Revision 1 I November 1, 1980 t 2.0 STUDY RESULTS I The systems required to function following the postulated accidents have been identified and the essential components listed. Environmental service conditions have been established, l Evaluation of environmental qualification test reports have ! I been completed. Data sheets (Appendix D) are provided for essential components subject to harsh environmental service conditions. These data sheets document the qualification of I each component by reference to the qualification test condi-tions, or document action in progress to resolve the status of the component. Table 2-1 provides a tabulation of systems included in the study, percent of system components with I outstanding items, and percent of outstanding qua.'.ification data items. Data sheets for components with outstanding items also contain specific actions to be taken to resolve outstanding I items and justifications for continued station operation while the action items are implemented.

Revision 1 l November 1, 1980 t '.0 STUDY CONCLUSIONS AND RECOMMENDATIONS Investigations in response to NRC IE Bulletin 79-01B indicates that a significant number of components are either not subjected to harsh environmental cervice conditions or have I qualification data documented. Vendors have been contacted and confirming letters have been written te the equipment manufacturers requesting qualification F , if available, or component materials data for analysis. Table 3-1 provides a list of letters written. Resolution of qualification I status for the remaining components is being pursued in one or any combination of the following methods.
- a. Equipment will be subjected to worst case environ-mental service conditions and performance / function l*
I tested following exposure. A test report will be prepared for each test. lg b. Where long-term temperature conditions are based ig on criteria established prior to station operation and referenced in the FSAR, actual worst case plant conditions (including measurements of area temperatures, whcre required) will be utilized to i reanalyze station environments and establish j actual environmental service conditions. Where lE conservatism in design results in lower actual l5 temperatures, qualification will be based on
- actual conditions. Qualification will not be l required where actual conditions reduce low tem-pera' cure harsh environments to nonharsh environments.
- c. Equipment will be replaced with qualified equipment.
- d. Equir nent will be relocated and/or shielded,
- c. Where qualifi:ation data may exist but materials l
data is requiled to determine existence of suitable test reports, additional vendor contacts will be made. Ih
- w Contract packages for qualification testing have been prepared and are scheduled to be issued for bids before January 1, 1981.
l3 Procurement documents for replacement components are being , i lE prepared and are scheduled to be issued for bids during the j ! first quarter of 1981. Vendor contacts have been made and work is in progress where additional qualification data may 'I be obtainable from the vendor. I II l 2 I
Revision 1 I November 1, 1980 Replacement components will be installed during the first refueling outage after the new components are received onsite. When the outstanding items identified in Appendix D are closed I out, all Class lE electrical components will be qualified and the basis of the qualification documented. It is recommended that work continue as outlined above to close out the outstanding items in Appendix D. 4.0 DETAILED EVALUATION 4.1 DEFINITION OF POSTULATED ACCIDENTS NRC IE Bulletin 79-OlB defines the postulated accident conditions to be addressed as the loss-of-coolant-accident / high energy line break (LOCA/HELB) inside the containment and the HELB outside the containment. For the Dresden Nuclear Power Station Unit 3, the LOCA/HELB I inside the containment is discussed in FSAR Sections 5.2.3 and 6.2.7. The HELB outside the containment is discussed in Special Report No. 37, Revision 1, submitted to the NRC in February 1975. In evaluating the effects of HELB, concur-rent multiple breaks are not evaluated. For the LOCA/HELB inside the containment, worst case environ-I mental conditions are established by the LOCA resulting from a double-ended recirculation line break. The environ-mental conditions which result from this accident are provided in Section 4.3 and Appendix C. For a HELB outs!de the con &.inment, Special Report No. 37 identifies the high energy lines and the location of postu-I- lated breaks. In support of the response to IE Bulletin 79-OlB, studies were. performed to establish equipment integrated radiation doses as a result of the postulated accidents. These environmental conditions are discussed in Section 4.3. The following postulated accidents involving HELBs were analyzed to establish the worst environmental conditions:
- a. LOCA inside drywell
- b. Main steam line break in the steam tunnel I
I I g 3

- c. Main feedwater line break
- d. High-pressure coolant injection (HPCI) steam line break
- e. Isolation condenser steam line break
- f. Reactor water cleanup (RWCU) line break i
Where components, because of their location, could be sub-jected to differing environments for the various accidents, the most severe environmental conditions were utilized for qualification. Components located within compartments with ,g postulated HELBs would be subjected to pressure, temperature, !5 and humidity conditions resulting from that HELB, but wguld not be subjected to radiation doses in excess of 5 x 10 rads simultaneously. These se.ne componegts could be subjected to I radiation doses in excess of 5 x 10 rads following a LOCA, but these doses would not be simultaneous with pressure, temperature, and humidtty. To simplify this analysis, qualification data I was initially sought which demonstrated operability of these components for the combination of all environmental conditions. Where qualification could not be demonstrated for the entire g spectrum of conditions simultaneously, components were g evaluated for the conditions associated with each individual accident. Environmental conditions are based on the specific accidents for which the components must function. Components which are exposed to harsh environments during accidents for which they are not required to function do not require qualification for these environments. Where qualification testing is to be performed, testing will be performed for I each postulated environment separately. 4.2 IDENTIFICATION OF CLASS lE COMPONENTS REQUIRED TO I FUNCTION UNDER POSTULATED ACCIDENT CONDITIONS (BULLETIN ACTION ITEM 1) i The Dresden Nuclear Power Station FSAR and emergency proce-dures were reviewed to identify the engineered safety feature systems which are required to mitigate the consequences of the postulated accidents discussed in Section 4.1. These I systems ara those needed to achieve reactor shutdown, contain-ment isolation, reactor core cooling, containment and reactor I heat removal, and to prevent the release of radioactive material to the environment in excess of the guidelines of 10 CFR 100. I J I 4 5
Revicion 1 Novcmber 1, 1980 Appendix A provides the master list of Unit 3 and common systems required to function following all of the postulated
.g acc:. dents discussed in Section 4.1. Table A-1 identifies g which systems are required to function following each of the postulated accidents.
The station piping and instrument diagrams and electrical schematics were reviewed to determire the specific compo-nents which must function following the postulated accidents. Based on this review, a master components list has been I developed for each system identified in Appendix A. The master components list identifies each Class lE and/or essential electrical component that is required to function following the postulated eccidents discussed in Section 4.1. Appendix B provides the master components list for Unit 3 and common systems. Throughout this report Class lE is used
.g in reference to components designed to Class lE as well as 5 components not designed to Class lE, but which are essential following the postulated accidents.
4.3 DEFINITION OF ENVIRONMENTAi, SERVICE CONDITIONS (BULLETIN ACTION ITEMS 3 AND 5) 4.3.1 Inside the Drywell The drywell pressure and temperature response following the I postulated LOCA are provided in FSAR Figures 5.2.11 and 5.2.12, respectively. These figures are included in Appendix C. The maximum humidity inside the drywell is defined in FSAR I Table 5.2.2 as 100%. Chemical sprays are not used in the Dresden design. Demineralized water containment spray is utilized and considered in the evaluation. The Dresden FSAR does not provide integrated radiation doses inside the I drywell. Studies were performed to establish the integrated doses inside th^ drywell for a postulated LOCA. The integrated doses for 1 day, 30 days, and 1 year are provided in Appen-dix C. The study methodology is described in Section 4.3.5. I Radiation doses are evaluated for actual equipment operating times. Appendix C also defines the containment spray fluid. I and provides the maximum drywell pressure, temperature, humidity, and flood elevation. 4.3.2 Outside the Drywell, Subject to HELB HELB is discussed in detail in Special Report No. 37, Revision 1,
;g submitted to the NRC in February 1975. The g environmenual conditions (pressure, temperature, and humidity),
due to a pipe break in the steam tunnel, torus compartment, RWCU heat exchanger room and turbine building are listed in Appendix C. 1 Radiation doses following a HELB are less severe fore notthan the doses associated with a LOCA and are there-provided. Flooding does not occur outside the I I 5
I Rovision O June 9, 1980 I drywell as a result of the postulated HELBs. Chemical and demineralized water spray do not exist outside the drywell. I For this study, the environmental effects of a pipe break are considered only in the compartment in which the break occurs as well as areas open to the break area. 4.3.3 Outside the Drywell, Post-LOCA Radiation Exposures Integrated doses have been calculated for areas outside the I drywell. Doses were established for 1 day, 30 days, agd 1 year exposure. Integrated doses of less than 5 x 10 rads during a component'e service life are evaluated as nogharsh environmental c; lons. Integrated doses of 5 x 10 rads I mnd greater are evaluated as harsh environmental conditions. Appendix C provides integrated doses as a function of expo-sure time for areas containing components identified in I Appendix B. The radiation study methodology is described in Section 4.3.5. 4.3.4 Nonharsh Areas Plant areas which are not covered in the above referenced Appendix C tables are considered nonharsh environmental I areas with respect to HELB and post-LOCA radiation. These areas are either maintained in a suitable environmental condition by safety-related heating, ventilating, and air conditioning (HVAC) equipmtut, or are considered nonharsh because they are controlled to less than 104F prior to the postulated accidents and are relatively large open areas with no large motors or other equivalent heat sources. Where environmental conditions are maintained by HVAC equip-I ment, the HVAC system is provided with redundant components and/or a backup power supply for reliable operation. Safety-related HVAC systems are provided for the following areas: I a. Control room, cable spreading room, battery rooms, computer room, and electrical equipment room j l l
- b. Standby diesal generator room
- c. HPCI room
- d. Low-pressure coolant injection corner rooms 4.3.5 Radiation Study Methodology A radiation study was performed to establish integrated doses to equipment following a postulated LOCA. The core I fission product inventor

g Revision 1 Novemb r 1, g 1980 i l "' document " Radiation Source Information for NUREG 0578 Implementation, Computer Run Identified as SNUMB 7007S" dated November 1979. The fission products were diluted into the appropriate fluid media as follows: Fluid Noble Gases (%) Halogens (%) Other(%) Suppression pool liquid 50 - 1 Reactor coolant liquid 100 50 1 Containment atmosphere 100 25 - Reactor steam 100 25 - Dilution of the fission products was considered using the fluid volume as the dilution media. For components located inside the drywell, only gamma doses were considered if the component was enclosed in a nonorganic material (e.g., valve motor actuators in metal enclosures). I The gamma dose was established based on immersion of the component in the gaseous drywell atmosphere for the time which the component must remain functional. For components I enclosed in organic material (e.g., cable), beta radiation doses were t1so calculated. Where components enclosed in organic matarials are installed in metal enclosures (e.g., I cable in conduit or flex-conduit), beta radiation will be neglected. Inspections have been performed in the Dresden 3 drywell, confirming that all equipment and cable is enclosed in nonorganic materials. Beta doses have therefore not been considered. I For components located outside the drywell, source terms were established for piping systems containing reactor steam, reactor coolant liquid, suppression pool liquid, and I containment atmosphere. Since the piping wall thickness is sufficient to shield against beta radiation, only gamma radiation need be considered. Each Class lE component was I located with respect to the piping systems containing post-LOCA radioactive fluids. The integrated dose was established based on the piping source term, distance from pipe to l l l component, and comt .ient operating time. Where a component I could receive doses from more than one piping system, the doses were added to derive a total dose. Appendix C, Table C-3, provides integrated deses as a function of time I calculated 1 foot from the greatest single source in each major plant area. I I 7
RFicion 1 November 1, 1980 4.3.6 Aging In this, study, the need to consider aging is based on the I evaluation of component design and application. The effects of aging have also been considered based on Enclosure 4 to NRC Bulletin 79-01B, " Guidelines for Evaluating Environmental Qualification of Class lE Electrical Equipment in Operating I Reactors" and NUREG-0588, " Interim Staff Position on Environ-mental Qualification of Safety-Related Electrical Equipment."
- a. Components Located Inside the Drywell The environmental conditions inside the drywell I are defined as harsh (Sections 4.3.1 and 4.3.4) and hence the effects of thermal and radiation aging are evaluated for all Class lE electrical components.
- b. Components Located Outside the Drywell
- 1. Radiation aging The components which are located outside the drywell and steam tunnel are exposed to insignificant amounts of radiation during normal operating conditions. The effects of I radiation aging are therefore not considered in the qualification evaluation of these components.
Under postulated accident conditions some j compongnts may be exposed to greater than 5 x 10 rads (integrated 7;adiation dose ) . I The effects of this short-term radiation exposure are considered in the qualification evaluation. Components located inside the steam tunnel are l evaluated for radiation aging.
- 2. Thermal aging Most areas outside the drywell are maintained I in a suitable environmental condition by safety-related HVAC equipment. The normal
! maximum environmental design temperature is I 103F, which in this study is defined as a nonharsh environment (Section 4.3.4). Thermal aging for these components is not 'g requi .:e d since the normal and post-accident g environments are nonharsh. In addition, temperature extremes (up to 120F) may occur I 8
I Ravicion 1 Novembnr 1, 1980 I in some plant areas. However, these conditions would result only during periods of extreme I outdoor temperatures. Equipment designed and installed per industry standards would be capable of satisfactory operation without
- e. th" 8, ting age-related degradation due to I th oe temperature extremes. Therefore, the effects of thermal aging are not considered for components located in areas where the I maximum ambient temperature is maintained at 120F or below.
I 4.4 EVALUATION OF ENVIRONMENTAL QUALIFICATION DATA (BULLETIN ACTION ITEMS 2 AND 4) g Appendix B identifies all specific components necessary g following the postulated accidents. In addition, this bulletin covers general use electrical items such as motor lubricating oil, sealants, tape, terminal blocks, gaskets, etc. These general use items are discussed in Section 4.5. For each specific component identified in Appendix B, a component evaluation worksheet was prepared. These worksheets I identified the most harsh environment each component would l be subjected to following the postulated accidents. Environ-ments were considered nonharsh when the temperati.re was I controlled to 104F or less and the gaximum integrated radiation dose was less than S x 10 rads. Areas where ! infrequent temperature extremes up to 120F could occur, and l additionally, where temperature variations are not a result 5 of the postulated accidents are considered as mild environments. ( Equipment in these areas fur.ctions normally in the same environ-94 ment as postulated for post-accident conditions. For nonharsh g and mild environments, qualification data is not required. Since industry standards did not exist for environmental qualification of Class lE electrical equipment during the time the Dresden station was designed and constructed, qualification testing was not required for these components when originally purchared. However, many of these same l" components were used i later designs and qualification testing data is availa'oie. Also some testing has been performed by the Nuclear Steam System Supplier in response to NRC IE Bulletin 79-01. These qualification reports have been evaluated to determine their applicability to the components identified in Appendix B. Where applicable j qualification data exists, this data is entered on the l component evaluation worksheets to document the suitability ! of the component.

Revicion 1 Novcmber 1, 1980 I Some components wili be qualified by analysis or a combination I of analysis and testing. In these cases, the component evaluation worksheets will reference the subject analysis and testing and document the suitability of the component. Finally for those components which are exposed to harsh environments and for which data is not available and qual-ification by analysis is not appropriate, the qualification I status will be resolved by testing, replacement, or reloca-tion of the component to a nonharsh environment. I The component evaluation worksheets are provided in Appendix D (Volumes 2 and 3) for Unit 3 and common components. The qualification plan, which will be followed to resolve I outstanding items is discussed in Section 4.5. 4.5 CLAS5 lE EQUIPMENT QUALIFICATION PLAN 4.5.1 Specific Components I Where it has been demonstrated that a component will not function under the postulated environment, an LER will be prepared. Where existing data is not available to demon-stra , qualification of a component, one or more of the I following methods will be utilized to resolve the status of the component: l I a. The component will be tested for worst case environ-mental conditions. ; 1 I b. Analysis of actual in-plant environmental condi-tions will be performed to determine if actual in-plant environmental conditions are narsh. l l

'* 4.5.2 General Use Components I A walkdown inspection of accessible electrical boxes and cable connections was performed in the Dresden Unit 3 dry-well. The inspection was performed following the spring 1980 g refueling outage prior to returning the station to power.
g Mr. J. Hughes, NRC Region III inspector, was onsite and accompanied the inspection team for a portion of the drywell inspection. The purpose of the inspection was to identify miscellaneous general use electrical items (i.e., gaskets, seals, grommets, I terminal blocks, splices, and termination tapes) used inside the drywell. In addition, the condition of cable at the electrical boxes and component terminations was inspected. g Boxes which did not have preassigned numbers were numbered 5 'Y '" 'n8Pection team. These field-assigned numbers were pr( .xed with 79-OlB. The boxes were generally in satisfactory l condition, with minor repairs required of three boxes. This Information was discussed with station electrical personnel who agreed to made the repairs prior to returning the unit to power. Splices and termination tapes were not found in
- the electrical boxes inspected. The results of the electrical box inspection are provided in Table 4-1.
, Where qualification data is not available for existing installed materials, procedures will be written to replace these items with qualified materials. The station inventory of lubricating oils, greases, and other general use items l will include qualified materials and t teps implemented so
.I that only these materia], are utilized on Class lE components.
I 4.6 SUBMITTAL OF LICENSEE EVENT REPORTS (BULLETIN ACTION ITEM 6) In the event any Class lE electrical equipment item is
~l =
determined to be not capable of meeting its required func-tion under the established service conditions, Bechtel will advise Commonwealth Edison Company so that an LER can be
'g submitted. LERs, when submitted, will identify the conditions g under which the component must function and the basis for the determination that it is incapable of functioning. Where justification for continued station operation exists, this -I will be included in the LER. LERs will be submitted within the time frame specified by NRC IE Bulletin 79-OlB. 'I 11 -I
