ATTACHMENT I Responses to ORISE Recommendations Recommendation 1: "SNEC calculations E900-03-003 (Appendix A, GPU 2003) and 6900-02-024 (Appendix B, GPU 2003) were reviewed. To address the concern stated in Appendix A, Section 4.1 1, that uCompass (version 1.0) does not perform well when using the gross activity option" and to make the section calculations more straightforward, ESSAP recommends the following changes to the document text and COMPASS data entry.
Create a table that shows the contaminants of concern and associated radionuclide mixture fractions.
Each row would also include the instrument, surface, and subtotal total efficiencies. The summation of the subtotal total efficiency column will be the desired total efficiency value. Note that the fraction column must sum to one, and in the COMPASS software the gross activity DCGLw conversion from dpm/100 cm2 to cpm cannot be performed unless this condition exists. With this format, the reviewer can easily determine the parameters used to calculate the total efficiency. This change would have no impact on the final result, but should make the process easier to implement for future calculations when more than one radionuclide is detectable for a gross activity measurement."
Response:        A table will be included, as applicable, into future FSS reports listing the representative radionuclide mixtures in the survey unit(s) and how the corresponding efficiencies were determined. These efficiencies will include the instrument and surface parameters to determine total efficiency.
Recommendation 2: "SNEC calculations E900-03-003 and 6900-02-024 were reviewed. Scan and static MDC determinations were consistent with guidance and were calculated to be less than 50% of the DCGLw. However, for calculation E900-03-003, sections 4.15 and 4.16, the incorrect background value was used in the MDC calculations. The correct value to use would be the unshielded (or open window) background average from the survey unit because the scan survey was performed with an unshielded detector. These errors would not affect the conclusions of the final status survey."
Response:        Future designs and FSS reports will use the unshielded background readings that are applicable to the type of survey and survey unit area.
Recommendation 3: "SNEC calculations E900-03-003 and 6900-02-024 were reviewed. No concerns were identified with the selection of the background reference area. Background contributions were accounted for during survey planning, but not during data assessment.
Because survey unit gross activity levels were less than the DCGLw, use of the background reference area data in the application of the WRS Test was not required (see Comment 4, Attachment A)."
Response:        Exhibit 2 of this letter lists the ORISE comments that were made to SNEC's draft FSS report. These comments were listed in Reference 1, Attachment A. These comments are also listed in Attachment 2 of this letter for clarification. Note response to Comment 4.
 
Attachment 2 Additional Comments (From Attachment A of ORISE Report)
: 1) Executive Summary, Page 1, Paragraph 2: ESSAP recommends defining the purpose of the removable activity supplemental data. See Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) section 8.5.3.
Response:        Comment included into revised report (see Attachment 3).
: 2) Executive Summary, Page 1, Paragraph 2: ESSAP recommends that the exposure rate measurements performed be mentioned in this section as also being 'supplemental" in nature.
Response:        Comment included into revised report (see Attachment 3).
: 3) Section 3.1.1.2: This section states that all static measurement results were less than 250 net cpm-the action level for scanning per calculation 6900-02-024. First, the action level should be changed to 580 net cpm for direct measurement comparison to the DCGLw. This change should also occur in sections 3.1.2.2, 3.1.3.2, and 3.1.4.2.
Response:        Comment included into revised report (see Attachment 3).
: 4) Section 3.1.1.2: The table included in this section shows data for shielded and unshielded measurements with the net cpm difference calculated. As written, the data assessment appears to compare the net difference column to the DCGLw, which is not consistent with MARSSIM guidance for data assessment when using the WRS Test. The last sentence in the section should be rewritten to discuss only the unshielded (gross) measurement results and how they compare to the DCGLw. The shielded and net difference columns should be removed from the table. These suggestions also apply to the remaining sections titled 'Static Measurements." Per calculation E900-03-003, section 4.14, shielded measurements were performed to correct background reference area ambient values to be consistent with the survey unit. Once the reference area measurements are corrected for the difference in the survey unit and reference area ambient backgrounds, additional shielded measurements are not required and including additional shielded measurement data could be confusing to the reader.
Response:        Comment included into revised report (see Attachment 3).
: 5) Sections 3.1.1.2 and 3.1.1.3: ESSAP recommends that the discussions in these sections should be reversed in order because QC smears are discussed before the smear survey results are discussed. This recommendation would apply to many sections throughout the document.
Response:        Comment included into revised report (see Attachment 3).
: 6) Section 3.1.5: ESSAP recommends adding a discussion of how the gamma spectroscopy data from the smears should be interpreted.
Response:        Comment included into revised report (see Attachment 3).
: 7) Section 3.5, Table: ESSAP recommends reporting the actual value of each gamma spectroscopy measurement, with the minimum detectable concentration (MDC) reported using a standard background for the process or individually for each measurement.
Response:        GPU Nuclear and NRC agreed that current reporting convention is satisfactory. This convention will continue to report the MDC value and not the net value for gamma spectroscopy measurements.
: 8) Section 5.0, Paragraph 5: ESSAP suggests rewording the summary written as "be backfilled to at least the 774' elevation' to clarify that the containment vessel (CV) will be backfilled no higher than the 774' elevation.
Response:        Comment included into revised report (see Attachment 3).

Executive Summary This report presents the results and conclusions of the final status survey (FSS) conducted by GPU Nuclear, Inc. of the bottom interior of the Saxton Nuclear Experimental Corporation (SNEC) Containment Vessel (CV). This FSS specifically includes the results of structure surface measurements taken in the CV interior 774' elevation and areas below. The FSS for this area was started in March 2003 and completed in April 2003.
The FSS was performed in accordance with Revision 2 of the SNEC License Termination Plan (LTP). The CV structure surfaces were divided into eight (8) Class 1 survey units. Each survey unit was comprised of building structure surfaces and metal plates varying in shape and size.
Survey data was collected from each survey unit according to data collection requirements specified in the FSS design criteria. The following types of measurements were performed:
: 1. Scan measurements were performed over 337 m2 (100% of all accessible survey unit surface areas).
: 2.      92 static measurements were collected as final survey data.
: 3.      In addition, 44 supplemental removable surface radioactivity measurements were collected. Although smear results are reported they are not used for determining compliance but for adherence to LTP section 6.2.1. Instead, they are used as a diagnostic tool to determine if the removable surface radioactivity is less than 10% of the surface area DCGL,.
: 4.      Exposure rate measurements (uR/hr) were performed. These are considered supplemental in nature and was used as a point of comparison with past release criteria.
The. collected FSS data demonstrate that each survey unit meets the radiological criteria for i~f unrestricted use specified in 10 CFR 20.1402. Based on the results of the CV final status survey, GPU Nuclear, Inc. concludes the CV interior 774' elevation and below meets the NRC requirements for release to unrestricted use.

==1.0    Purpose and Scope==
 
This report presents the results and conclusions of the final status survey of the SNEC Containment Vessel Interior 774' and areas below this elevation. It provides the information required by 10 CFR 50.82(a)(1 1) and SNEC's License Termination Plan (LTP) to demonstrate that this area meets the radiological criteria for unrestricted use specified in 10 CFR 20.1402.
This report describes the radiological data collected for eight (8) Class I survey units contained within the SNEC CV lower head area. SNEC personnel have decontaminated seven (7) of these survey units. Survey unit, CV2-23, (a steel support ring) was installed new to the CV to add structural stability to the building during the concrete removal project.
This report only addresses the final status survey performed on the interior structure surfaces located at and below the CV 774' elevation. Interior areas above 774' are not addressed in this report. The format of this report follows the guidance contained in Reference 6.13.

2.0    Final Status Survey Deslan for CV 774' and Areas Below 2.1 Description of Survey Units The eight (8) survey units are listed below. These survey units are all designated as Class 1.
The survey unit codes were taken from Table 5-2, of SNEC LTP Revision 2. These survey units are: CV2-19, CV2-20, CV2-21, CV2-22, CV2-23, CV3-1, CV3-2 and CV3-3.
Survey unit designations CV2 CV2-22 comprises the CV shell surface area to which the steel support ring is welded. These survey units consist of a 3600 annular area around the CV interior shell and are located directly behind the welded steel support ring. These survey units consist of four (4) quadrant regions, (Quadrants A-D), each approximately 3.04 m (12.2 m2 total).
Survey unit designation CV2-23, is a W14 x 74 W-beam support ring (centered at the 774'-
9' elev.) that was welded to the CV shell to stiffen this structure after CV concrete removal.
The W-beam did not have residual surface activity at the time of installation. Additionally, a small section of the D-plates, which make up the vertical section of the CV steel shell structure, is Included. This area is -5' high and is located just below the W-beam. The W-beam extends 360 degrees around the Inner circumference of the CV shell. The total area of this survey unit is 74.5 m2, which includes the beam and the area just below the beam.
Survey unit designation QYV.I is composed of ten (10) C-Plates (Cl through C10), starting at about the 773'-8" elev. just below the W-beam area, and extending down to the top of the B-plates. This survey unit is approximately 104.9 of in total area.
Survey unit designation CV3-2 is composed of sixteen (16) B-Plates starting at about the 767' elev. and extending down near the base of the CV shell at the 760'-7" elev. This survey unit is approximately 124.4 m 2 in total area.
Survey unit designation CV3-3 is composed of two (2) A-Plates that form the bottom of the SNEC CV shell. This survey unit is approximately 21.1 m2 In total area.
2.2 Remediation History Remediation of the SNEC CV began with gross decontamination and equipment removal, e.g. piping, steam generator, pressurizer and the reactor vessel (fall of 1998). Failed attempts to decontaminate the concrete inside the CV structure resulted in a decision to completely remove the concrete from the building. In order to accomplish this, a ground water abatement system around the exterior of the CV was installed. By the fall of 2002 the SNEC CV internal concrete structure was completely removed. However, several external and internal stiffener rings were necessary to maintain structural integrity and to prevent buckling of the building. These rings were welded to the steel shell to add rigidity and produce a safe working environment for remediation crews and survey personnel. The internal surface of the CV steel shell was then cleaned to remove radiological contamination, paint, residual concrete dirt, weld and surface scale. Original weld areas between the sections of steel plate that make up the steel shell were decontaminated along with prominent surface defects. Remediation efforts of the interior CV steel surface included combinations of the following techniques:
* Roto-peening
* Liquid paint remover (MIRACHEM)
* Surface grinding 3
* Needle gun
* Grit blasting
* Wire brush
* Vacuuming
* Surface wipe-down A decontamination effectiveness check was performed during the cleaning effort by means of biased and unbiased measurements on the surface of the cleaned steel shell using a gas flow proportional counter (GFPC). The criteria for determining when an area was acceptably decontaminated was initially established at < 3 times the local background count rate as determined by closed window readings in the area. Areas above this value were re-ceaned.
A post remediation survey was conducted which included both surface scans and static measurements. It also included a surface smear survey and sampling of the steel surface in one suspect activation region. It was later determined that the suspect region was not activated. Alpha radiation measurements were also taken at select locations. Smears were counted for both beta-gamma and alpha contamination.
2.3    Site Release Criteria The site release criteria applied to the CV interior correspond to the radiological dose criteria for unrestricted use per 10 CFR 20.1402. The dose criteria is met &#xb6;f the residual radioactivity that is distinguishable from background radiation results in a Total Effective Dose Equivalent (TEDE) to an average member of the critical group that does not exceed 25 mrem/yr, including that from groundwater sources of drinking water, and that the residual radioactivity has been reduced to levels that are as low as reasonably achievable (ALARA)."
Levels of residual radioactivity that correspond to the allowable dose to meet the site or survey unit release criteria were derived by analyses using the building occupancy scenario (e.g. direct radiation, inhalation and ingestion). The dose modeling for this scenario is explained in the SNEC LTP, Revision 2, Section 6.2.1. The derived concentration guideline levels (DCGLs) form the basis for satisfying the site release criteria.
Residual radioactivity sample results for non-activated surfaces inside the CV were compared to calculate gross activity DCGLs. These gross activity DCGLs were developed using the methodology described in SNEC LTP Section 5.2.3.2.4, based on radionuclide specific DCGLs listed in Table 5-1 of the LTP. Gross activity DCGLs were not applied to areas or materials containing volumetric residual radioactivity.
A correction to the gross activity DCGLw was made to address de-isted radionuclides and to correct for activated steel in the SNEC CV. The SNEC facility has instituted an administrative limit of 75% for the allowable dose (DCGL) for all measurement results. The de-isted radionuclide dose is accounted for within the 75% administrative limit, but the activated steel dose correction is not. Based on Microshield calculations for activated metal inside the CV, an additional 28.8% reduction was also made for measurements taken in these regions. These correction factors are reported in the SNEC LTP, Chapter 6.
2A Survey Designs Survey unit designs are provided in Appendix A and B. Since all the survey units are Class 1 scan measurements were performed over 100% of the surfaces. The number of static measurement points was determined using the COMPASS computer program (Reference 6.3). These points were located on survey maps for each survey unit using the VSP, Visual Sample Plan (Reference 6.4) computer code.

Survey designs use a gross activity DCGLw value developed for these survey units from scrape samples of the interior surface of the SNEC CV. These samples were taken at five (5) different elevations In the CV. The sample result that produced the most conservative effective DCGLw value was then used as input to the Compass computer program. The nearest sample result to the lower head region was taken from the 774' elevation of the CV.
However, scrape samples of surface contaminants have been collected from other internal CV shell support ring installation areas. These scrape samples consist largely of paint and concrete residual along with surface scale.
Cs-137, H-3 and Ni-63 account for the majority of radionuclides. Cs-137 is the predominate radionuclide and provides the only reasonably detectable radionuclide in this mix.
The following table presents the data quality objectives (D1Os) and other relevant information, which went Into the survey design packages.

3.0    Final Status Survey Results The following sections provide the survey summary results for each survey unit as required by the respective design. Summary data was taken from References 6.7 - 6.12 which are filed in the SNEC FSS history file.
3.1      Survey Units CV2-19, 20,21,22, "Interior CV Weld Ring Areas @ 774 ft El" These surveys were performed on the CV steel liner, approximately 774' elevation, prior to the installation of an internal support ring. Surface scan and static measurements were performed using a Ludlum 2350-1 6 datalogger" system. The metal surface area that was surveyed consisted of a single band measuring 10 inches wide and spans the circumference of the CV liner. The band was divided into four equal quadrants; namely Am, ABE, *C*, and OD'. Each quadrant was a separate survey unit These survey units were designated as CV2-19, CV2-20, CV2-21 and CV-22.
Prior to the survey static unshielded and shielded GFPC (gas-flow proportional counter) surface measurements were performed to determine an estimate for the mean and sigma of each survey unit. This calculation was documented in Calculation No. 6900 024 (See Appendix B).
The scan speed was set at 2.2 cm/second (1 detector width per 4 seconds). The effective DCGLw for this measurement plan is taken to be 2100 drm/100 cm2 . A net fixed point measurement result of about 580 cpm yields -2100 dpml100 cm2 (the DCGLw) for a 1 minute count time.
No WRS statistical analysis is necessary for this survey unit since all resulting static measurements are below the assigned DCGLw (580 net cpm per 100 cm2 or 2100 dpml1 00 cm2).
Although the survey unit is ten inches wide, an additional four inches of shell has been cleaned above and below this region. Surface scan measurements included this additional area. It must be noted that some static measurements were made in this buffer region when the required survey point fell on the outside boundaries of the survey unit.
3.1.1    Summary of Results for Survey Unit "CV 2-19" (Quadrant "A")
3.1.1.1 Surface Scan Measurements After establishing an average background (ABCR) for the survey (166 cpm), a 100%
surface scan was performed using a Ludlum-2350-1 with a 43-68B probe. The action level was >250 ncpm. All measurement results indicated <250 ncpm.

Five smears were taken in the quadrant. Since no elevated activity was detected during the scan and static survey measurements additional smears were not warranted. Smear results indicated <1 K dpm/1 00 cm2 beta-gamma and <MDC (11 .6 dpm/1 00 cm2 ) alpha.
3.1.1 A Quality Control (QC) Measurements A 5% re-sampling and re-survey requirement was performed. Scan measurements were performed in a four foot section between fixed points #2 and #3 to verify initial scan measurements were <250 ncpm. Measurement results were <250 ncpm. This re-survey area is approximately 10% of the total quadrant area.
A static measurement set was re-performed on survey point #5. Measurement results indicated a net difference <250 cpm.
A smear was taken at smear location #3. Smear results indicated <1K dpm/100 cm 2 beta-gamma and <MDC (11.6 dpm/100 cm 2) alpha.

3.2.1.4 Loose Surface Contamination (Smear Survey)
Three smears were taken as part of a post remediation survey. Since no elevated activity was detected during scan and static survey measurements additional smears were not warranted. Results from the three smears indicated <1K dpmi/100 cm2 beta-gamma and <MDC 13.1 dpml100 cm2 alpha. Also see section 3.6 for smear results.
3.2.1.5 Quality Control (QC) Measurements and Comparisons Scan measurements were performed on approximately 6.6 m2 (8.8% of the total survey unit surface area). Measurement results were <200 NCPM. This percentage meets the 5% requirement. Static measurements were obtained for points #3 and #17.
Measurement results were <400 NCPM. This percentage, 2 of 20 (10%), meets the 5%
requirement Static Measurement (Micro-Rem) was performed in the vicinity of the initial survey point location in OCO Quadrant. This percentage, I of 8 equals 12.5%, meets the 5%
requirement 3.2.1.6 Exceptions & Discrepancies Static measurement point # 20 was re-located as per the survey designer. Initial location coordinates fell outside the survey unit.
Scan surveys could not be performed on some ring surfaces. These exceptions were due to ring support obstructions, connection joints and 90&deg; bends in the ring. All areas not surveyed were noted on the documented surveys located in the SNEC history file.
All areas not surveyed consisted of clean material installed during concrete demolition.
Areas of joints between rings were originally sealed and maintained in an isolation condition. Additionally, the combined surface area of these unsurveyed areas is insignificant when compared to the total survey unit area, (0.23 m2 of 74.5 m2 equals 0.3%). Since the adjacent exposed surface areas were found to be less than the action level it is concluded that these inaccessible and protected areas are also less than the action level.

4.0    Data Assessment The final status survey data has been reviewed to verify authenticity, appropriate documentation, and technically acceptable. The review criteria for data acceptability are:
: 1. The instruments used to collect the data were capable of detecting the radiation of interest at or below the investigation level.
: 2. The calibration of the instruments used to collect the data was current and radioactive sources used for calibration were traceable to recognized standards or calibration organizations.
: 3. Instrument response was checked before and, where required, after instrument use each day data was collected.
: 4. Survey team personnel were properly trained in the applicable survey techniques, and this training was documented.
: 5. The MDCs and the assumptions used to develop them were appropriate for the instruments and the survey methods used to collect the data.
: 6. The survey methods used to collect the data were appropriate for the media and types of radiation being measured.
: 7. Special measurement methods used to collect data were applied as warranted by survey conditions, and were documented in accordance with an approved site Survey Request procedure.
: 8. The custody of samples that were sent for off-site laboratory analysis, were tracked from the point of collection until the final results were obtained, and
: 9. The final status survey data consists of qualified measurement results representative of current facility status were collected in accordance with the applicable survey design package.
If a discrepancy existed where one or more criteria were not met, the discrepancy was reviewed and corrective actions taken (as appropriate) in accordance with site procedures.
The statistical test does not need to be performed for this final status survey since the data clearly show that the survey unit meets the site release criteria. The survey unit clearly meets the criterion because of the following:
: 1. All measurements in the survey units are less than or equal to the DCGLw, or
: 2. A background reference area was used and the difference between the maximum survey unit measurement and the minimum background reference area measurement is less than or equal to the DCGL.
21
 
6.0    Final Survey Conclusions The CV Interior, 774' EL and below final status survey was performed in accordance with Revision 2 of the SNEC LUP and site implementing procedures. Final status survey data was collected to meet and/or exceed the quantity and quality specified for each survey unit as prescribed by the applicable survey design. The survey data for each survey unit met the following conditions:
: 1.      The average residual radioactivity inside the lower CV was less than the assigned DCGLW.
: 2.        Since all measurements were less than the DCGL, no EMC DCGL criteria needed to be applied.
: 3.      Remediation was performed to reduce the levels of residual radioactivity to below the concentrations necessary to meet the DCGLs.
These conditions satisfy the release criteria established in the SNEC LIP and the radiological criteria for unrestricted use given in 10 CFR 20.1402. Therefore, it is concluded that the SNEC CV Interior, 774' El. and below is suitable for unrestricted release and can therefore, be backfilled no higher than the 774' elevation.

CV Interior, 774' EL and Below, FSS Survey Design 1.0 PURPOSE 1.1      The purpose of this calculation is to develop a survey design for four (4) Class 1 survey units contained within the SNEC CV lower head area. Three of these survey units have been aggressively decontaminated by SNEC personnel using methods described in section 4.8. The fourth survey unit (a steel support ring), was installed new to the CV to add structural stability to the building during the internal concrete removal project.
1.2      The four (4) survey units are composed of the items shown on Attachment 1-1 (from Reference 3.1), through 1-4 (and are listed below). The Location Codes" (taken from Table 5-2, of Reference 3.2) for these survey units are: CV2-23, CV3-1, CV3-2 and CV3-3.
1.3      Survey unit designation CV2-23, is one W14 x 74 W-beam support ring (centered at the 774'-9 El) that was welded to the CV shell to stiffen this structure after CV concrete removal. The area under the W-beam was surveyed lAW an "at risk' survey design (FirstEnergylGPU Calculation No. 6900-02-024, Reference 3.3). The W-beam was a radiologically clean member at the time of installation. Additionally, a small section of the D-plates, which make up the vertical section of the CV steel shell structure, is included. This area is -5" high and is located just below the W-beam. The W-beam extends 360 degrees around the inner circumference of the CV shell. The total area includes the beam and the area just below the beam which form one survey unit of approximately 74.5 square meters.
1.3.1    Survey unit designation CV-1, is composed of 10 C-Plates (Cl through C10),
starting at about the 773'48 El just below the W-beam area, and extending down to the top of the B-plates. This survey unit is approximately 104.9 square meters in total area.
1.3.2 Survey unit designation CV-2, The 16 B-Plates start at about the 767' El and extend down near the base of the CV shell at the 760'-7' El. This survey unit is approximately 124.4 square meters in total area.
1.3.3 Survey unit designation CV3-, The 2 A-Plates form the bottom of the SNEC CV shell. This survey unit is approximately 26.3 square meters in total area.
1.4    This calculation also establishes a working gross activity DCGLw (in dpml100 cm2) for these survey units.

CV Interior, 774' EL. and Below, FSS Survey Design 4.4      The number of points chosen by Compass was located on survey maps for each survey unit by using the Visual Sample Plan (VSP) computer code (Reference 3.6).
4.5      VSP is used to plot random start systematically spaced fixed point survey locations on diagrams used in the field by survey personnel. The coordinates of the survey points are provided for each survey unit. Because of edge effects and a desire to error on the conservative side, additional measurement points have been forced by increasing the overage from the required 20% to as much as 100% for one case. This was done to ensure that at least one measurement point was located within each CV structural plate, and that a significant frequency of point placements were attained along the structural support beam.
The result is that the bounded regions are less then that calculated by Compass which indicated that 8 survey points -were adequate for each survey unit. In the case of the support ring, the four quadrants were stacked in pairs graphically before plotting out the survey points. The triangular grid was split between two ring sections resulting in differing vertical point placements along each quadrants.
4.6        Reference 3.6 was used as guidance during the survey design development phase.
4.7      The construction/assembly drawings used to determine the physical extent of these areas are listed as Reference 3.1, 3.7, and 3.8. In addition, Reference 3.9 was used to establish the surface area of a steel W-beam (see Attachment 1-3):
* Flange thickness is 0.783" (4 areas of exposed thickness are considered). Then 4 x 0.783" = 3.132".
* Top width of Flange area is 10.072 wide.
* Bottom Flange area is welded to CV.
* Four areas of exposed Flange are located adjacent to the Web. Then 4 x 4.811" =
19.244".
* Height of Web is taken to be 14.19 - (2 x 0.783') = 12.624" x 2 = 25.248".
* Then the total vertical section is: 3.132m + 10.072" + 19.244" + 25.248" = 57.696" Adding the lower 5"section of D-plates yields 57.696" + 5" = 62.696" The circumference of the CV is 50 ft x 12fft x s = 1885" which is at the welded area of the W-beam (at the surface of the CV). However, since the W-beam is 14.19" in height, the exposed top Flange area of the W-beam is only [(50 ft x 12"/ft) - (2 x 14.19")] x lr= 1796" in circumference.
4.8      Remediation History Remediation of the SNEC CV began with gross decontamination and equipment removal e.g., piping, the steam generator, the pressurizer and the reactor vessel (fall of 1998).
Extensive attempts at clean-up of the internal concrete structure indicated that the concrete had to be removed from the facility. In order to accomplish this, ground water abatement around the exterior of the CV was necessary and established. By the fall of 2002 the SNEC CV internal concrete structure was removed in total. However, several external and internal stiffener rings were necessary to maintain structural integrity. These assemblies were welded to the steel shell to add rigidity and produce a safe working environment for remediation crews and survey personnel. The internal surface of the CV steel shell was

Original weld areas between the sections of steel plate that make up the steel shell were vigorously decontaminated along with apparent surface defects.
Remediation efforts of the interior CV steel surface included combinations of the following techniques:
* roto-peening
* liquid paint remover (MIRACHEM)
* surface grinding
* needle gun
* grit blasting
* wire brush
* vacuuming
* surface wipe-down A decontamination effectiveness check was performed during the cleaning effort by means of biased and unbiased measurements on the surface of the cleaned steel shell using a gas flow proportional counter (GFPC). The criteria for determining when an area was K                    acceptably decontaminated was initially established at c 3 times the local background count K..i                rate as determined by closed window readings in the area. Areas above this value were re-cleaned.
A separate Post Remediation Survey (PRS) was conducted under the guidance of Survey Request (SR) SR-0052 and 0053 (Reference 3.10). The post remediation survey included both surface scans and static measurements. it also included a surface smear survey and sampling of the steel surface in one suspect activation region. Alpha radiation measurements were also taken at select locations. Smears were counted for both beta-gamma and alpha contamination. The results of the PRS survey effort were reviewed before the start of the Final Status Survey (FSS) in this area. The area was then inspected IAW criteria established in Reference 3.11, before being approved for FSS activities.
4.9    This survey design uses a gross activity DCGLw value developed for these survey units from scrape samples of the interior surface of the SNEC CV. These samples were taken at five (5) different elevations in the CV. The sample result that produced the most conservative effective DCGtw value was then used as input to the Compass computer program (see Reference 3.4).
The nearest sample result to the lower head region was taken from the 774' elevation of the CV. However, scrape samples of surface contaminants have been collected from other internal CV shell support ring installation areas. These scrape samples are listed below along with their initial weights and consist largely of paint and concrete residual along with surface scale.

* SNEC Sample No. SXSD3193 - 774' El., 130 gram sample.
The above samples were analyzed by Teledyne Brown Engineering. The results are shown in Attachment 4-1 through 4-6. The gross activity DCGLw is then calculated for each sample result as shown in Attachment 4-7 through 4-12. All samples were decayed to March 1.2003 (see Attachment 4-13).
A gross activity DCGLw was then developed from the relative ratios of the nuclides in the samples. The following values were calculated:
* SNEC Sample No. SXSD3054 16830 dpm/100 cm2.
* SNEC Sample No. SXSD3055 5365 dprml100 cm2 .
* SNEC Sample No. SXSD3124 12877 dpmr/100 cm2.
* SNEC Sample No. SXSD3164 3880 dpml100 cm2.
* SNEC Sample No. SXSD3176 12813 dpm/100 cm2.
* SNEC Sample No. SXSD3193 10714 dpmI/100 cm2.
SNEC sample No. SXSD3164 resulted in the lowest calculated gross activity DCGLw value based on the results of these six samples (3880 dpm/100 cm2), and was chosen to represent the lower head area survey units.
A further correction to the gross activity DCGLw is necessary to address de-listed radionuclides and to correct for activated steel in the SNEC CV. These correction factors are reported in the SNEC LP (Chapter 6 - Reference 3.2). In addition, the SNEC facility has instituted an administrative limit of 75% for the allowable dose for all measurement results. The de-listed radionuclide dose is accounted for within the 75% administrative limit, but the activated steel dose correction is not. Therefore, the 3880 dprnl1 00 cm2 gross activity DCGLw is lowered by the fraction (25 mremny-7.2 mrem/y)/25 mrem/y, which results in 2763 dpm/100 cm2 as the effective limit. The 75% administrative limit is then applied as follows: 0.75 x 2763 dpml100 cm2 = 2072 dpml100 cm2. This value is rounded to 2100 dPmcfOO cm2. See Attachment 5-1.
4.10 Cs-1 37, H-3 and Ni-63 account for the majority of radionuclides in the above listed samples:
* SNEC Sample No. SXSD3054 (95.5% Cs-137 + OA2% H-3 + 3.4% Ni-63) = 99.2%.
* SNEC Sample No. SXSD3055 (89.6% Cs-1 37 + 1.98% H-3 + 6.8% Ni-63) = 98.3%.
* SNEC Sample No. SXSD3124 (84.7% Cs-1 37 + 4.36% H-3 + 10.2% Ni-63) = 99.2%.
* SNEC Sample No. SXSD3164 (62.0% Cs-1 37 + 13.4% H-3 + 22.5% Ni-63) = 97.9%.
* SNEC Sample No. SXSD3176 (73.8% Cs-1 37 + 16.8% H-3 + 8.1% Ni-63) = 98.7%.
* SNEC Sample No. SXSD3193 (57.6% Cs-137 + 19.9% H-3 + 21.1% Ni-63) = 98.5%.
0                  H-3 and Ni-63 provide no additional counting efficiency for this survey design. Cs-137 provides the only reasonably detectable radionuclide in this mix. Cs-137's detection efficiency has been checked by SNEC personnel using ISO standard 7503-1 methodology (Reference 3.15). The SNEC facility uses only the lowest reported efficiency from the available instruments as input to the survey design process. Attachment 6-1 indicates an

l CV Interior, 774' El. and Below, FSS Survey Design Instrument efficiencyof 0.471. The ISO value of 0.5 is used as the source efficiency. The instrument S/N is 120583 and the probe S/N is 92508.
Other Instruments may be used during the FSS but they must demonstrate an efficiencyat or above the value listed above for the Instrument efficlenmy.
4.11    The current version of Compass (version 1.0) does not perform well when using the gross activity option. Therefore, an alternative will be implemented for this survey design. The alternative approach involves several small changes that wig not negatively impact the survey design process. These changes are:
4.1 1.1 For this survey design, the efficiency will be input as follows:
* 4 =0.471
* E, [0.6 (ISO for Cs-137 energy betas)] x [the fraction of Cs-137 in the source area, which would be 1 for the Cs-137 calibration source or 0.62 for Cs-137 in the CV lower head survey units] x [any surface condition that impacts efficiency e.g., the impact from an increase in the average distance between the detector and source caused by a rough surface].
4.11.2 A radionuclide will be created in the library of Compass called OGross Activity'. This radionuclide will have the same nuclear parameters as Cs-137 (half-life, decay time, etc.). The effect will be (when called up) that Gross Activity" will replace Cs-137 on the print-out from the Compass program (administrative impact only).
4.11.3 Only 'Gross Activity' will be used in the Compass program for this survey design.
However, the Area Factors (AF) input to Compass will be for Co-60, which is the more conservative of all the AF values for radionuclides present in the chosen mix.
Co-60 AF values are very dose to Cs-137 AF values.
4.12 The detectors physical probe area is 126 cm2 , and the instrument is calibrated to the same source area for Cs-137. The gross activity DCGLw is taken to be 2100 dpm/100 cm2 x (126 cm2 physical probe areal100 cm2) = 2646 x (0.62 disintegrations Cs-137/disintegrations in mix) x c, (0.471) x a, (0.5) which yields -386 net cpm above background (Compass calculates 397 ncpm as the gross beta DCGLw). The 0.146 count per disintegration counting efficiency considers only the Cs-137 contaminant present in the sample material matrix, and is calculated by: Ec(OA71) x Es (0.5) x 0.62 disintegrations Cs-137/total disintegrations in mix = 0.146.
4.13 No corrections for backscatter are made for this steel surface. Therefore, the source term will be overestimated in all areas where there is no loss in efficiency due to surface defects.
Since all areas of the CV are rigorously decontaminated using the same technique(s), it is assumed that areas having significant surface defects (dents, weld buildup, etc.), are well represented by adjacent areas that do not have significant surface defects. Defect areas represent a very small fraction of the total surface area of these survey units. Therefore no additional efficiency correction factors will be applied to this survey design.
K)      4.14 Attachment 7-1 provides some initial measurement values from the lower bowl section of the SNEC CV (post-decontamination). The average closed window reading is 161 cpm and the average open window reading is 175 cpm. Attachment 7-2 is reference area steel background values taken from the Williamsburg site. The average closed window reading is 200 cpm. The open window background reference area reading is corrected to approximate

This value is then assumed to represent the additional ambient level in the open window readings in the off-site reference area at Williamsburg, PA. The result is a true open window background value corrected for the difference in shielding created by the CV lower head elevation below the surface.
4.15  The static beta-gamma MDC calculation is as shown in Attachment 8-1, and assumes a typical background level of -161 cpm (CV area closed window reading). The value calculated is -337 dpml100 cm2 .
4.16  The scan MDC calculation is determined based on a 2 cm/sec scan rate, a 1.38 index of sensitivity (95% correct detection probability and 60% false positive), 0.146 counts/disintegration and a 126 cm2 probe area. This calculation is shown in Attachment 8-2 and 8-3. The value calculated is -737 dpm/100 cm 2 (Compass calculates a value of 934 dpm/100 cm2 which is largely because it does not use the 126 cm 2 probe correction factor in the equation). Since the scan MDC is less than the gross activity DCGLw there is no additional survey points added to the survey design for any survey area.
4.17  The background reference area for this survey is the Williamsburg Coal Fired Steam plant decommissioned site. This site area contains construction residual and facilities of a similar age or older than the Saxton site. The results of this survey are shown in Attachment 7-2.
4.18    The survey units described in this survey design were inspected after remediation efforts were shown effective. A copy of the SNEC facility post-remediation inspection report (Reference 3.11), is included as Attachment 9-1 to 9-15.
4.19    No special area characteristics including any additional residual radioactivity (not previously noted during characterization) have been identified in this survey area.
4.20    The decision error for this survey design is 0.05 for the a value and 0.1 for the p value.
4.21    Special measurements including gamma-ray spectroscopy are not included in this survey design.
4.22    No additional sampling will be performed IAW this survey design.
4.23    The applicable SNEC site radionuclides and their associated DCGLw values are listed on Exhibit I of this calculation.
4.24    The survey design checklist is listed in Exhibit 2.

774' El Ring Area = 74.5 m2/14 = 5.3 m2 C-Plates = 104.8 m2/8 = 13.1 m2 B-Plates = 124.4 m2/12 = 10.4 m2 A-Plates = 26.3 m2/9 = 2.9 m2 The required scan MDC for the above is estimated from Attachment 10-1, as follows:
774' El Ring Area = 5.3 m2 = AF of -2.5 x 2100 dpm/100 cm2 = 5250 dpm/100 cm2.
C-Plates = 13.1 m2 = AF of -1.8 x 2100 dpm/100 cm2 = 3780 dpm/100 cm 2 B-Plates = 10.4 m2 = AF of -2 x 2100 dpml00 cm2 = 4200 dpmlO00 cm2 A-Plates = 2.9 m2 = AF of -6.5 x 2100 dpm/100 cm2 = 13650 dpm/100 cm2 The actual scan MDC is listed on Attachment 10-11 as 934 dpm/100 cm2 (Compass).
Therefore the scan MDC is adequate. No additional measurement points are necessary in any survey unit.

Comments:
: a. Duct tape was found stuck to the TLG ring in several areas. Concrete debris was found on the underside and face of the ring. Notified the D&D Supervisor.
A layer of rust covers the entire ring. Per D&D Engineering (Brosey), the rust will not affect the survey. No action required.
Caulking covers the ring seams for PRI controls.                        Per D&D Engineering (Brosey), no action is necessary.
Caulk was installed clean during installation of ring sections. Final Status Surveys were performed under caulk during ring installation.
The wooden boxes that were installed to protect the ring for PRI need to be removed.                                      Notified the D&D Supervisor
: b. A moving scaffold is currently being used to access the TLG ring. Rad Con will need assistance with scaffold moves during surveying. No action is necessary.
: c. Lighting is poor. Notified D&D Supervisor. He will add additional lighting.
: d. A final inspection is necessary to close out deficiencies listed above. The final inspection will be documented on a new Survey Unit Inspection Check Sheet.

Comments:
: a. Blast grit was found in indentations and weld seams. Duct tape was found stuck to wall in several areas.
Notified D&D Supervisor.
Some rust was found on the steel plates throughout the survey unit. A thin layer of rust has collected on plates after cleaning. Per D&D Engineering (Brosey), the rust will not affect the survey. No action required.
: b. A moving scaffold is currently being used to access the 'C' plates. Rad Con will need assistance with scaffold moves during surveying. No action is necessary.
Found several tabs that were previously welded to the CV to help support the 774' TLG ring. In some locations, the tabs stick out approximately 1 %' making it difficult for detector access during surveying. Per D&D Engineering (Brosey), no action is necessary. Tabs were installed clean during installation of ring sections. Final Status Surveys were performed before tabs were installed.
: c. Lighting is poor. Notified D&D Supervisor. He will add additional lighting.
Qt  d. A final inspection is necessary to close out deficiencies listed above. The final inspection will be documented on a new Survey Unit Inspection Check Sheet.

Donnacia 1.0      PROBLEM STATEMENT 1.1    The purpose of this calculation is to provide a survey plan for the 774 ft El weld area associated with one stiffener support ring located along the interior surface of the SNEC CV.
1.2    This plan incorporates the use of the Compass computer program (Reference 3.2), and the VSP computer program (Reference 3.3). Additionally, instrument information and preliminary survey data have been used to produce this survey plan.
1.3  This plan makes use of conservative assumptions and a radionuclide mix that is conservatively chosen, in the absence of more definitive information.
2.0     
 
==SUMMARY==
OF RESULTS 2.1    The results of this planning calculation are presented in the attachments. The key elements for this survey plan are:
* Scan Speed is initially set at 2.2 cm/second (1 detector width per 4 seconds).
* The effective DCGLw for this measurement plan is taken to be 2100 dpm/100 cm2 .
* The investigation level for the scanning phase of this work is -250 cpm above background.
C>                      Areas should be marked when at or above this level. An open and closed window measurement should then be made at these elevated locations as a part of the scan process (for a fixed time period (1 min.)). At least one re-cleaning and re-measurement cycle should follow.
* A shielded measurement may be used as a reasonable estimate of background in the survey area.
* A net fixed point measurement result of about 580 cpm yields -2100 dpm/100 cm 2 (the DCGLw) for a 1 minute count time.
* Prior to survey, the surface should be clean, dry and free of materials that can interfere with the measurement process. It takes only about 0.005 inches of material of density I g/cc to cut the source detection efficiency by /2. Rust typically has a much higher density than I glcc and therefore it takes very little rust scale to inhibit beta radiation. A thorough cleaning and inspection must be performed prior to performing this survey work. Contact the RSO for guidance.
* Photos should be taken before and after the cleaning process.
* A scrape or smear survey of the area(s) to be surveyed should be performed prior to cleaning the surface to verify the radionuclide concentration mix. Smears should be sent to an off-site laboratory for analysis.
* The WRS statistical testing procedure will be used when the data are to be analyzed. No (t2'                    analysis is necessary    if all static measurements are below the assigned DCGLw (580 net cpm per 100 cm 2 or 2100 dpm/l00 cm2 ).

* The output from the Compass program indicates that the following stat measurement points will be necessary per ring area to satisfy this survey plan. That is, each ring area measuring
                        -10" in height by -471" in length will have the following number of fixed survey points placed randomly. These locations are marked on the attached maps.
: 1. QUADRANT A = 9 Points
: 2. QUADRANT B = 9 Points
: 3. QUADRANT C = 9 Points
: 4. QUADRANT D = 9 Points
* The typical scanning MDC for this survey will be -425 dpm/'100 cm 2. Since this value is <
2100 dpml100 cm2 (DCGLw), there is no Elevated Measurement Concentration (EMC) areas (see Attachments 1-1 to 1-3). These surveys do not result in the release of any activated component of the steel shelL
* All quadrants shall be laid out JAW the areas specified in the previous ring survey plan (see Reference 3.14).

4.0        ASSUMPTIONS AND BASIC DATA 4.1  It is assumed that the detection efficiency for this survey work will be at least that given on Attachment 2-1 for Tc-99. The instrument vendor uses Tc-99 to calibrate all Ludlum 2350/43-68 Gas Flow Proportional Counter (GFPC) systems. The current vendor calibration report does not include values for e1 or &#xa3;s For purposes of this plan the reported value is assumed to be et (see Reference 3.9).
4.2  For purposes of this plan, an instrument efficiency of 22.5% for Tc-99 was used. This efficiency is for an energy (Tc-99) that is equivalent to that provided by Co-60. However, the majority of the activity in the assumed radionuclide mix is from Cs-137 (-87%). Sr-90 is also assumed C                  present in the mix. Cs-137 and Sr-90 both have average energies above Tc-99, and therefore the K..>              results of this measurement will be an over-estimate of the residual activities present on the surface of the CV steeL Samples of surface materials will be taken as part of this survey plan.

P. Donnachie  it                            t When these results are analyzed residual surface ac vities for these CV areas will be re-calculated.
4.3    No credit for back-scatter of beta particles from the steel surface is taken in this plan. An estimate of back-scatter for the most probable end-point energy present in the radionuclide mix suggests that this value may be as much as 1.2 (end-point energy of around 200 keV) (see Reference 3.6 & 3.12).
4.4    For purposes of this survey plan, a conservative mix of radionuclides has been assumed. The materials are as described in Reference 3.4. However, the originally recommended limit of 1000 dpm/l00 cm2 (provided in Reference 3.4) is extremely conservative. Therefore, the release limit will be adjusted JAW smear samples taken from the steel shell in both the Storage Well/Reactor Cavity and the Primary compartment of the CV. This should be more representative of the type of contamination present on the CV steel in these areas until a more complete sample set has been assayed. The selected samples (see Reference 3.13) are:
* Sample No. SXSMHA8        -  HAP-8 Smears, 18" Wall Area in the Storage Well, and C
* Sample No. SXSMHAP37        -  HAP-37 Smears, 18" Wall Area in the Primary Compartment.
Both of these sample materials provide similar effective limits, but for purposes of this plan the more conservative mix provided by sample No. SXSMHAP8 has been used.
4.5    The resulting mix from sample No. SXSMHAP8 was entered into the spreadsheet titled, "Effective DCGL Calculator for Cs-137 (dpm/100 cm 2)". The pending DCGL values for surface activity (SNEC LTP - Reference 3.7) is then used to calculate an effective gross activity limit of
                -10611 dpm/lO0 cm2 . This limit would be appropriate if all areas in the CV contained the same mix. However, since a representative sampling of all regions in the CV is currently unavailable, it is prudent to reduce this limit by some safety factor for current field work. The resulting gross count rate will then be assumed (for planning purposes) to be the result of Cs-137 activity on the surface of the CV steel. This is a conservative assumption.
4.6    The actual limit set for this survey work will be 20%/c of the above gross activity value or 0.2 x 10611 dpm/100 cm2 = -2100 dm/00cM2 .
NOTE: SNEC sample analysis results for a sample taken in the area of the 792' El support ring survey, indicated that a gross survey unit limit of -3700 dpm/100 cm 2 would be the maximum limit for that support ring location (SNEC Sample No. SXSD3055).
4.7    No additional surface attenuating media is assumed present on the CV steel surface, ie., the Cy        .
surface of the CV steel is assumed to be clean, dry, free of tar, rusty scale, paint and concrete dust. Contact the SNEC RSO before performing this survey work if there is any question regarding the interpretation of this requirement.

P. DonnachieCl            L              c 4.8    Dimensions of the area to be surveyed have been defin          by SNEC site engineer D. Chokshi and SNEC contractor TLG. The survey area dimensions were then input to a CAD program to complete the survey plan. This ring area is 10" in height and encompasses the entire CV circumference of 157 feet. Because of the varying difficulty in applying physical measurement points within a long narrow band, the ring is divided into four quadrants (A, B, C, & D). Each quadrant represents a survey unit.
4.9    Steel background GFPC measurements were assembled from Reference 3.8 (see Attachment 3-1 to 3-3). These values were input to the Compass program as representative background steel values. These values represent a conservative assumption for initial planning purposes. A more appropriate background set will be used in the assessment phase.
4.10    A static open and closed window GFPC measurement set was performed on the surface of CV in the four survey units - post decontamination. That data set was used to determine an estimate for the mean and sigma of each survey unit (see Attachment 5-1 to 5-2). These values were then input to the Compass program as representative steel count rates in the survey areas (see statistical breakdown on Attachments 6-1 to 6-8).
4.11    For purposes of this plan, each area of - 3.04 m 2 is assumed to be one (1) survey unit, and a MARSSIM (Reference 3.9), Class 1 survey area.
4.12  The survey diagram was imported into the VSP program (Reference 3.3). The assigned static measurement points are randomly selected and placed on the survey map along with their coordinates. Random start systematic spacing was not used for-this survey plan because of the long narrow shape of these decontaminated survey units and their location which is in the middle of a contaminated zone.
4.13  The survey plot in VSP was then imported to a CAD program and the survey points were located and listed. The (0, 0) starting point is the lower left hand corner of each survey unit.
4.14  The Area Factors for this survey plan were selected from the most conservative AF values from Reference 3.7 (Co-60). However, the scan MDC value calculated for this work is less than the DCGLw value, and therefore the AF feature is not used.
4.15  The detector should be in contact with the CV steel for both the scan and static measurements.
Open and closed window readings are performed using a 1/44" piece of Lucite (or equivalent), to cover the face of the probe when making a closed window reading.
4.16  Static measurements are to be performed using the open and closed window technique. A one minute count time is necessary for all static measurements.
C  '    4.17    Survey point location maps are shown in Attachment 9-1 through 9-2.
4.18    Survey coordinates are listed for each quadrant in Attachment 10-1.
