SUBJECT:
NUREG-0737, Item III.A.2,-
Meteorological Monitoring System Peach Bottom Atomic Power-Station
Dear Mr. Eisenhut:
This letter provides most of the additional information promised in a December 23, 1982 letter (3. L. Daltroff to D. G.
Eisenhut) regarding implementation of a new meteorological monitoring system for the Peach Bottom Atomic Power Station.
The remaining information will be provided by April 15, 1983 in accordance with the new NRC scheduling requirements established in Generic Letter No. 82-33, Supplement 1 to NUREG-0737,
' Requirements for Emergency Response Capability, dated vecember 17, 1982.
As stated in Generic Letter No. 82-33, the requirements in the enclosure to that letter supersede the
-requirements in the affected NUREG-0737 items.
In lieu of
-stating a specific implementation schedule for the meteorological
. monitoring system, the NRC letter states that each licensee should deve3op and submit its own plant specific schedule no later than April ~ 15, 1983, which will be reviewed by the assigned NRC Project Manager.
The Project Manager and licensee will Subsequently reach an agreement on the final schedule as quickly as possible.
This letter describes the current status of our efforts to complete the upgraded meteorological monitoring system and identifies our plans for proposing a schedule by April 15, 1983 as requested by Generic Letter 82-33.

Mr. Darrell G. Eisenhut, Director Page 2
The meteorological monitoring system at Peach Bottom is-being modified to comoly with Regulatory Guide 1.23, Proposed Rev~_1 and NUREG-0654 criteria.. A descript'_on of theLupgraded
- system:vas provided in correspondence. dated _May 6, 1982 (S.
L.
.Daltroff to D. G. Eisenhut). ' The upgraded system is expected to be installed as described, except as~noted;below, by the end of
' February,'1983.
However,.the. conversion'to the upgraded system willl require-a transition period to write procedures and_ train emergency response personnel.
Development of new procedures will commencoEin late February after the back-up manual calculation methodology ~is upgraded to provide results consistent with the computer dose model.
Personnel are currently trained to calculate off-site doses manually'using the present instrumentation land methodology.
Extensive training will be required before.the new system can be considered operational.
The plans for the-procedures and training will_be reviewed with the NRC Project Manager and~identifi'ed in an April 15, 1983 submittal'in accordance with Generic Letter 82-33.
Most-of the upgraded _ meteorological monitoring system J
har'dware has been'~ installed and data is currently displayed in the main control room.
The system software to provide-full meteorological data availability in the Emergency' Operations
- Facility, and to permit remote interrogation of data by government agencies is expected to be' completed by the end of February 1983.
The only portions of the system described in the
'May 6, 1982 letter that will not be completed by February 1983 are as follows:
1.
.The wind instrumentation at the 30 feet elevation on tower No.2.
- 2.
The dew point sensor on tower No. 2 3.
The primary weather tower (tower no. 2) wir-3 instrumentation at the 75 feet and 320 feet elevations will be accurate to within i 1.0 mph (greater than 10 mph) vs. a required accuracy of i 0.5 mph for all speeds per Regulatory Guide 1.23, Proposed Rev. 1.
In addition, the starting wind speed for this instrumentation will be 1.8 mph vs.
the Regulatory Guide 1.23 requirement of 1.0 mph.
4.
The dose model on the on-site computer.

.The~ delay.ini-upgrading:the-instrumentation on tower No.
, 2 is due to~ structural-. deficiencies in the~ tower discovered during,Lthe' installation of~new. equipment.
An. engineering evaluation of the: tower's structural capabilities.to identify the 3necessary corrective action willlbe' completed within several-weeks.=-In the absenceJof the on-site computer, the deae model/is n
presently. installed on -the corporate l computer-and is accessed tar terminal from.the Peach Bottom EOF, and therefore-meets the intent of NUREG-0737, Item II.A.2.2.
- A schedule for completing cLinstallation offthe on-site computer, and' installing new
' instrumentation onLtower No.: 2 to comply with our previous
~
Lcommitment.of-May.6, 1982 will~be identified by April 15, 1983 in Laccordance with Generic Letter 82-33.
Should you have any-questions concerning~this matter,
'please do not hesitate-to contact us.
