! February 26, 1981 Fort St. Vrain i Unit No. 1 P-31070 Mr. Darrel G. Eisenhut, Director Division of Reactor Licensing Office of Nuclear Reactor Regulation U. S. Nuclear Regulatory Commission Washington, D. C. 20555 Docket No. 50-267 I
SUBJECT:
TMI Action Plan Requirements NUREG 0737
Dear Mr. Eisenhut:
In the above referenced letter we indicated M our response to Items III.A.2 that we would provide the details of our meterological system and DCM's for meeting the requirements of NUREG 0654, Appendix 2. The attachT. ant to this letter provides the detailed response and outlines our plans for meeting the guidelines set forth by NUREG 0654 j and the guidance provided in NUREG 0737. I You will note that we cannot have the full four (4) element program in place by April 1, 1981 and in this respect our program is based on the alternatives outlined in NUREG 0737. We are still not in a position to addre',s the schedule dates of NUREG 0737 beyond July 1,1981 as we still do not have NUREG 0696, and we are therefore unable to assess the impact that NUREG 0696 may have on the meterological and DCM systems with reference to the requirements that may be set forth for the emergency response facilities. . Very truly yours,
, h )Y Wwu s,- *)-

< 1 l
t ATTACHMENT 1 P-81070 NUREG 0737 ITEM III.A.2 At the present time the meteorological instrumentation for Fort St. Vrain is mounted on the reactor building and provides the following information to the control room on direct reading recorders and is also provided to the plant data logger. Wind Speed and Direction at 220 feet Temperature at 30' Temperature Differential between 30' and 220' This instrumentation is on the essential bus, but the instrumentation itself was not procured under the provision of Regulatory Guide 1.23. Based on the fact that we do not have a separate meceorological tower or a backup tower our plans for meeting the intent of NUREG's 0654, Appendix 2 and 0737 are as follows:
- 1. We are presently installing a ten (10) meter tower just south of the site. This tower will be instrumented to provide wind speed and disrection, temperature and precipitation and these parameters will be available in the plant data logger system in the control room.
Instrumentation will meet the criteria of Regulatory Guide 1.23. This meteorological station is being installed in conjunction with the National Weather Service and it is our intent to have the system operational on or about April 1, 1981.
- 2. It is our intent on a short term basis to utilize the ten (10) meter tower as our primary tower and utilize the existing instrumentation which is mounted on the reactor building as a backup tcwer. As soon as the 10 meter tower is completed it is our intention to correlate the data from the 10 meter tower with the existing instrumentation presently mounted on the reactor building to ensure that the backup system does in fact provide some reasonable correlation. It should be noted that the 10 meter tower will be served by a completely separate source of power from that which serves the backup instrumentation.
- 3. We are presently procuring replacement wind instrumentation for the existing instrumentation mounted on the reactor building. This wind instrumentation will meet the criteria of Regulatory 1.23. We are anticipating delivery of this replacement instrumentation by April 1, 1981 and would anticipate installation ey May 1, 1981.

- 4. Engineering is in progress for installing a separate 60 meter tower complete with all necessary instrumentation.
4 This tower when completed will replace that instrumentation presently located on the reactor building and will become I the primary tower with the ten (10) meter tower described in Item 1 above becoming the backup tower. Again data from i the new 60 meter tower will be available in the control
; room. We are in the initial design phase for the new , tower, and we are not in a position at the present time to establish a completion date.
i
- 5. By July 1, 1981 we will be prepared to address the above
, systems in more detail with reference to meeting the four (4) element program of NUREG 0654, Appendix 2 by July 1, 1982 and will at that time (July 1,1981) have a detailed schedule for the new 60 meter tower.
J 4
- 6. Per Attachment 2 our DCM for meeting the Class A model requirements has been developed. X/Q plots have been developed utilizing the criteria of Regulatory Guide 1.145.
l These plots permit a determination of X/Q for various 3 stability _ categories utilizing either the 10 meter tower or
! the backup instrumentation (220' level) on the reactor j building. Stability categories will be determined +
utilizing the temperature data . from the backup instrumentation or by calculation utilizing variations in q3 from the 10 meter tower. Our DCM is straight forward. The terrain surrounding Fort i St. Vrain is relatively flat-open terrain and therefore
- there is no need to factor in influences of the terrain or i localized conditions.
- 7. At the present time our DCM has been programuted on a hand i calculator for use in the control room and the Technical Support Center along with the capability of manual j calculations. We are presently in process of putting our
]' DCM on the plant data logger and would anticipate having this model operational on the plant data logger / computer by ! April 15, 1981. By April 15, 1981, then we should have the capability in the control room to make dose calculations on
. the plant data logger, utilize the hand calculator program as a backup or as a last resort make manual calculations.
1- 8. With reference to the compensatory actions outlined in item III.A.2 of NUREG 0737 the following has or will be established: l
AITACHMENT 1 P-81070
- a. We have an agreement with the Nationel Weather Service (NWS) that permits Fort St. Vrain communication with NWS for forecasting information.
These communications will be checked on a monthly basis,
- b. Instrumentation associated with the meteorological measurement program will be calibrated quarterly,
- c. A weekly evaluation of the meteorological measurements program shall be made to ensure availability of data.
- d. Telephone access to meteorological information is available in the Technical Support Center via the NRC hot line, the Health Physics phone or commercial telephone. Dose calculations and meteorological information will be transmitted by voice communications from the Technical Support Center to the Forward Command Post and will be available to Emergency Operations Center (EOC) at Camp George West per established communication procedures outlined in the State and the FSV RERP.
