PR3-1 SSGP 1.0 INTR 3 DUCTION This Progress Report contains information on the radiological effects of the Steam Generator Repair Program (SGRP) for Surry Power Station, Unit No. 2, and the measures taken to maintain these effects "as low as is reasonably achievable" (ALARA), during the period June 1 through July 31, 1979. With regard to radiological effects, the major tasks performed dur-ing the reporting period involved installation activities and included: installation of the steam generator lower shelle, in-stallation of removed reactor coolant pipe sections, and the steam generator girth welds. Installation of the steam generator recir-culation and transfer system, as well as ongoing peripheral and llh support activities (including: temporary scaffolding, cleanup and decontamination, health physics support and project supe rvision) also contributed significantly to the total radiological effects assessed during this period. The report sections which follow provide an assessment of the occu-pational radiation exposure expended, the dose reduction techniques employed and their ef fectiveness, and the radioactive ef fluents and solid waste generated during the reporting period.

PR3-2 SSGP 2.0 OCCUP ATIONAL RADIATION EXPOSURES 2.1 General Occupational exposure to radia tion may be conside red the major radiological effect of the SGRP. Thus, s1pificant importance has been placed upon providing an accurate assessment of the collective radiation 2xposure which is expended in performing each of the tasks involved. Estimates of these exposures were presented in summary form in Table 5.3-1 of the report entitled " Steam Generator Repair Program", dated August 17, 1977 and amendments thereto, hereafter referred to as the SGRP report. 2.2 Evaluation of Exposure Data The program establisnad to assess the actual exposures received during the repair effort has been designed to provide data which is compatible with the detail and format of the exposure summary pre-sented in Table 5.3-1 of the SGRP report. This design permits valid comparisons between the es timated and actual exposures for specific tasks. In general, the program utt11zes daily worker exposure data, as recorded by self-reading pocket dos ime t e rs , in conjunction with contractor supplied, worker task data to evaluate current manrem expenditures. The worker task data is standardized to a system of discrete work packages (called Engineering Task Assignments) which was developed during the project planning phase. The use of this system to categorize exposure related work for in-dividuals on a daily basis facilitates the process of compiling an accurate breakdown of the collective exposure expended on the many tasks involved. A more detailed description of this program. and O 4 "' # O s. s' .a.100Js

PR3-3 SSGP the basis for its design, was presented in Section 2.2 of Progress Report No. 2 for the SGRP. 2.3 Description and Format of Exposure Data Table I presents a summary of the occupational radiation exposure expended during the reporting period, the labor and exposure ex-penditures to date (i.e. from project commencement on February 3, 1979 to July 31, 1979), and the original estimated expenditures. The following comments are provided for clarification and should be considered when reviewing the data presented. (a) Additional tasks performed during the report period which were not listed in Table 5.3-1 of the SGRP report have been included in Table 1. S imila rily, exposures received by personnel per-forming functions not directly attributable to any one task have been listed separately. (b) The " Task Status" indications listed in Table 1 are intended to aid in the process of comparing estimated vs. actual manrem expenditures during the repair effort. For tasks indicated as "in progress", significant exposure related work remains to be performed and a realistic comparison is imp rac t ical . For

             " completed" tasks, the manrem and manhour values listed in Table 1 can be considered to represent the major significant expenditures for those tasks, therefore valid comparisons are possible. It should be recognized, however, that factors such as field changes to procedures, dismantling of task related support equipment, localized work area cleanup, etc. may con-h             tinue to contribute small amounts of additional exposure and labor to a task for some time af ter completion is ind icat ed .

PR3-4 SSGP (c) The Phase Subtotals listed in Table 1 are calculated by a summation of values for completed tasks. Expenditures report-ed for " Additional Tasks" and " Unassigned Personnel Categories" are allocated to a particular phase based upon the major acti-vities being performed at the time they are incurred. Thus the Phase Subtotals also include these values for phases which can be considered essentially complete. This is the case for Phase I (Shutdown and Preparatory Activities) and Phase II (Removal Activities). For Phase III (Installation Activities), only one of the listed tasks was completed during the reporting period and thus the Phase Subtotal does not yet include the expenditures mentioned above. 2.4 Conclusions A review of the data presented in Table 1 of this report reveals that the total occupational radiation exposure received for tasks completed as of July 31, 1979 is approximately 9% belcw the original estimate. The significance of this comparison is somewhat d iminis h-ed due to the number of in progress" tasks which could not be included. However, the fact that no worker assigned to the SGRP has to date received radiation exposure in excess of applicable federal standards, and the exposure reductions effected by the techniques described in Section 3 of this report, illustrate clearly that the committment to maintain occupational exposures ALARA is being successfully applied to the repair effort, o a'4~ J .A. 2 op LJ X

PR3-5 SSGP 3.0 APPLICATION OF ALARA PRINCIPLES 3.1 General This section summarizes the specific dose reduction techniques employed during the reporting period. In general, the techniques described were Lnplemented prior to this period; however, their continued application and effectiveness have provided significant benefits (exposure reductions) to a number of tasks performed dur-ing June and July. k'here the available data permits, the following evaluations include a quantitative assessment of the manrem savings which can be attributed to the technique used. Additional informa-tion on the techniques discussed, and huv they relate to the over-all steam generator replacement activities can be found in the SCRP report. 3.2 Temporary Shielding The use of temporary shielding can be attributed with significant reductions in personnel radiation exposure for the SCRP. In the early stages of the p roj e c t , extensive shielding of piping and components within the lower steam generator cubicles was performed to provide these work areas with minimum radiation exposure levels. b'here possible, this shielding has remained in place throughout the repair effort. In order to minimize radiation streaming f rom the exposed reactor coolant pipe ends within the cubicles, specially fabricated bags filled with lead beads were placed inside the pipes. Activities involving work on this piping were thus performed in lower radia-tion fields. These activities consisted prima rily of pipe end a p ~< e ty

                                                                   */ A ( L. ted

PR3-6 SSGP refurbishment , and fit-up and welding of the removed pipe sections, and required a combined expenditure of approximately 130 manrem during the reporting period tas listed in Table 1 under "Installa-tion of Reactor Coolant Pip ing") . Radiation survey data indicates that shielding of the pipe ends was effective in reducing exposure rates for these activities by an average factor of 5, and can thus be attributed with an assumed savings of about 520 manrem. 3.3 Decontamination The decontamination of reactor coolant pipe sections which were removed from the primary system was completed during the last re-port period and a detailed assessment of this process was presented in Progress Report No. 2 for the SGRP. In that report it was shown that an average exposure rate reduction factor of 1,000 was achiev-ed for the pipe sections undergoing decontamination, and that the total expr:ure " cost" expended during this process was approximate-ly 41 manrem. Subsequently, these pipe sections were refurbished in preparation for reuse in the system. The labor involved in this task, although not reported separately from the total to date for installation of reactor coolant piping, has been conse rva tively estimated at 2,500 manhours for the reporting period. The estimate for the previous 60 day period was 2,000 manhours, and thus a total expenditure of 4,500 manhours is calculated for this task. Radia-tion survey data, upon which the reduction factor of 1,000 was based, has shown that without decontamination this task might have required working on pipe sections with average contact radiation n 3 .. 4 g , -

PR3-7 SSGP readings of 5,000 to 10,000 mR/ hour. The resulting exposure to accomplish the task could therefore have reached 45,000 manrem. This projection is provided merely to illustrate the importance of the decontamination technique used and emphasize its contribution to the ALARA committment. 3.4 Training The installation of reactor coolant piping represented the major task performed during the reporting period with regard to occupa-tional exposure. While the shielding and decontamination tech-niques described earlier were ef fective in reducing the radiation exposure rates associated with this task, the use of mock-ups to train the wo rkers involved can be credited with providing reduc-tions in exposure times. Welders, pipe-fitters, riggers and laborers all received extens ive training in the activities to be performed by " dry runs" in full scale piping mock-ups. Completion times were noticeably reduced as the simulated activities were re-peated to naximize each worker's familiarity with the actual job situation. Quantifying the exposure savings which have been realized through the use of mock-up training has not been attempt-ed here, however, the inherent benefits of reducing exposure times for this major task are of significant importance to the ALARA program. 3.5 General Techniques The more general procedures and practices which have been utilized during the reporting period to assure adequate control of occupa-o 4 .. 3 y ..y sJ.A.

PR3-8 SSGP tional radiation exposure and to maintain this exposure ALARA are described briefly below. (a) Periodic work area cleanup and debris removal is performed to avoid buildups and maintain good radiological working condi-tions. (b) Piping, valves and other components which must be refurbished prior to reuse are removed from the containment to allow this work to be performed in an area where exposure rates are lower. A special refurbishment building was constructed for this pur-pose. (c) Other general techniques and programs which were previously described in Progress Report Nos. 1 and 2 have remained in effect during this reporting period and are listed here for completeness: (1) comp rehens ive Health Physics and training programs, (2) the " work package" concept for task preplanning and re-view, (3) the project photographic and video-tape documentation, (4) in-containment " rest area" utilization, and (5) contamination control operations and equipment. Although quantitative assessments have not been performed for these

 " general" techniques, all have obvious value in contributing to the overall ALARA program for the steam generator replacement project.

PR3-9 SSGP 4.0 RADI0 ACTIVE EFFLUENTS AND SOLID WASTE 4.1 General Radioactive liquid and gaseous effluents, and radioactively con-taminated solid waste generated during the steam generator replace-ment project are summarized in Table 2. A discussion of each cate-gory is given below. 4.2 Airborne Releases Airborne releases for the reporting period originated primarily from continuous ventilation of the containment during the repair activities. This is necessary to maintain a negative pressure while the equipment hatch is open. The continuous flow is processed through appropriate filter banks to minimize the concentration of airborne particulates released to the environment. Releases for June and July are seen in Table 2 to be consistent with those of the previous two months. No radioiodines or noble gases were detected and the particulates are comprised entirely of those nuclides with relatively long half-lives which would normally be expected at this stage of the repair effort. 4.3 Liquid Releases The composition of radioactive liquid ef fluents released during the reporting period is relatively unchanged from that seen in May. The major contributing nuclides are present at quantities which have remained consistent throughout the project, with the excep-tion of Co-58 which appears to be declining due to its short half-life. A notation has been added to page 1 of Table 2 to indicate those months during which a concurrent outage for Surry Unit No. 1 O g *

PR3-10 SSGP may have contributed to the quantities of radioactive liquids re-leased to the discharge canal. This was necessary since a shared laundry facility is used for both units, and the disposal of laundry waste water continues to be the major source of these effluents. 4.4 Solid Radioactive Waste The disposal of contaminated paper waste, disposable protective , clothing and contamination control materials, and, to a lesser degree, structural materials and components not intended for reuse compriset' the major portion of the solid radioactive waste gene-rated during the reporting period. Shipment of the remaining packages containing solidified decontamination solutions g: aerated during previous periods was also accomplished during June. 3r7130

5.0 CONCLUSION

S The following general conclusions are based upon the info rma t ion contained within this report. (a) Although some variations can be seen when comparing the esti-mated vs. actual exposure expenditures for ind ividual tasks, the total exposure (manrem) expended to date remains below the original es t imate established prior to commencement of work. This result, and the techniques described in Section 3 which have played an important part in achieving it, confirm that the ALARA concept is being ef fectively implemented and applied to the steam generator replacement activities. b) Radioact ive liquid ef fluents have exceeded slightly the total release estimate for activity presented on page 9. A.5-5 of the SGRP report. The total volume released to date is 65% of the es t imatec total. This indicates that liquid effluent concen-trations are somewhat higher than originally ant icipated. It has also been noted that some contributions to the liquid re-leases reported have occurred due to the concurrent outage for Unit No. 1. Nevertheless, the total activity released to date continues to represent only a small fraction (less than 1%) of that normally expected during station operation. (c) Airborne releases of radioactivity remain well below the esti-mates provided in the SGRP report on page 9. A.8-7 and are not anticipated to reach those es t ima tes during the project. (d) Solid radioactive waste generated to date has exceeded the volume and activity est imates originally set forth on page 9.A.9-2 of the SGRP report. This is attributed to the increase O 3 a >. *"*'.? '}i-
