RESPONSE TO NRC QUESTIONS HOPE CREEK EMERGENCY PLAN METEOROLOGY HOPE CREEK GENERATING STATION DOCKET NO. 50-354 The attached information is provided in response to your request for additional information dated February 9, 1984, regarding emergency plan meteorology. This response addresses the four (4) items identified in that letter.

Correspondence transmitted to the NRC under a' separate docket is being incorporated by reference per 10 CFR 50, Part 32 in response to Items 2 and 3. This information was submitted to the NRC pursuant to the Salem Nuclear Gen-erating Station Unit No. 2 (Docket 50-311) Operating Licens-ing requirements, Item 24.d.ii and 24.d.iii (letter dated May 20, 1981). A letter to Frank J. Miraglia from R. L. Mittl dated July 30, 1981,. responded to Item 24.d.ii.

A letter to Frank J. Miraglia from R. L. Mittl dated June 30, 1981, responded to Item 24.d.iii.

The Emergency Plan will be amended to incorporate the responses to Items 1 and 4.

Should you have any questions in this regard, do not hesi-tate to contact us.

Very truly yours, j $ f/ ,

. RESPONSES TO EMERGENCY PLAN QUESTIONS DATED FEBRUARY 9, 1984 Question No. 1 A complete description of the back-up meteorological system at the local oil refinery, in the event the applicant uses meteorological data from this source.

Response

A decision was made by Public Service after discussion with the staff of the indicated oil refinery that it would be impractical for Public Service to use this data as a back-up source. Back-up meteorological data is provided by a back-up tower located on site approximately 500 ft. south of the primary meteorological monitoring tower. Back-up meteorological data is provided by wind speed and wind direct sensors mounted on a ten meter telephone pole. In addition to the 15 minute averaged wind speed and wind direction, a computed sigma theta value is provided. The primary, as well as the back-up meteorological information will be available in the Hope Creek Main Control Room, Hope Creek TSC and the EOF. The Hope Creek Emergency Plan will be amended to discuss onsite back-up meteorological data. Additional back-up data is available from the Wilmington, Delawarc NOAA Weather Station.

Question No. 2 The bases for determining the representativeness of the back-up source at the Wilmington, Delaware NOAA Weather Station.

Response

The emergency plan for Hope Creek provides for meteorological data to be supplied from the National Weather Station located at the Wilmington Airport, 15 miles north-northwest of the site.

A complete discussion of the representativeness of this back-up source was presented to the NRC in a letter to Frank J. Miraglia from R. L. Mitti dated June 30, 1981, Salem Nuclear Generating St.-tion Unit 2, Docket No. 50-311. This information is incorp-orated by reference. Additional discussion of the representa-tiveness of the Wilmington data is presented in Section 2.3 of the FSAR.

3 Question No. 3 Sufficient description of the atmospheric models to be used such that the staff can determine whether PSE&G is progressing toward an acceptable use of meteorological information in emergency response.

Paga 2 of 2

Response

The Artificial Island Meteorological Monitoring System has been upgraded with a digital, remote access computer system.

The functional description of the upgraded Meteorological Monitoring System was transmitted to the NRC in a letter to Frank J. Miraglia from R. L. Mitti dated July 30, 1981, Salem Nuclear Generating Station Unit 2, Docket No. 50-311.

This information is incorporated by reference. The system described in this functional system has been installed and is in the process of being made available for emergency planning purposes. The system is designated as the Artificial Island Meteorological Monitoring System and will serve Hope Creek as well.

The Hope Creek Padiation Monitoring System (Central Radia-tion Ptocessor - CRP) provides meteorological data output.

The Hope Creek Radiation Monitoring System provides for route radiation dose assessment. A system enhancement to include emergency dose assessment is underway and a description will be provided by December 1984. The Hope Cteek Radiation Monitoring System design provides 15 minute average metectological data for wind speed, wind-direction, delta temperature, and sigma theta.

Question No. 4 The emergency plan should identify the FSAR, Section 2.3.3, as a cross reference for a complete description of the meteorological system.

Response

The Hope Creek Emergency Plan will be amended to include this teference to the Hope Creek FSAR.
