SUBJECT:

Revised Contents of Final Survey Release Records and Survey Packages

REFERENCES:

1. PSCo Letter, Borst to Weber, dated April 19,1996 (P-96030)

2. PSCo Letter, Borst to Weber, dated August 2,1996 (P-96064)

Dear Mr. Weber:

This letter provides a revision to Public Service Company of Colorado's (PSCo) definitions of the contents of documentation packages associated with the Fort St. Vrain final survey project. In Reference 1, PSCo listed the minimum elements of both the Release Record, which will be submitted as part of the Final Survey Report, and of the Survey Package, which includes supporting information and will be maintained by PSCo as a quality record.

During performance of the Fort St. Vrain final survey efforts, four changes to the documentation plans were made.

• The referenced letter states that each survey area is documented in a separate Survey Package. In some cases, survey areas were divided into more than one Survey Package, to simplify the survey effort and allow for more manageable document reviews. The definitions for both Survey Packages and Release Records are revised to state that each survey area is documented in one or more separate Survey Packages. The same revision is also made for Release Records.

• The referenced letter indicates that initial classification information is i provided in the Initial Survey Package Design section of the Survey j Packages. This information regarding initial classification is actually a contained in the Survey Area History File included in the Survey l Packr.ges.

• The referenced letter indicates that Survey Packages include a Survey I i Download Data Form. Information on this one-page form was contained in other locations in the Survey Packages and the form was deleted from j the Survey Package contents for simplification. l i

• The referenced letter indicates that Release Record contents include a l l Survey Area Summary and a Survey Unit Summary. Release Records do  !

contain these sections, however the titles are actually " Release Record - I

Survey Area" and " Release Record - Survey Unit," respectively. '

l  !

The definitions of Release Record contents and Survey Package contents, originally l 4

provided with Reference 1, have been revised to reflect the above changes and are

! attached to this letter. The attachment also reflects a change previously identified in

! Reference 2, wherein Release Records only include one applicable MDA, critical level,  ;

} efficiency, and background value for removable surface activity measurements.

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

• I ATTACHMENT 1 to P-96083-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 one or more separate Release Records, which include documentation for each included survey unit. Release Record contents are defined and controlled in Final Survey Procedures and include at least the following:

Section Comments 1

1. Table of Contents Includes SEG and PSCo approval signatures

2. Release Record - Survey Identifies operational history, Area decommissioning and remediation activities, isolation and control measures, and conclusions regarding the acceptability of the survey area

3. Release Record - Survey Identifies survey unit classification Unit and survey design; also documents any  ;

investigations or remediation 1

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

4 Attachment 1 -- Relenca Record Contents (Continued)

Section - Comments

7. Corrected Field Activity Results of each measurement corrected to Values reporting units (e.g., dpm/100 cm 2

, R/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 1

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; for removable surface activity measurements, only one applicable MDA, critical level, and background value is included

11. Summary of Efficiency Identifies efficiency of each detector used Values (except not applicable to exposure rate); for removable surface activity measurements, only one applicable efficiency value is included

12. Detection Equipment Used Identifies instruments and detectors used in the survey

SURVEY PACKAGE CONTENTS l

l Survey Packages provide complete documentation of the survey effort for each survey l area or survey unit, as applicable, from initial package development, through instructions  !

for data collection, raw measurement data, documentation of data analysis, description I 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 dermed and documented in one or more separate Survey Packages. Survey Package contents are defined and controlled in Final Survey Procedures and include at least the following:

Section Cornments

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

2. Initial Survey Package Design includes survey measurement plans Or, For systems, Initial Final Includes survey measurement plans; not Survey Design for Plant Systems applicable to penetrations
