Mr. Michael F. Weber, Chief Decommissioning and Regulatory Issues Branch Docket No. 50-267

SUBJECT:

FSV Final Survey Plan - Contents of Release Record, Survey Package, and QA Description

Dear Mr. Weber:

l This letter provides additional information regarding documentation of Final Survey efforts at Fort St. Vrain (FSV). This information was requested during an on-site inspection conducted by members of your staff and by representatives of NRC Region IV. Specifically, this letter discusses three items:

l 1.

Definition of the contents of a Release Record; the Release Record is the documentation for each survey area and for the included survey units, that will be submitted as part of the FSV Final Survey Report. A listing of the minimum elements of a Release Record is included as Attachment 1.

2.

Definition of the contents of a Survey Package; the Survey Package includes supporting information for the Release Record, such as raw survey measurement data, and will be maintained as a quality record by Public Service Company of Colorado (PSCo). A listing of the minimum elements of a Survey Package is included as Attachment 2.

i.-

3.

Explanation of a new Quality Assurance (QA) Oversight Report that will be included with each Final Survey Report submittal; this QA Oversight Report will describe PSCo's oversight activities and the third party verification survey activities conducted for PSCo by GPU Nuclear; in 9604230119 960419 PDR ADOCK 05000267 jp w

1 P-96030 April 19,1996 Page 2 addition, NRC inspection activities will be addressed. The QA Oversight Report, while not described in the FSV Final Survey Plan, is intended to provide additional support for Final Survey Report documentation. A more complete description is included as Attachment 3.

If you have any questions regarding this information, please contact Mr. M. H. Holmes at (303) 620-1701.

A1TACHhtENT 1 to P-96030 RELEASE RECORD CONTENTS Release Records provide a summary of survey area information and the survey results that are submitted to the NRC in the Final Survey Report.

Each survey area is documented in a separate Release Record, which includes documentation for each included survey unit. Release Record contents are defined and controlled in Final Survey Procedure FSV-SC-FRS-I-l16, and include at least the following:

Section Comments 1.

Table of Contents Includes SEG and PSCo approval signatures 2.

Survey Area Summary Identifies operational

history, decommissioning and remediation activities, isolation and control

measures, and conclusions regarding the acceptability of the survey area 3.

Survey Unit Summary Identifies survey unit classification and survey design; also documents any investigations or remediation 4.

Maps Simplified sketches of survey unit surfaces, also includes simplified system schematics for piping

systems, showing each measurement location 5.

Statistical Summary Compilation Summarizes statistical data for Total Surface 4

Activity, Removable Surface Activity, and Exposure Rate (except, an Exposure Rate report is not included for piping system surfaces).

Typically includes Upper Confidence

Limit, Mean,

Maximum, Minimum, Standard Deviation, MDA, Critical Level, Samples Reported, and Samples prescribed 6.

Statistical Summary Provides statistical summary for each test performed and data for each measurement type

. -- Relem Record Contents (Continued)

Section Comments 7.

Corrected Field Activity Results of each measurement corrected to 2

Values reporting units (e.g., dpm/100 cm, pR/hr) for each type of measurement.

8.

Graph of Activity vs.

Graphical data summary showing Location Number sample / survey results, guideline value, critical level, MDA, activity / exposure rate, and measurement location number 9.

Summary of Background Identifies values used to correct field Correction Values background values (e.g., PIC corrections) 10.

Summary of MDA Identifies MDA used on each download; also includes critical level and a definition of the medium code used to identify appropriate background 4

11.

Summary of Efficiency Identifies efficiency of each detector used Values (except not applicable to exposure rate) 12.

Detection Equipment Used Identifies instruments and detectors used in the survey i

ATTACHMENT 2 to P-96030 SURVEY PACKAGE CONTENTS Survey Packages provide complete documentation of the survey effort for each survey area, and for the included survey units, from initial package development, through instructions for data collection, raw measurement data, documentation of data analysis, description of any investigations or data replacements, and final review and closure. The Survey Package contains sufficient information to permit calculations to be verified.

Each survey area is defined and documented in a separate Survey Package. Survey Package contents are defined and controlled in Final Survey Procedures FSV-SC-FRS-I-102, for surfaces and structures, and FSV-SC-FRS-I-114, for systems, and include at least the following:

Section Comments 1.

Survey Package Cover Sheet Includes approvals for various package phases Or, For systems, Plant System /

Includes approvals for various package Penetration Survey Package phases Cover Sheet 2.

Initial Survey Package Design Includes initial classification Or, For systems, Initial Plant Includes initial classification; not applicable System Survey Package Design to penetrations 3.

i ATTACHMENT 3 to P-96030 QUALITY ASSURANCE OVERSIGHT REPORT The validity of final survey data is an essential element in the process of terminating the Fort St. Vrain 10 CFR Part 50 license. PSCo, our decommissioning contractor (the Westinghouse Team), and the NRC have all taken strong measures to ensure that the FSV Final Survey Report is a complete and accurate record, providing solid documentation that the FSV facility has been decontaminated to meet the established acceptance criteria.

Quality Assurance / Quality Control (QA/QC) survey activities performed by the Westinghouse Team are documented in the Final Survey Report, as described in the FSV Final Survey Plan. To provide further confidence that the final radiological condition of the FSV site is adequately documented in the Final Survey Report, PSCo intends to document additional QA measures in a QA Oversight Report; this report will be updated and submitted along with each phase of the Final Survey Report.

The QA Oversight Report will describe PSCo's principal QA oversight activities, including the following:

Audits Surveillances and/or monitorings of ongoing survey activities Review of procedures and technical basis documents Review of Release Records and supporting survey packages Verification of calculated measurement results Third party verification survey activities performed for PSCo by GPU Nuclear NRC inspection activities and PSCo's responses to any identified findings Problem Reports, corrective actions, and resolutions of deficiencies i
