' y PLANT SYSTEMS BASES The service life of a snubber is evaluated via manufacturer input and information through consideration of the snubber service conditions and associated installation and- maintenance records (newly installed snubber, seal replaced, spring replaced, *in high radiation area, in high temperature area, etc ... }. The requirement to monitor the snubber service life is included to ensure that the snubbers periodically undergo a performance evaluation in view of their age

  • *and operating conditions. -- These records will provide statistical* bases -for .future consideration of snubber service life. The requirements for the maintenance of records and the snubber
  • service life review are not intended to affect plant operation.

, . 3/4:7. 11 SEALED SOURCE CONTAMINATION The limitations on sealed source removable contamination ensure that the total body or individual organ irradiation does not exceed allowable limits in the event of ingestion or inhalation of the source *material. The limitations on removable contamination for sources requiring leak testing, including alpha emitters, is based on 1 O CFR 70.39(c} limits for plutonium. Sealed sources are classified into three groups according to their use, with

'surveillance requirements commensurate with the probability of damage to a source in that group. Those sources which are frequently handled are required to be tested more often than those which are not. Sealed sources which are continously enclosed within a shielded mechanism (i.e., sealed sources within radiation monitoring or boron measuring devices} are considered to be stored and need not be tested unless they are removed from the shielded mechanism.

Attachment 3 Discussion of Changes Surry Power Station

  • Discussion of Changes Surry Power Station Units 1 and 2 Introduction The proposed changes to Surry Units 1 and 2 Technical Specifications support the revised 10 CFR 20 regulations for radiation protection published in the Federal Register on May 21, 1991 and the change_ in. radiological effluent_ reporting requirements published in the Federal Register on August 31, 1992. In addition, a proposed change is included for TS 5 .1-1 and associated Figure 5. 1-1 to correct information for identification of the unrestricted area for gaseous effluents.

Background

The revision of Part 20 to Title 10 of the Code of Federal Regulations (10 CFR 20) incorporates advances and developments in radiation protection that have occurred since the original 10 CFR 20 was issued and implements a new philosophy of radiation protection based on the risk assessments and dose methodologies of the International Commission on Radiological Protection (ICRP) 26 and 30. As a result of this rule revision, several administrative changes are being made to Technical Specifications including reference changes to reflect the new 10 CFR 20 and terminology changes and additions associated with the revised rule.

The proposed changes to the effluent control program section of Technical Specifications are in response to the new dose limits to members of the general public. The revision of Appendix B, Table II, Columns 1 and 2, unrestricted Maximum Permissible Concentrations (MPC) to the effluent concentration values associated with the new dose limits, which are a factor of ten less than current public dose limits, necessitates changes in the liquid and gaseous release rate limits. These changes will provide the operational flexibility necessary to implement the new 10 CFR 20 requirements.

The proposed Technical Specification changes dealing with the change in radiological effluent reporting frequency are in response to a recent change in NRC regulations.

The requirements in 10 CFR 50.36a have been amended to reduce the frequency for submittal of the Radiological Effluent Release Reports from semiannually to annually.

These administrative changes are described in this proposed Technical Specification change request.

The following proposed Technical Specification changes reduce the frequency of

  • submitting the radiological effluent release report from semiannual to annual: TS Surry Discussion of Changes 1

--- ---

  • 1.M, 6.6.B.3, and 6.8.B.3. The revision of 10 CFR 50.36a reduces the frequency for submittal of reports concerning the quantity of principal nuclides released to unrestricted areas in liquid and gaseous effluents from semiannually to annually. The time between submittal of the reports must be no longer than 12 months. We understand that the generic letter under development and review by the NRC supporting both the revised 10 CFR 20 and the change in effluent reporting frequency will specify that the Annual Radiological Effluent Release Report must be submitted by April 1 of each year. This is reflected in our proposed change to TS 6.6.B.3.

The following proposed Technical.Specification.chan.ges..arejn.response to ;the revised 10 CFR 20:

1. 1.U - Revise the definition of unrestricted area.
2. 4. 16 Objective and Bases - Delete the old 10 CFR 20 terminology to avoid misinterpretation of the bases for the sealed source contamination limits.
3. 6.4.N.2 - Revise the liquid effluent release rate limit.
4. 6.4.N.3 - Reflect the relocation of the old 10 CFR 20.106 requirements for liquid and gaseous effluents *to the new -10 CFR 20. 1302.
5. 6.4.N. 7 - Revise the gaseous effluent release rate limit.
6. 6.6.A.2 - Reflect the relocation of the old 10 CFR 20.407 requirements for annual reports to the new 10 CFR 20.2206 requirements.
7. Page TS 6.6 Reflect the correct page number in the Note at bottom of this page.
8. 6.4.8.1 - Reflect the relocation of the old 10 CFR 20.203 requirements for high radiation area to the new 10 CFR 20.1601 requirements.
9. 6.8.8.1.b - Reflect the relocation of the old 10 CFR 20.106 requirements for determining changes in effluent control to the new 10 CFR 20. 1302 requirements.

In addition, the site map defining unrestricted areas for liquid and gaseous effluents, Figure 5. 1-1, is changed to make the identification of the unrestricted area for gaseous effluents consistent with NUREG-0472 and the ODCM .

Technical Specification Changes

1. TS 1.M, Definition of the Offsite Dose Calculation Manual, refers to the Semiannual Radioactive Effluent Release Report. The word "Semiannual" is

-* being changed -to- --Annual." This administrative. change is ..being made

- consistent with -the-change in effluent reporting frequency published- in .the Federal Register, Vol. 57, No. 169, August 31, 1992

2. TS 1.U, Definition of Unrestricted Area, is being revised to adopt the new 10 CFR 20 definition for Unrestricted Area. The.new.definition is based on access not being limited or controlled by the licensee.
3. TS 4.16, Objective for Leakage Testing of Miscellaneous Radioactive Materials Sources, is being revised to delete the obsolete term "maximum permissible body burden." The revised objective is "to maintain doses due to ingestion or inhalation within the limits of 10 CFR 20."
4. TS 4. 16, Bases for Leakage Testing of Miscellaneous Radioactive Materials Sources, is being revised to delete the third sentence in the paragraph description of the bases for sealed source contamination. The information contained in this sentence includes internal dose terminology, i.e., "maximum.

permissible body burden" from ICRP 2 which the internal exposure limits in the old 10 CFR 20 were based upon. The revised 10 CFR 20, which implements

_the guidance of ICRP 26 and 30, has eliminated this term from the regulation.

The bases for sealed source contamination is 10 CFR 70.39(c) which contains limits for plutonium which has not been affected by the 10 CFR 20 revision ..

5. Figure 5.1-1 defines the area outside the security fence as unrestricted for gaseous effluents. Based upon NUREG-0472 and the Radiological Effluent Technical Specifications (RETS), which have been transferred to the ODCM in accordance with Generic Letter 89-01, the unrestricted areas are defined for gaseous effluents at or beyond the site boundary. In order to be consistent with the gaseous effluent dose calculations performed for a member of the public at the site boundary, and based on continuous occupancy, i.e., access is not limited or controlled by the licensee, Figure 5. 1-1 is being revised to show that the unrestricted area for gaseous effluents is at or beyond the site boundary rather than at the security fence. Gaseous effluent dose calculations are not performed for individuals accessing areas between the security fence, which is the boundary for the Protected Area and restricted area, and the site boundary.
6. TS 6.4.B.1 references the old 10 CFR 20.203(c)(2) for control requirements for a high radiation area. This reference is being changed to the 10 CFR 20.1601 (a)(1 ). This administrative change supports the relocation of high Surry Discussion of Changes 3

radiation area control requirements from the old 10 CFR 20.203(c)(2) to the new 10 CFR 20.1601(a)(1). TS 6.4.B.1 is also being revised to acknowledge the additional controls established under the new 10 CFR 20.1602. This will ensure that the measures which, are in place for . controlling -access to high radiation areas are- not, used for very high** radiation areas which require additional controls.

7. The proposed change to the liquid effluent release rate limit in TS 6.4.N.2 is being made in order to accommodate needed operational latitude to facilitate implementation of the revised. 10 CFR 20..requirements. The limitations on liquid effluent concentrations in unrestricted areas is being changed from the current Maximum Permissible Concentration (MPC) values in 10 CFR 20, Appendix B, Table II, Column 2 to 10 times the effluent concentration values in 10 CFR 20, Appendix 8, Table 2, Column 2.
8. The reference to the old 10 CFR 20.106 is being changed to the new 10 CFR 20.1302 in TS 6.4.N.3. This administrative change is being made to reflect the fact that the requirements in the old 10 CFR 20. 106 are now located in the new 10 CFR 20. 1302.
9. The proposed change to the gaseous effluent dose rate limits in TS 6.4.N. 7 is being made*to provide operational* latitude in accordance with the revised 10 CFR 20 requirements. The limitations on the dose rate resulting from gaseous effluents to areas at or beyond the site boundary is being changed from associated doses corresponding to the unrestricted airborne MPC values in 10 CFR 20, Appendix 8, Table II, Column 1 to the following dose rate limits: for noble gases, dose rates of 500 mrem/yr to the total body and 3000 mrem/yr to the skin and for 1-131, 1-133, H-3, and particulate nuclides with half-lives greater than 8 days, dose rate of 1500 mrem/yr to the critical organ.
10. The page number TS 6.6-17 reported in the Note on page TS 6.6-2 is being changed to page number TS 6.6-12.
11. Footnote 2 to TS 6.6.A.2.a references the old 10 CFR 20.407 requirements for reporting the annual exposure report to the NRC. The reference is being changed to reflect the new 10 CFR 20.2206 requirements. This administrative change supports the relocation of the old 10 CFR 20.407 requirements to the new 10 CFR 20.2206.
12. TS 6.6.8.3, the word "Semiannual" is being changed to "Annual" in the title of this section. The frequency for submitting the Annual Radiological Effluent Release Report is being revised to reflect the April 1 date of each year and the applicable reporting period for the previous calendar year rather than the previous six months.

Surry Discussion of Changes 4

13. The reference to 10 CFR 20.106 in TS 6.8.B.1.b is being changed to 10 CFR
  • 20.1302. This administrative change is being made because the effluent control requirements in the old 10 CFR 20.*106 are now located in the new* 10 CFR 20. 1302.
14. TS 6.8.B.3 refers to the Semiannual Radioactive Effluent Release Report. The word "Semiannual" is being changed to "Annual." This administrative change is being made consistent with the change in effluent reporting frequency.

Safety Significance A safety evaluation has been performed for this proposed Technical Specification change request. These Technical Specification changes do not affect the plant design or operation nor do they result in a change to the configuration of any equipment.

There will be no change in types or increase in the amount of effluents released offsite. As a result, this proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.

Proposed changes to the liquid effluent release rate limits are required to accommodate operational flexibility. The basic requirements for Technical Specifications concerning effluents from nuclear power reactors are stated in 10 CFR 50.36a. These requirements indicate that compliance with effluent Technical Specifications will maintain average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 10 CFR 20. 106 and the new 10 CFR 20.1301. These requirements permit operational flexibility that is compatible with considerations of health and safety, including releases which are temporarily higher than the small percentages of average annual release rates, but still within the limits specified in the old 10 CFR 20.106 which reference Appendix 8, Table II MPC limits. These referenced concentrations are specific values which relate to an annual dose of 500 mrem. It is further indicated in 10 CFR 50.36a that when using operational flexibility, best efforts shall be exerted to keep levels of radioactive materials in effluents as low as is reasonably achievable (ALARA) as set forth in 10 CFR 50, Appendix I.

As stated in the Introduction to Appendix B of the revised 10 CFR 20, the liquid effluent concentration values given in Appendix 8, Table 2, Column 2, are based on an integrated dose of 50 mrem in a year. Since a release concentration corresponding to a limiting instantaneous dose rate of 500 mrem/year has been acceptable as a Technical Specification limit for liquid effluents, which applies at all times, as an assurance that the limits of 10 CFR 50, Appendix I, are not likely to be exceeded, it should not be necessary to reduce this limit by a factor of 10.

Surry Discussion of Changes 5

Operational history at Surry Power Station has demonstrated that the use of the unrestricted MPC limits associated with the old

  • 10 CFR 20. 106 as Technical Specification limits has resulted in calculated maximum individual doses to a member of the public that are small percentages of the limits of 10 CFR 50, Appendix I.

Therefore, the use of concentration values which correspond to an instantaneous dose rate of 500 mrem/year, which is 10 times the concentration values stated in the revised 10 CFR 20, Appendix B, Table 2, Column 2, should not have a negative impact on the ability to continue to operate within the limits of 10 CFR 50, Appendix I and 40 CFR 190.

Sufficient operational flexibility is especially important in establishing a basis for effluent monitor setpoint calculations. As discussed above, the concentrations stated in the revised 10 CFR 20, Appendix B, Table 2, Column 2, relate to a dose of 50 mrem in a year. When applied on an instantaneous basis, this corresponds to a dose rate of 50 mrem/year. Because monitor sensitivity and background must be considered, it is impractical to use such a low value for liquid effluent monitor

-setpoints ... Therefore, to accommodate operational flexibility needed for effluent releases, the limits associated with the liquid concentration limits in TS 6.4.N.2 are based on 10 times the effluent concentration values stated in the revised 10 CFR 20, Appendix B, Table 2, Column 2, to apply at all times. The multiplier of 10 is proposed because the annual dose of 500 mrem, upon which the concentrations in the old 10

  • CFR 20, Appendix B, Table II, Column 2, are based, is a factor of 10 higher than the annual dose of 50 mrem, upon which the concentrations in the revised 10 CFR 20, Appendix B, Table 2, Column 2, are based. Compliance with the limits of the new 10 CFR 20. 1301 will be demonstrated by operating within the limits of 10 CFR 50, Appendix I and 40 CFR 190.

Proposed changes to the gaseous effluent dose rate limits is required to accommodate operational latitude under the revised 10 CFR 20. The basic requirements for*

Technical Specifications concerning effluents from nuclear power reactors are stated in 10 CFR 50.36a. These requirements indicate that compliance with the effluent Technical Specifications will maintain average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 10 CFR 20. 106 and the new 1O CFR 20.1301. These requirements permit operational flexibility consistent with considerations of health and safety, which may temporarily result in releases higher than such small percentages, but still within the limits specified in the old 10 CFR 20.106 which reference Appendix B, Table II MPC limits. These referenced concentrations are specific values which relate to an annual dose of 500 mrem. It is further indicated in 10 CFR 50.36a that when using operational flexibility, best efforts shall be exerted to keep levels of radioactive materials in effluents ALARA as set forth in 10 CFR 50, Appendix I.

As stated in the Introduction to Appendix B of the revised 10 CFR 20, the gaseous

  • effluent concentration values given in Appendix 8, Table 2, Column 1, are based on Surry Discussion of Changes 6

an annual dose of 50 mrem for isotopes for which inhalation or ingestion are limiting or 100 mrem for isotopes for which submersion (noble gases) is limiting. Release concentrations corresponding to limiting dose ,-rates less than or equal to -. 500 mrem/year to the whole body, 3000 mrem/year to the skin from _noble gases, and 1500

  • mrem/year to any -organ -from 131, 1-133, H-3 and -all. radionuclides in particulate form with half-'lives greater than 8 days at the site boundary have been acceptable as a Technical Specification limit for gaseous effluents to assure that the limits of 10 CFR 50, Appendix I and 40 CFR 190 are not likely to be exceeded.

Therefore, it should not be necessary to restrict the operational flexibility by incorporating the dose rate associated_with_the_gaseous_efflueot concentration values for isotopes based on inhalation or ingestion (50 mrem/year) or the dose rate associated with the gaseous effluent concentration values for isotopes based on submersion ( 100 mrem/year) ..

Sufficient operational flexibility is especially important in establishing a basis for effluent monitor setpoint calculations. As discussed above, the concentrations stated in the revised 10 CFR ..20, Appendix B, Table 2, Column 1, relate to a dose of 50 mrem or 100 mrem in a year. When applied on an instantaneous basis, this corresponds to a dose rate of 50 mrem or 100 mrem in a year. Use of these low values are impractical as a basis for gaseous effluent monitor setpoint calculations for many situations when --monitor , background, monitor sensitivity, and monitor performance must-be taken into account.

Operational history at Surry Power Station has demonstrated that the use of the dose rate limits of 500 mrem/year, 3000 mrem/year, and 1500 mrem/year as Technical Specification limits has resulted in calculated maximum individual doses to members of the public that are small percentages of the-limits of 10-CFR 50, Appendix I and 40 CFR 190. Therefore, to accommodate operational flexibility needed for gaseous

  • effluent releases, the limits associated with the gaseous release rates listed in the Offsite Dose Calculation Manual (ODCM) will be maintained at the current instantaneous dose rate limit for noble gases of 500 mrem/year to the whole body and 3000 mrem/year to the skin; and for 1-131, 1-133, H-3, and all radionuclides in particulate form with half-lives greater that 8 days, an instantaneous dose rate limit of 1500 mrem/year to any organ. Compliance with the limits of the new 10 CFR 20.1301 will be demonstrated by operating within the limits of 10 CFR 50, Appendix I and 40 CFR 190.

Attachment 5 Significant Hazards Consideration

(J ., .. l,t--. . . . . . . . .

Significant Hazards Consideration In accordance with 10 CFR 50.92, a proposed change to the Operating License (Technical Specifications) involves no significant hazards considerations if operation of the facility in accordance with the proposed change would not: ( 1) involve a significant increase in the probability or consequences of any accident previously evaluated, or (2) create the possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety. The proposed changes are administrative changes which are necessary due to regulatory changes and will not result in significant changes to the facility or its operation. The proposed change has been evaluated against each of the following criteria:

1. The proposed revisions to the liquid and gaseous release rate limits will not result in a change in the types or amounts of effluents released nor will there be an increase in individual or cumulative radiation exposures.

In addition, these changes do not impact the operation or.design of any plant structures, systems or components. These changes ensure compliance with 10 CFR 50.36a and 10 CFR 50, Appendix I and result in levels of radioactive materials in effluents being maintained As Low As Reasonably Achievable (ALARA).

2. The proposed changes do not affect the plant design or operation nor do they result in a change to the configuration of any equipment. There will be no change in types or increase in the amount of effluents released offsite. As a result, this proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
3. Due to the operational flexibility provided by the limits given in this Technical Specification change request, the proposed amendments do not involve any actual change in the methodology used in the control of radioactive wastes or radiological environmental monitoring. Therefore these changes do not reduce the margin of safety.

Virginia Electric and Power Company concludes that the activities associated with these proposed Technical Specification changes satisfy the no significant hazards consideration criteria of 10 CFR 50.92 and, accordingly, a no significant hazards consideration finding is justified.
