire, This step requires no action by NSP, and has already been completed.

Step 2. Af ter the utility has received the questionnaire, they will be contacted by Halliburton NUS.

This step was completed during an October 8, 1991 meeting between Region III utilities, NRC Staff and Halliburton NUS where site specific Emergency Response Data System

-implementation issues were~ discussed.

Step 3. A site ylsit will be arranged.

This step was completed during the October 8, 1991 meeting between Region III utilities, NRC and Halliburton NUS.

, At tachnent 1 Page 3 of 4 Step 4. The NRC will Lusta11 phone lines at the site.

Per NRC Generic Letter 91-14, installation of FTS 2000 federal telephone service for Prairie Island is scheduled for February of 1992. NSP will provide the necessary phone connection from the point of entry of the FTS 2000 system to the location of the Emergency Response Data System Jodem.

Step 5. The utility answers and returns th3 site survey questionnaire, containing the Data Point 1.ibrary (DPL) and Plant Attribute Library (PAL) to the NRC.

The Data Point Library and Plant Attribute Library have been completed and are being submitted to the NRC along with this submittal of the Emergency Response Data System implementation program plan. The Data Point Libraries are provided in Attachments 3 and 4, and the Plant Attribute information is included in Attachment 2.

Step 6. If the plant computer requires customized Emergency Response Data System reception software, specific Emergency Response Data System code will be developed and implemented by Halliburton NUS.

The generic Emergency Response Data System software protocols will be used at Prairie Island. Customized Emergency Response Data System reception software will not be required.

Step 7. The utility will design and write the: - data transmission software, The Emergency Response Data System ca.. ractor is developing a PC based ERDS interface which will perform all communication protocol -

functions.

At this time, three options for the implementation of the Emergency Response Data System link at Prairie Island are under consideration. Two of these options utilize the PC based interface being developed by Halliburton NUS, which is expected to be available by April 1992. Our decision on whether or not to use me PC interface developed by Halliburton NUS will be made by the end of November 1991. No matter which of the three options is chosen, work should begin on the design and coding of software for the Emergency Response Data System link on or before December 1991.

a ,

Attachnent i Page 4 of 4 Step 8. Preliminary software testing.

Preliminary software testing will occur during the May to August 1992 time frame, This is the software debugging period for the purpose of identifying and resolving any problems.

Step 9, Following the preliminary software test, a formal test will be conducted at Halliburton NUS, prior to adding the licensee to the Emergency Response Data System.

The Halliburton NUS formal testing can take place any titte af ter the prelittinary testing has been completed. This should occur in the May to August 1992 time frame.

Step 10. A formal test will then be conducted on the Emergency Response Data System computer at the NRC Operations Center.

The NRC Operations Center formal test will occur after successful completica of the Halliburton NUS formal testing and installation into the NRC Emergency Response Data System computer system. These activities .111 be performed and coordinated by the NRC and Halliburton NUS, thus, the schedule is as determined by the NRC and Halliburton NUS.

Step 11. The utility is online, with all development and testing completed.

Upon successful completion of the NRC Operations Center formal test, Prairie Island will be enline and fully integrated into the Emergency Response Data System, a
