PVNGS-1,26.3 PSAR IlYDROLOGIC ENGINEERING in elevation between the high water level and the crest of the ridge located between the plant site and the Ilassayampa Riber is 33 feet (ridge elevation is 975). Calculations to determine the high water surface during the PMF peak discharge are shown in table 2.4-13. Streambed profiles for realigned East Wash and Winters Wash are l7 provided in figures 2.4-21A and 2.4-21B. The Manning's "n" value of 0.045 which is considered applicable to Winters Wash and East Wash was determined from references which recommended values ranging from 0.035 to 0.050. (30) (31) (32) This value (0.045) is considered conservative for calculating flood flows in ephemeral desert streams in the site area. Ill) In Winters Wash, the standard step method was used to calculate a backwater profile from Section D, a potential con-striction in the channel. Data of the cross sections used to determine the high water surface during the PMF peak discharge are shown in table 2.4-14. The computed water elevations due to the PMF flood of 172,400 cfs are shown in table 2.4-15. It can be seen that the high water elevation near Unit 3 is 944.7 feet, which is 6.3 feet lower than the grade level of Unit 3. 7 Since the drainage basin of East Wash at the north line of Section 34 extended eastward is only 6.8 square miles and.the area from that point to cross section F is 1.2 square miles, the added area contributes a significant amount of additional drainage to East Wash at cross section F. A PMF was therefore computed at cross section F and found to be 18,700 ft /s. Due to the constricted East Wash channel at cross section E, a PMF 3 of 17,640 ft /s was calculated at cross section E by interpo-lating between the PMF at the north line of Section 34 3 (Arlington Quadrangle) extended eastward (16,600 ft /s) and 3 the PMF at cross section F (18,700 ft /s). The drainage basin of East Wash measured at cross section E is 7.4 square miles. The assumption was made tha the 3:1 slope of the riprapped l June 2, 1975 2.4-41 Amendment 7

Data of the cross sections used to determine the high water surface during the PMF peak discharge are shown in tables 2.14-16 and 2.4-17. I11) 7 The standard step method was used to calculate the back-water profile from cross section F to determine the water sur-face elevation at various cross sections. A PMF of 3 17,640 ft /s was applied at cross section F by assuming the normal depth at this cross section. The computed results are summarized in table 2.4-15. It is shown that the propospd 15l embankment on the site is not inundated by the PMF in East 7l Wash. A construction access road crosses realigned East Wash between Sections G and H of figure 2.4-2. The road crossing is not designed to pass the PMF for East Wash. Prior to fuel loading for Unit 1, either: (1) the road crossing will be removed, 20 (2) a low water crossing will be installed, or (3) the East Wash embankment will be raised, from the road crossing to the q hill near Section G of figure 2.4-2 and the road profile will be modified to maintain an adequate cross-sectional flow area to pass the PMF with 2 feet of freeboard on the East Wash embankment.

The ponds are designed as Seismic Category I structures to remain functional follow-ing the safe shutdown earthquake (SSE). 2.4.8.2.2 Station Makeup Reservoir Makeup water is stored onsite in a below grade impoundment east lR of the power block area as shown in figure 2.4-2. Total sur-face area corresponding to normal operating elevation is 6 80 acres with an active storage capacity of approximately l20 2000 acre-fect. The maximum normal operating water surface elevation of 950 l3 in the reservoir is 1 foot lower than the grade at Unit 3. The reservoir water depth at normal operating elevation is ,6 29 feet. The area capacity curve for the reservoir is shown in figure 2.4-35. An additional 1.5 feet of depth is provided to contain the 6-hour probable maximum precipitation and to accommodate occasional excess flow from the reclamation plant g R F in emergencies. A minimum 3-foot freeboard is provided to accommodate waves and runup. The maximum slope of the 6 reservoir sides is three horizontal to one vertical. Design details for the reservoir are given in figure 2.4-38. Since the inflow is regulated by the reclamation plant and R the reservoir is excavated below grade, the possibility of rupture or an uncontrolled wat r release is very remote. Due to the location of the reservoic and the surrounding terrain, 6 an accidental overflowing of the reservoir will not affect safety-related systems or structures.

PVNGS-1,2&3 PSAR HYDROLOGIC ENGINEERING Evaporation rates for the site area were developed using the R published data listed in references 33, 34, 41, and 42. The average lake evaporation rate is 72.4 inches per year as shown in table 2.4-22B. Average precipitation for the site vicinity 3 is 7.4 inches per year as given in table 2.4-22C. Based on the above, a net evaporation rate of 65.0 inches per year is used in the reservoir design. 20f Table 2,4-22B AVERAGE MONTHLY LAKE EVAPORATION RATE NEAR SITE VICINITY Month Inches Month Inches January 2.2 July 9.9 February 3.1 August 9.0 3 March 5.0 September 6.9 April 6.6 October 5.3 May 9.0 November 3.3 June 9.9 December 2.2 Total 72.4 Amendment 20 2.4-66B Februtry 12, 1979

PVNGS-1,2&3 PSAR IIYDROLOGIC ENGINEERING 2.4.8.2.3 Evaporation Ponds The circulating water system blowdown, waste water from the reclamation plant, and waste water from other miscellaneous station sources are discharged into the evaporation ponds at the rate of approximately 1000 gal / min per unit. Total dis-solved solid content of the influent ranges from 14,500 to 16,900 ppm. The influent carries approximately 100 tons of solids (dry weight) per day per unit into the ponds. 3 The evaporation ponds could be designed to retain all residual solids over the 40-year plant life. The net lake evaporation rate for fresh water in the site area is 65.0 inches per year (as described in section 2. 4. 8. 2. 2). Due to the continuous evaporation process from the ponds, a consequent buildup of solids results in a progressive decrease in the e"nnor-'4-rate. This decreased rate is provided for in the design of the evaporation ponds. 20 f Analyses indicate a pond 600 acres in area with 20 feet of water depth is sufficient for three units over tne plant life, assuming no blowdown treatment or sludge removal. Average 3 residual solid deposit buildup is less than 12 inches after 40 years. Evaporation ponds are developed in stages as required. Approx-imately 250 acres of ponds will be constructed initially; l17 these will provide sufficient capacity for at least 4 years 20 from the startup of Unit 1. Subject to the results of con-tinuing studies of blowdown treatnent methods and pond sludge l3 removal alternatives, additional ponds may subsequently be constructed in a similar manner. The site contains sufficient 3 area to accommodate the ultimate pond size should this be required. Due to the nature of existing topography, the pond l February 12, 1979 2.4-66E Amendment 20

The ponds developed during the first stage will be divided into smaller sections through internal dikes. The ponds will be interconnected through overflow weirs or sluice gates. The 20 maximum slope of the ponds will be three horizontal to one 3l vertical. The area capacity curves for each pond section are 7l shown in figures 2.4-39 through 2.4-41. Design details for each evaporation pond section are given in figura 2.4-44. A reserve storage capacity of 1.50 feet of pond depth is provided to contain a 6-hour thunderstorm probable maximum 3 precipitation (PMP) and occasional plant waste water discharge during startup. In addition, a minimum of 2 feet of free-board is provided to accommodate waves and runup. Since the ponds are designed to retain all the taste water, including PMP, over the plant life, no spillway or outlet structures are provided. I k Amendment 20 2.4-66F February 12, 1979

The water will receive additional treatment before scorage with a resulting total dissolved solids (TDS) concentra-tion of about 1000 milligrams per liter. Scepage from the reservoir could possibly reach the mound of perched groundwater under the site. The TDS concentration of the perched ground-water is as great or greater than that of the stored makeup water (section 2.4.13.1) and no adverse effect is expected. 2.4.13 GROUNDWATER The alluvial basins of the dasin and Range Lowlands Physio-graphic Province (16) make up the large reservoir of ground-water in southern Arizona. Nearly 5 million acre-feet of water is withdrawn annually from the groundwater reservoire. The most productive zones consist of thick deposits of sand and gravel that in places are overlain and interbedded with units of silt and clay. Groundwater conditions may range from water table to artesian, and the thickness of sediments ranges from l 1000 to more than 5000 feet. Geological features of an alluvial basin in the Basin and Range Lowlands Province are shown in figure 2.4-22. The lower Hassayampa-Centennial Basin (17) which includes the site area, is a similar basin. Geological features of the site area'are discussed in section 2.5. Alluvial materials in the desert basins of Arizona are uncon-solidated or poorly consolidated. Porosities of the alluvium range from 10 to 40 percent and the average is about 25 percent. Water moves very slowly through the reservoir rocks, generally not more than a few tens or hundreds of feet per year in permeable sediments, and a few inches per year in materials of low permeability. Arizona desert basins contain no natural lakes. Groundwater resei soirs contai n only natural water reserves. The alluvial l 2.4-76

Introduction This report describes an analysis of borehole geophysical logs ac-quired in the environs of the Palo Verde Nuclear Generating Station near Goodyear, Arizona. The interpretations were made at the request of Fugro, Inc., Consulting Engineers and Geologists of Long Beach, California. The purpose of the study was to derive as much '.nformation as possible from available geophysical logs relative to stratigraphic conditions which might exercise controls ove ground-water infiltration and move-ment in the area. Stratigraphic Correlations The stratigraphic sequence of primary interest in this study was con-fined to sediments which overlie the Palo Verde clay. The Palo Verde clay has a distinctive, well-defined, and unmistakeable group of borehole geo-physical repsonses which can be used for stratigraphic correlation in the 20 environs of the PVHGS with great confidence. Unfortunately, the sediments overlying the Palo Verde clay do not display this same consistency of response, and correlations in this upper sequence must be based upon the natural gama response. Although other radiation logs and electric logs ware available for study, they did little to reinforce the natural gama data and displayed a lack of consistency among themselves. The near-absence of corroborative information in the other logs raises questions about the validity of the natural gama correlations in these materials above the Palo Verde clay. Still, there appears to be good similarity of response detail of logs in local areas and gross response similarity over large areas. The natural gama log correlations are thought to define the stratigraphy of the upper sequence despite the fact that they ~ are not substantiated by the other functions. February 12, 1973 Amendment 20

2 Reasons for the lack of agreement between the different logging func-tions in their response to the materials above the Palo Verde clay are not clear. It is assumed, however, that this urper sedimentary sequence at the Palo Verde site may be chemically related to principal source areas of the several strata. This would produce diagnostic natural ganma responses for certain of the strata derived from a common source material. On the other hand, a lack of physical consistency in a single sedimentary unit may be related to laterally changing conditions of deposition. This would cause variations in response of the induced radiation logs within a single sedimentary zone. Lack of continuity between the electric logs is best explained by the fact that physical conditions in the boreholes were widely varyug because of differences ir-the water table location and differences in drilling fluid composition and invasion. g Analysis of the Borehole Geophysics Geophysical correlations are presented in profiles 1-l', 2-2', and 3-3', addended hereto. The stratigraphic sequence above the Palo Verde clay has been divided into eleven geophysical zones bounded by eleven. horizons which are thought to be traceable across the prof.les. The horizons are drawn through points of maximum response of individual strata rather than at the contacts, which tend to be more obscure. Lat-eral changes in lithology across the profiles are recognized within an individual horizon. Comparison of the geophysical responses with the described lithology of cores indicate that high natural gamma activity is associated with fine-grained clastics. Similarly, clean sand zones are marked by low natural gamma activity and siegative log excursions. Amendment 20 February 12, 1979

3 The general base line of all logs is shifted well to the right (to-ward higher gamma activity) of well-defined sand zones and clearly in-dicates the majority of the sediments to be fine-grained. The coarsest sediments in the generally homogeneous section appear to be silts, but the logs suggest most materials to be silty clays, clayey silts, and clays. Low permeability would be expected, generally, below horizon 11, but oc-casional sand lenses are recognized. These seldom are noted in more than a single boring in the gamma log records. The finer-grained silts and clays display much greater lateral continuity. The log responses upon which correlations are based are not highly diagnostic. Therefore, the correlations involve a considerable measure 20 of subjectivity upon the part of the interpreter. Nevertheless, although an individual " pick" may be off by as much as 10 or more feet, strati-graphic sequences appear to repeat themselves well and lend greater con-fidence to the interpretations. Conclusions Geophysical data strongly indicate essentially horizontal layering of strata above the Palo Verde clay. Horizons 1 through 11 of the pro-files suggest such layer-cake stratigraphy which is comprised of alter-nating silts, silty clays, clayey silts, and clays. Geophysical data indicate that the section above the Palo Verde clay could have low to very low hydraulic conductivities. February 12, 1979 Amendment 20 - ~

PVNGS-1,2&3 PSAR APPENDIX 2AD 2AD.2.2.2 Intermediate Fine-Grained Section (Aquitard): The aquitard consists of massive, relatively continuous layers of clays and silty clays with scattered lenses of clayey silt, clayey sand, and silty sand. Locally, secondary structural features such as rootholes and pores are present. This section is equivalent to Lithozone 4 and stratigraphic submembers E through H in the Units 1 through 5 areas and it is well defined throughout the site area (refer to Figure 2AD-3). Thickness ranges f rom 47 to 175 feet and aver'ges 139 feet across the site (refer to Figure 2AD-4. The upper contact, which is un-dulatory yet continuous, is equivalent to a well defined boundary between two distinctive depositional environments that can be clearly identified across the site. Locally the contact is transitional where a few scattered silt and fine sand lenses are encountered. This surface appears to be coincident with the top of stratigraphic unit E in the Units 1 through 5 site specific areas. Beyond the site specific areas, it appears to correspond tc an easily identified unconformity between coarse-grained soil above and thi aquitard for the perched water model when considering relative permeability of the soil. The depo-sitional environment would be defined as lacustrine with periodic fluvial encroachment. Laboratory tests indicate that the predominant soils in this section are hard silty clays (CL) and clays (CL-CH) of medium to high plasticity (Figures 2AD-7 and 2AD-8). The coarser fractions within the interval consist of poorly graded SC, SM, SM-ML, and ML with nonplastic to medium plasticity fines (Fig-ures 2AD-7 and 2AD-8). 2AD.2.2.3 Lower Coarse-Grained Section: This section, de-fined on the basis of lithologic and geophysical logs, is a continuous sequence of silts, silty sand and clayey sands immediately overlying the Palo Verde Clay (L2-3). The coarse-grained soils are locally equivalent to submembers H and J of lithozone 4 identified in the Units 1 through 5 areas. Due to December 8, 1978 2AD-5 Amendment 19

PVNGS-1,2&3 PSAR APPENDIX 2AD the crosional character of its upper portion, the sequence ranges in thickness locally from 0 in the vicinity of buried bedrock highs to 70 feet and averages about 20 feet. The coarse sediments were deposited in a fluvial environment. Laboratory classification of samples obtained from this inter-val indicates that SC, SM, and SM-ML soil types predominate. 2AD.2.3 Permeability Field and laboratory permeability tests results were evaluated to determine reasonable values of permeability (hydraulic con-ductivity) to be used as input to the seepage model for both the upper coarse-grained soils and for the intermediate fine-grained "aquitard" soils. 2AD.2.3.1 Horizontal Permeability of the Upper-Coarse-Grained Section: Field permeability tests were used to establish the 19 permeability of the upper coarse-grained soils. Laboratory permeability tests were not performed on these soils because they are generally too coarse for representative undisturbed sampling. Field permeability test data from the following sources were analyzed to establish a reasonable value of permeability for the uppe r coarse-g rained soils: Field permeability test program conducted by Harding-o Lawson Associates. Details of the program are presented in Appendix 2AS. e Well pump tests near Units 2 and 3. Details are pre-sented in Appendix Sections 2I.4 and 2I.5, respectively.

PVNGS-1,2&3 PSAR APPENDlX 2AD A tabulation of field permeability test results on coarse-grained soils used for this evaluation is presented in Table 2AD-1. E-18 test results are excluded from Table 2AD-1 and are not used for the selection of the horizontal permeability of the coarse grained soil to be used in the seepage analysis. Excessive amounts of suspended solids in the water used for 19 the E-18 tests tended to produce unconservatively low perme-ability values (Refer to Appendix 2AE, Table 2). l The range in permeability tests for the coarse-grained soils at l the locations tested is between 4.9 x 10-5 and 1 x 10 cm/sec. l20 -2 It should be noted that the three tested intervals with the highest permeabilities (E-19-1, E-19-2, and Unit 3 pump test) were tested in soils that were coarser and cleaner than typical. ETsed on a study of visual estimates of gradation in boring and excavation logs, plus laboratory gradation test data, such clean sands have been observed to occur only in isolated lennes or zones. Therefore, a reasonable integratcd value of horizontal permeability for the upper coarse-grained -4 soils across the site is 5 x 10 cm/sec. 19 2AD.2.3.2 Permeability of the Aquitard Laboratory tests were performed during the various phases of site investigations. During the early siting studies, perme-ability tests were performed on small (1 1/2-inch diameter, 1-inch high) undisturbed samples representative of the entire depth of soils at the site. Results of these tests, that evaluated both vertical and horizontal permeabilities were presented in Appendix 2J. Similar tests were performed during the preliminary investigations for the water reservoir and evaporation ponds. Results of these tests are summarized in Table 2AD-2. During more recent studies, related to the seep-age analysis, permeability tests were performed on larger (2 1/2-inch diameter, A to 6 inch high) undisturbed samples February 12, 1979 Amendment 20 2AD-7

PVNGS-1,2&3 PSAR DESIGN OF CATEGORY I STRUCTURES 5. The slope of any 10-foot section of cflindrical liner plate, referred to true vertical, does not exceed 1:120. The shell is not out of plumb in 117 excess of 3 inches overall. 6. A 10-foot straight edge does not show deviations greater than plus or minus 1 inch in the vertical 11 7 direction between seam welds. 7. Sharp bends are not permitted unless provision has been made for them in the design. A sharp bend is defined as any local bend that deviates from the design radius or a vertical straight edge by an offset of more than 1/2 inch in 1 foot. The template used to measure the local deviations is only 1 to 2 feet longer than the area of the deviation itself. 8. The maximum allowable overall as-built dome pro-l20 file shall be within plus 8-1/2 inches and minus 13 inches of the design location. How eve r, any 17 deviation greater than plus or minus 6-1/2 inches from the design location will require engineering evaluation for design acceptability. B. Penetration assemblies 1. Sections 3.8.1.6.6.3.A.2, 3.8.1.6.6.3.A.3, and 3.8.1.6.6.3.A.5 also control the tolerance requirements for penetrations. 2. A 30-inch long template curved to the required radius does not show deviations of more than 3/4 inch when placed against the completed surface of the shell within a single plate section. 3.8-69 Amendment 20 February 12, 1979

Alignment of the axis of large penetrations (greater than 12 inch nominal pipe size), as erected, does not vary by more than 1 from the alignment shown. Alignment of the axis of smaller penetrations (12 inch or smaller nominal pipe size) as erected shall not vary by more than 2 degrees from the alignment shown. Individual penetrations 17 and penetrations in common reinforcing plates other than main steam and feedwater penetrations are located within plus or minus 1 inch of their design elevations and circumferential locations. Main steam and feedwater penetrations shall be located within plus or minus 1/2-inch of their design elevations and circumferential locations. 4. The location of penetrations at the shell in a common reinforcing plate is within plus or minus 1/4 inch of the dimensions shown on the design t drawings. 3.8.1.6.6.4 Post-Tensioning Procedures. All post-tensioning installation work will be inspected by an inspector. All measuring equipment used for installation is calibrated and certified by an approved independent testing laboratory. During tensioning operations, records are kept for comparing force measurements with elongation for all tendons. The resultar.t cross reference provides a final check on measurement accuracy. The tensioning sequence is based on the design requirements to limit the predicted membrane tension in the concrete and to minimize unbalanced loads and differential stresses in the structure. The procedure for prestressing will be carefully worked out with the post-tensioning vendor. All procedures are subject to the engineer's, approval. ' A detailed typical prestressing sequence is shown in fig- !ure6-4ofBC-TOP-5A. Amendment 17 3.8-70 March 1, 1978

RESPONSE

The position of Regulatory Guide 1 -.62 is accepted (refer to chapter 7). REGULATORY GUIDE 1.63: Electric Penetration Assemblies in Containment Structures for Water-Cooled Nuclear Power Plants (Revision 2, July 1978) l20 I

RESPONSE

Except as indicated in the following paragraph, the electric penetration assemblies in the PVNGS containment comply with Regulatory Guide 1.63. The electrical penetration assemblies will not be incorporated with self-fusing characteristica. They will be designed to withstand, without loss of mechanical integrity, the maximum possible fault current versus time conditions (which could 18. occur because of single random failures of circuit overload protection devices) within the two leads of any one de cArcuit, single-phase ac circuit, or the three leads of any one three-phase circuit. The operating time of the backup protection on the faulty circuit will be taken as the minimum permissible time for the maximum fault or overload current to flow without causing any physical damage which affects the mechanical integrity of the electric penetrations.

PVNGS-1,2&3 PSAR CONFORMANCE WITH AEC REGULATORY GUIDES REGULATORY GUIDE 1.64: Quality Assurance Requirements for 17l the Design of Nuclear Power Plants (October 1973)

RESPONSE

The Regulatory Guide endorses a superseded draft issue of the ANSI Standard N45.2.ll. The Bechtel program complies with ANSI N45.2.ll-1974 as interpreted herein. A. Section 3.1. This section implies that all necessary design input (as listed in sectica 3.2) should be available prior to the start of a design activity. In practice, certain design activities are initiated before the firm input requirements are available. (For exam-ple, foundation designs prepared based on preliminary information or equipment sizes and mounting; embedded conduit run based on preliminary estimates of circuit requirements, etc.). The design phase QA program will be structured to assure that all necessary design input { 6 is available before completion of final design of the work affected by the input and that final design input is available for use in verification cf the final design. B. Section 4.1 Design Process General. Paragraph 3 implies tru seability back from final design to the source of design input. In practice, a lit'eral interpretation of this is not always possible. For example, final design drawings do not identify the related calcula-tions. This paragraph will be interpreted to mean that it shall be possible to relate the criteria used and analyses performed to the final design documents and that record files will permit location of analyses supporting specific design output documents.

PVNGS-1,2&3 PSAR CONTAINMENT SYSTEMS Electrical and mechanical penetrations on the airlock are provided with double seals and test connections. Long term surveillance of the containment building post-tensioning system is described in section 3.8.1.7.2. 17 6.2.1.4.3 Testing of Containment Isolation Valves In general the containment isolation valves can be tested using air or nitrogen pressure, and measuring leakage across the valve seat in the direction out of the containment, in accord-ance with the requirements of 10CFR50 Appendix J, for type C testing. Refer to section 6.2.4.4. _ l20 Preoperational and operational tests have not been prepared at this time. However when such procedures have been pre-pared they will include containment integrated leak rate tests, pretest procedur es and requirements. The minimum period of time to be allot.ted for stability of containment conditions prior to initiation of the integrated leak test will be pro-vided. The procedures may include administrative controls to allow type B and C tests to be conducted prior to the type A test to identify leakage paths that could jeopardize the type A tests ~as well as the controls over TVD connections and their useage. This information will be provided in the FSAR. 37 The containment isolation valves for each piping pene: cation are tabulated in table 6.2.15C together with test method and test direction. The table also indicates the status of the valves during containment building, type A test, and whether the system will be vented to the containment and drained during the type A test. Systems connected to the reactor coolant pressure boundary will be vented but not drained of water during type A tests. Systems connected to the secondary side of the steam generator, cooling water systems and other closed systems are not vented February 12, 1979 6.2-62C Amendment 20

PVNGS-1,2&3 PSAR CONTAINMENT SYSTEMS to the containment building during type A test as indicated in table 6.2-15C. Where type C tests can be performed on isolation valves in closed systems the results of the type C test will be added to the type A test if the system is not vented during the type A test. ~ Type C testing of the safety injection lines, containment spray lines, and long term circulation lines is not performed. Justification for this is on the basis that these val es will 37 be opened in the event of a LOCA and therefore leakage across the isolation valves is not pertinent. If the valves are sub-sequently closed, the containment pressure will have dropped and reactor coolant will provide a water seal thus eliminating any leakage across these valves. Reactor coolant will be replen-ished by the containment spray system and the safety injection . system which meet the single failure criteria. A further con-sideration is that the addition of extra isolation valves in the injection lines for the sole purpose of performing type C test, would impair the operability of these engineered safeguards. Hydrostatic testing and inspection of these isolation valves, and also the associated piping system outside the containment, 20 will be performed periodically under the ISI requirements of ASME XI. During normal operation, the systems are water filled and degradation of valves or piping wculd be readily detected. In the CVCS. system the isolation valves in the reactor drain tank line and the charging line will be type C tested using water. This is justified on the basis that these lines would be filled with water' in the event of a LOCA, the reactor drain 17 tank being below the CB water level, and the charging line filled by connection to the reactor coolant system. The shut- _ down cooling isolation valves will be tested using water since they will always be full during the shutdown phases. To drain to test with air would jeopardize core cooling. Amendment 20 6.2-62D February 12, 1979

PVNGS-1,2&3 PSAR CONTAINMENT SYSTEMS ! Isolation valves connected to the secondary side of the steam generator, such as main steam isolation valves, main steam relief valves, feed water valves, blowdown lines and blowdown sample lines are not considered containment isolation valves, and are not subjected to type C tests. If there is leakage 17 from primary to secondary side, the steam generator may be flooded in the event of a LOCA, to effectively seal any tube leaks. If required, the filling of the steam generators will be performed by the auxiliary feedwater system which meets thu single failure criteria. valves which are type C tested are tested with the applied test 120 pressureinthesamedirectionasthepressureexistingfollowk((1} ing an accident except the butterfly and relief valves listed l20 in table 6.2-15C. Due to the design of these valves the test leakage will inherently be equal to or greater than the leak-age following an accident. 15, Containment pressure monitoring lines are considered an exten-sion of the containment boundary and therefore the isolation valves are not type C tested. 6.2.1.5 Instrument Application The containment atmospheric pressure is continually monitored by four pressure transmitters outside the containment. The 3 ESF actuation design details and logic associated with these pressure transmitters are discussed in chapter 7. Containment spray is actuated by the presence of both an SIAS and high-high containment pressure signal. The high-high containment pressure set point is 30 i 1 psig. The delay time between LOCA with a simultaneous loss of offsite power and conuencement of spray is justified below: 7 Time lag from LOCA to high-high set point 9.5 s (from Figure 6.2-1) Diesel start and establish bus voltage 10 s February 12, 1979 6.2-67 Amendment 20 ~ .-s,. ~-.m-w

PVNGS-1,2&3 PSAR CONTAINMENT SYSTEMS shown in valve arrangements 20, 26, and 27 consists of an access connection attached to and located inside the contain-ment building. A clind flange or hatch encloses the inside end of the access connection. The blind flange or hatch con-tains two 0-ring grooves and a pressure tap. The pressure tap is routed through the blind flange or hatch to the annulus between the two 0-rings. When assembled preparatory to reactor operation, the blind flanges and hatches are secured to the access connection and the annulus between the 0-rings is pressurized to ensure that both seals are functioning. The seal is further tested when test pressure is introduced into the containment. The emergency personnel hatches, personnel locks, equipment hatches and test connection are considered to be part of the containment boundary and therefore General Design Criteria 56 does not apply to the equipment and personnel hatch penetra-2 tions and an isolation valve is not required. l 6.2.4.3 Design Evaluation Refer to CESSAR Section 6.2.4.3. In addition, as noted in section 6.2.4.2, the equipment hatches, the emergency personnel hatches, the personnel lock, and the containment test connec-tion all have closures surrounding the access pipe with a blind flange fitted with double 0-rings which serves as the primary containment seal. The respective access pipe closures and double 0-ringed blind flanges are designed to withstand the forces resulting from the design basis earthquake. Prior to returning to operation after each refueling, the leaktightness of each foregoing mentioned closure is tested by the applica-tion of pressure between the 0-rings. Therefore the require-ments of General Design Criteria 56 do not apply. I ~ ./ 6.2-80A Amendment 15 January 19, 1976

PVNGS-1,2&3 PSAR CONTAINMENT SYSTEMS An operating procedure will require that all manual valves, { such as those shown on valve arrangements 3, 5, 12, 28, and 35, be verified as closed prior to any operation requiring contain-20 ment integrity. This procedure will also include the manual valve in the nitrogen purge line which connects to the main steatn line. i l l Amendment 20 6.2-80B February 12, 1979

PVNGS-1,2&3 PSAR CONTAINMENT SYSTEMS 6.2.4.3.1 CESSAR Interface Evaluation 10 Deleted 6.2.4.3.2 Containment Purge Isolation Valves Two containment purge systems are provided as described in 3 section 9.4. A 30,000 ft / min system is provided for uce 3 during refueling operations. A 2000 ft / min system is provided to reduce airborne concentrations prior to and during contain-14 ment entry whenever the reactor is at power. 3 The containment purge isolation valves of the 2000 ft / min system are 8-inch diameter and are designed to close in less than 5 seconds after receipt of a CIAS. This minimizes the amount of containment atmosphere mass released to the environ-ment in the unlikely event that a loss of coolant accident should occur with these purge valves open. The COPDA program, 3 described in section 6.2.1.3.4.2, is used to calculate the con-tainment atmosphere mass release assuming that the isolation 14l valves close with a constant angular velocity over the 5-second stroke time. The flow characteristics of the valve as a func-tion of differential pressure and valve disc angle are presented in figure 6.2-22A. The containment pressure transients follow-ing the postulated LOCA for the specific breaks evaluated are '3 shown in the corresponding figures in section 6.2. The set-point for containment isolation is 10 psig and purge isolation valve closure is initiated 0.9 seconds after the setpoint is reached. The assumptions and results of the analysis of con-tainment atmosphere release during the time to complete closure of the isolation valves are presented in table 6.2-16A. The maximum containment atmosphere mass released to the environ-ment is for the case of a double ended hot leg break and is 14 gived in table 6.2-16A. The affect of this containment mass release is to reduce the containment peak pressure by less than 0.1 psi. Amendment 14 6.2-86 November 17, 1975

CESSAR Section 6.3.3 was revised by CESSAR Amendment No. 31 to demonstrate that the ECCS design satisfies the criteria specified in " Acceptance 9 Criteria for Emergency Core Cooling Systems for Light-Water Cooled Nuclear Power Reactors" Federal Register Vol. 39, No. 3 dated January 4, 1974. l20 The revised ECCS analytical models used by C-E calculate con-tainment back pressure based upon computer input defining specific containment parameters. The containment parameters selected by C-E as input for the revised analysis is conserva-tive for the PVNGS containments. During reflooding of the core, parameters selected to minimize the containment back pressure is the conservative approacn, since tnis innioits the venting of steam from the reactor vessel. Inhibiting steam 9 flow from the vessel results in a slower recovery rate and higher fuel clad temperatures. Details of the analytical model for containment pressure during reflood are given in = CENPD-132, Section lll.D.2.

PVNGS-1,2&3 PSAR - 6.4 HABITABILITY SYSTEMS The control room essential habitability systems include con-crete radiation shielding, redundant air purification, air conditioning and ventilation systems, personnel protection equipment, first aid equipment, food and water storage, and kitchen and sanitary facilities. The control room normal ventilation system is discussed in section 9.4.1. 6.4.1 HABITABILITY SYSTEMS FUNCTIONAL DESIGN The function of the habitability systems is to permit occupancy of the control room following a loss-of-coolant accident (LOCA), the release of smoke or chlorine external to the l20 control room, or a fuel handling accident. 6.4.1.1 Design Bases - 6.4.1.1.1 Safety Design Bases Safety design bases pertinent to the habitability systems are as follows: A. Safety Design Basis One Radiation exposure of control room personnel following a LOCA does not exceed the guidelines set by 10CFR50, Appendix A, General Design Criterion 19. B.

System Description

A system flow diagram of the control room essential ventila-tion system is shown in figure 6.4-1. A layout drawing and a description of shielding required to maintain habitability of the control room during the course of postulated accidents is provided in section 12.1.2. Environmental design criteria for the air purification system are based on the most limiting conditions resulting from any of the postulated design basis accidents (DBA) and on their duration in accordance with Regulatory Guide 1.52, as noted 34 in table 6.4-1A. Two identical, physical'ly separated high efficiency filtration trains are provided to process intake air flow or recirculated air flow in the control room. Each train consists of a fan, prefilter, high efficiency particulate air (HEPA) filter, 3 carbon adsorber, HEPA filter, cooling coil, and heating elemer.t, in series. Components are listed in table 6.4-1. Table 6.4-1A presents the system design conformance to each position in R Regulatory Guide 1.52. The intake air duct is located such that: It is protected from the effects of a main steamline e break. It minimizes the introduction of airborne radioactive e material from unit release points, e It minimizes the introduction of diesel generator exhaust. The possibility of radioactive material, noxious gases, or steam to be transferred directly into the control room from adjacent areas and buildings is improbable due to the following design arrangements and considerations.

PVNGS-1,2&3 PSAR HABITABILITY SYSTEMS floor at the 140-foot elevation line. There are no piping penetrations into the building above the R 140-foot elevation. The control room is maintained at 1/4-inch Wg pressure above atmospheric to prevent l7 infiltration of air. The volume of the control room 3 and other space protected by the habitability system is 178,000 ft The or' side air supply of 1000 cfm !7 3 will ensure pressurizacion of the area in excess of 1/4-inch Wg sa that all flow of air through the poten-tial leakage paths, doors, ductwork and filtration units, and cable penetrations is outwards and not in-wards. The outside air intake is through the plenum system shown on figure 12.1-6. The inlet to the 3 plenum is through louvered openings at the upper part of the building under the roof. The plenum system is designed as a Seismic Category I Structure, which is an integral part of the building structure. The intake and exhaust louvres are designed to withstand the effects of wind and missiles. The essential HVAC system is inactive during normal operation and thus is not exposed to the atmospheric dust. The outside air supplied during the emergency opera-tion may carry airborne dust. An influx of dust equal to the peak load at the 7 50-foot elevation for the assumed dust storm indicated in section 2.3 for a maximum of 144 hours during a 30-day period would amount to less than 3.5 pounds of dust, of which most would be deposited on the filters. This amount, however, only represents a fraction of the total dust-holding capacity of one of the essential air-handling unit filter banks. February 12, 1979 6.4-5 Amendment 20

PVNGS-1,2&3 PSAR HABITABILITY SYSTEMS 3 The 'wo air intakes are located at the southeast and southwest corners of the control building. There is no direct horizontal path from any sources of radioactivity, noxious gases, or steam from outside to the air intake. D. The adjacent buildings to the control building are the radwaste and auxiliary buildings. Both of these buildings are maintained at a pressure slightly below atmospheric to prevent exfiltration of air. All normal releases from these buildings are exhausted through elevated stacks. This precludes any direct transfer of contaminants to control room intake. C. The control room consists of two air spaces separated by a false ceiling. The upper air space contains cable penetrations (sealed). rom the upper cable spreading from above, Seismic Category I duct hangers, Seismic Category I ceiling hangers, receemca 1_ght fixture enclosures (with power connections) and the seismic Category I HVAC air ducts. There is no leakage path from any of these attachments or penetrations in the 8-inch floor slab of the cable spreading room above the 3l _ control room. The suspended ceiling is not sealed from the lower air space containing the computer and control room equipment. D. The floor of the control room contains sealed cable penetrations from the cable spreading area below the control room. There is, therefore, no leakage path from R the lower cable apreading room through the control room floor into the control room. E. There are two possible doorway entrances into the control room: from the main lobby by elevator or by stairway from the main lobby to the corridor outside the control room, or from the stairway running the full height of the building and 180 away from the main lobby stairway. Entrance to the main lobby is Amendment 3 6.4-5A February 10, 1975

PVNGS-1,2&3 PSAR HABITABILITY SYSTEMS 6.4.1.2.1.8 Ductwork. The system ductwork and dampers are Seismic Category I, designed in accordance with Regulatory 17 Guide 1.52. Ductwork is redundant where required to provide functional support to active components in meeting the single active failure criteria. Leaktight ductwork and isolation dampers are provided where required to isolate the system from unfiltered outside air. In general conformance with Position C.4 of Regulatory Guide 1.52 accessibility and adequate working space for maintenance and testing operations are provided in the design and layout of the air purification system equipment. 6.4.1.2.1.9 Control Access Doors. Control access doors are equipped with self-closing devices that shut the doors automat-ically following the passage of personnel. Alarms are also provided to annunciate if any of the doors is open after a 3 change over to emerger'y operation. Two sets of doors with a corridor between, acting as an air lock, are provided at each of the two entrances to the control room and associated spaces. 6.4.1.2.1.10 Isolation Dampers. System isolation dampers are capable of automatically closing in 7 seconds after receipt of an actuation signal. Total time to fully close the intake 3 damper is 10 seconds (7 seconds for closing plus 3 seconds for detection). 6.4.1.2.1.11 Chlorine Detectors. Redundant chlorine detectors are installed in the control room ventilation outside air intake l3 plenum. These detectors indicate the presence of chlorine in 117 l3 concentrations of at least 1. ppm. Response time is less than 5.1 seconds. !II March 1, 1978 6.4-7 Amendment 17

PVNGS-1,2&3 PSAR HABITABILITY SYSTEFS 6.4.1.2.1.12 Radiation Detectors. Redundant radiation detectors are installed in the control room ventilation outsida 3 lair intake plenum. The unit is responsive to airborne gamma -6 -1 activity between 10 and 10 pCi/cm. 6.4.1.2.1.13 Redundant Smoke Detectors. Redundant smoke detectors are installed in the control room ventilation normal 20 utside air intake ducting. These detectors have sufficient sensitivity to alarm and alert the operator to take appropriata action to prevent smoke from reaching a prohibitive level in the control room. 6.4.1.2.l.14 Breathing Apparatus. Self-contained portable breathing equipment with air bottles is stored within the 14l habitability area of the control room, as described in 2l section 12. 3. 2. 6. 6.4.1.2.2 System Operation Upon receipt of an engineered safety teatures actuation signal as shown on figure 6.4-1, the control room normal ventilation system is isolated and.the essential system automatically put into operation. Transfer to the essential system may also be initiated manually from the control room. 3l Transfer to the essential system consists of closing the normal supply unit isolation dampers and all exhaust isolation dampers, stopping the exhaust fans, opening the isolation dampers to both 14l of the essential outside air supply duct trains, and starting the recirculation fan in both trains. Should, for some reason, the self-closing doors to the control room be prevented from shutting, an alarm reminds the operator to shut them. The essential recirculation fans draw in inlet air, mix it with 14 recirculated air, and push the mixture through HEPA and charcoal filters then discharge into the control room. Since there is no air exhausted, the control room becomes pressurized and this 3 precludes infiltration of outside untreated air with airborne radioactive material. Amendment 20 6.4-8 February 12, 1979

PVNGS-1,2&3 PSAR HABITABILITY SYSTEMS Control room air is recirculated through one of the essential air handling units to be filtered and cooled at a rate of l14 30,000 ft / min. Emergency air intake permits a flow into the 3 3 control room of 1000 ft / min of air from the outside atmosphere. The control room temperature is maintained between 70F and 80F dry bulb and the humidity is maintained below 50% relative humidity. l17 Upon receipt of a high chlorine signal, the control room normal ventilation system is isolated. Isolation may also be initiated manually from the control room. Upon receipt of a high smoke signal, the control room normal ventilation system 20 may be manually isolated. Recirculation of control room air through the normal cooling train is maintained for temperature and humidity control. - 6. 4.1. 3 Design Evaluation 6.4.1.3.1 Safety Evaluation Safety evaluations pertinent to the habitability systems are as lfollows: A. Safety Evaluation One As a result of a postulated Loss-of-Coolant Accident the calculated doses to control room personnel are 1.5 rem whole body gamma and 36 rem beta skin from internal cloud immersion and 7.5 rem thyroid from 7 internal cloud inhalation. Whole body gamma doses directly from containment and from the external cloud are calculated to be 0.66 rem and 0.84 rem respectively. These doses are within the limits specified in General Design Criterion 19. A detailed discussion of the calculational models are given in section 15.4.1. B. Safety Evaluation Two By using chilled water cooling coils and electric f3 heaters, the control room essential air conditioning l14 system maintains the temperature between 70F and 80F,the February 12, 1979 6.4-9 Amendment 20

PVNGS-1,2&3 PSAR HABITABILITY SYSTEMS relative humidity below 50%. The control room 3 pressure is maintained at least 1/4-inch water gage (Wg) above atmospheric pressure during emergency operation. The control room essential ventilaticia 2 system maintains the same temperature and humidity conditions when operating in the isolation mode. C. Safety Evaluation Three 1d Should chlorine be detected in the control room normal outside air intake duct, the normal ventilation system is automatically isolated. Should smoke be 20 detected in the control room normal outside air intake duct, the normal ventilation system can be manually isolated. The sensitivity of the detectors and the closing time of the valves ie cach that the amount of 17l chlorine introduced when '.omogeneously distributed throughout the control room is below allowable con-centrations. Refer to section 7.3 for a discussion of the actuation Logic. For fire protection criteria gn refer to section 9.5.1. D. Safety Evaluation Four Automatic transfer of the control room normal ventila-tion system to the essential system is accomplished upon receipt of either a high radiation signal from the out-side air intake duct radiation detector, receipt of a esfety injection actuation signal or a fuel building high radiation signal from the ESF actuation system. Transfer to the essential system also may be manually initiated from the control room. Local, audible alarms warn the operators to shut the self-closing doors should they be held open, for some reason, after receipt of an emergency transfer signal. Refer to section 7.3 for a discussion of the actuation logic. The transfer to emergency or isolation operation mode 2 does not create a hazard for CO buildup. In case of { 2 Amendment 20 6.4-10 February 12, 1979

A single failure analysis is provided in table 6.4-2. F. Safety Evaluation Six The control room essential ventilation system, the normal ventilation system isolation valves, and intake duct radiation monitors are designed to Seismic Category I requirements. All non-Seismic Category I equipment located in the control building will be separated from the Seismic Category I equipment or supported by Seismic 2 Category I supports in order to prevent the failure of non-Seismic Category I equipment from affecting Seismic Category I equipment.

PVNGS-1,2&3 PSAR HABITABILITY SYSTEMS G. Safety Evaluation Seven A 7-day supply of nonperishable type foods and water is provided. The supply of food and water is sufficient for a prolonged occupancy since outside supplies can be provided within the 7-day interval. 6.4.1.4 Testing and Inspection A detailed program of preoperational and post-operational testing requirements to assure continued system capability will be developed prior to station operation. Emphasis is placed on tests and inspections essential to a determination that performance criteria and operational capability are achieved and maintained. Acceptance test will be performed to verify that the outside air supply of 1000 cfm will provide for the control room and 7 associated space pressurization to 1/4 inch H O as minimum 2 during the control room emergency mode of operation. The control room isolation capability and the ability to process outside air through one of the tro high efficiency filter trains will be tested periodically. The filtration trains will be tested periodically by standard methods in general conformance with Regulatory Guide 1.52, as noted in Table 6.4-1A. Electric heating elements are tested by the manufacturer for 3 capacity. HEPA filter elements are tested individually prior to installation to verify an efficiency of 99.97% with a thermally generated monodisperse 0.3-micron DOP aerosol. HEPA filter banks are tested in-place prior to operation and periodically thereafter to verify efficiency of 99.95% with a cold generated 3l polydisperse 0.7-micron DOP aerosol. Testing is in conformance with ANSI N101.1, and complies with Position C.S.b of Regulatory Guide 1.52. Amendment 7 6.4-12 June 2, 1975

PVNGS-1,2&3 PSAR HABITABILITY SYSTEMS I Impregnated, activated carbon is batch tested prior to loading , into the adsorber section. Acceptance criteria are similar to those described in Table 1 of Regulatory Guide 1.5?. Tests include particle size distribution, hardness, density, moisture content, impregnant content, ash content, impregnant leach-out, and elemental iodine and methyl iodide removal efficiencies at postulated accident conditions. The carbon adsorber section is filled with carbon in a manner to ensure a uniform packing density and to minimize dusting. The adsorber section is leak tested with a gaseous fluorocarbon prior to operation and peri-odically thereafter to verify less than 0.05% bypass. In addition, a periodic laboratory test of a representative sample of the impregnated ace.vated carbon is performed to verify iodine removal efficiencies in accordance with Position C.6 and Table 2 of Regulatory Guide 1.52 for the assigned decon-tamination efficiency and bed depth. Performance of fans is initially verified in accordance with AMCA test codes at the maximum anticipated system pressure drop. Ductwork can be tested for leakage during installation. Testing and inspection of the control room normal outside air intake duct radiation monitors is discussed in section 11.4. Portable equipment such as air samplers, personnel dosimeters, and other radiation analysis equipment applicable to control room habitability is tested and inspected periodically as noted in section 12.3.3.3. 6.4.1.5 Instrumentation Requirements - Details of the radiation monitors used to provide the signal placing the control room essential ventilation system in operation are given in section 11.4. Information including detector locations, type of radiation, detector type, range, and sensitivity are given in table 11.4-3. June 2, 1975 6.4-13 Amendment 7

PVNGS-1,2&3 PSAR HABITABILITY SYSTEMS The chlorine detectors have sufficient sensitivity to detect 3l chlorine in the range from 1 ppm up to 5 ppm and have a 7l response time of 5.1 seconds. 171 The smoke detectors setpoint provides sufficient sensitivity to detect the presence of smoke particles at a level equivalent to 0.5% obscuration (21 volts) or greater and has a response time of 30 seconds at the 0.5% level. This level is conserva-tive since 7% obscuration is the generally accepted level of obscuration which poses a major personnel hazard. The setpoint 20 on the smoke detector of 21 volts corresponds to 0.5% obscura-tion. The detector saturates at 43 volts, which corresponds to 4% obscuration. This gives a margin of safety from the actuation setpoint to the 4% obscuration level of two to one. The 4% obscuration level provides an additional margin of safety from 7% obscuration, the level at which a personnel hazard exists. Differential pressure indication is provided across filters and carbon adsorbers. The following instrumentation is displayed in the control room. e Fan status System air flow e e Room temperature Damper position indications e The instrumentation is designed to Seismic Category I. A des-cription of initiating circuits logic interlocks and periodic testing requirements and redundancy of instrumentation relating to control room habitability appears in section 7.3.

PVNGS-1,2&3 PSAR INTRODUCTION 7.1.1.7 Comparison CESSAR Section 7.1.1.7 is applicable to all systems discussed therein except that portion of the ESFAS designed by Bechtel to cover the supplementary ESFS presented in section 7.1.1.3. 3 The Bechtel designed ESFAS employs one-out-of-two logic, described in section 7.3, as opposed to the two-out-of-four logic supplied by C-E. 7.1.2 IDENTIFICATION OF SAFETY CRITERIA Refer to CESSAR Section 7.1.2. 7.1.2.1 Design Bases Refer to CESSAR Section 7.1.2.1. In addition, the inter-pretation of IEEE 308 and IEEE 279 is presented in Sec-tions 7.1.2.10, 7.1.2.11, and 7.1.2.17. 7.1.2.2 Independence of Redundant Safety-Related Systems Refer to CESSAR Section 7.1.2.2. In addition, for the balance-of-plant safety-related systems compliance to General Design 3 Criterion 17 and Regulatory Guide 1.75 is addressed in section 8.3.1.2.1. 20 February 12, 1979 7.1-2A Amendment 20

PVNGS-1,2&3 PSAR INTRODUCTION detrimental effects on the other channel. A technical specification limitation of a 2 maximum of 1 month is provided for continued operation with one PAM channel of CESSAR Table 7.5-3 out of service. The 1 month continuous outage allowance for one PAM chan-nel was selected as a reasonable time interval which provides sufficient assurance that an 5 accident will not occur when both PAM chan-nels are out of service, and which at the same time does not unduly threaten plant operation due to PAM availability requirements. This period may be extended if another channel I monitoring the subject parameter or related parameter is in service. 4.18 Access to Set Point Adjustments, Calibration and Test Points 2 Administrative controls will be provided for access to calibration points. 4.20 Information Readout One of the redundant channels for each of the analog parameters identified in CESSAR Table 7.5-3 will be continuously recorded. The 5 recorder (s) shall be qualified for operability before and following a seismic event. 4.21 System Repair A defective PAM channel can be detected by testing previously discussed. Replacement 2 or repair of one PAM channel will not affect the other channel. March 7, 1975 7.1-9 Amendment 5

PVNGS-1,2&3 PSAR INTRODUCTION 4.22 Identification The PAM instrumentation channels will not uniquely be identified as such. The chan-nels will be identified to distinguish between redundant channels for the same variable. The balance of the portions of IEEE 279-1971 outlined in CESSAR Section 7.5.2.5 are not applicable. (2) The separation of redundant channels is discussed in section 8.3.1.4. (3) Conformance to Regulatory Position concerning information readout will be met by providing two redundant channels of indication for each of the analog parameters identified in CESSAR Table 7.5-3. One~of the channels will be continuously recorded. (4) Conformance to Regulatory Position concerning provision for instrumentation channels to be energized from the onsite emergency power sup-plies to satisfy the single-failure criterion is discussed in section 8.3.1.1.5. (5) It is understood that the NRC staff is currently preparing implementation guidance for Regulatory 20 Guide 1.97. Until this guidance is issued, it is premature to address this Regulatory Guide. 3 15l 8. Deleted Amendment 20 7.1-10/7.1-11 Deleted February 12, 1979

PVNGS-1,2&3 PSAh ENGINEERED SAFETY FEATURE SYSTEMS There are no interlocks which cross-connect between redundant 12 trains or between ESF and non-ESF systems. 7.3.1.1.6 Redunda.7cy Redundant features of the ESFAS include: A. Two independent channels, from process sensor through and including bistable output relays. B. Two trip paths are present for each actuation signal. C. Each actuation signal actuates two output trains so that redundant system components may be actuated from separate trains. D. Power for the system, ac, is provided from two separate buses. Power for control and operation of redundant actuated components comes from separate buses. Load group 1 components and systems are energized only by the load group 1 bus and load 3 group 2 components and systems are energized only by the load group 2 bus. The result of the redundant features is a system that meets the single failure criterion and can be tested during plant operation. September 29, 1975 7.3-5B Amendment 12

7l PVNGS-1,2&3 PSAR ENGINEERED SAFETY FEATURE SYSTEMS 7.3.1.1.7 Diversity l The system is designed to eliminate credible dual channel failures originating from a commen cause. The failure modes of redundant channels and the conditions of operation that are common to them are analyzed to ensure reasonable assurance that: A. The monitored variables provide adequate information during the accidents. B. The equipment can perform as required. C. The interactions of protective actions, control actions, and the environmental changes that cause, or are caused by, the design basis events do not prevent the mitigation of the consequences of the event. D. The system cannot be made inoperable by the inadvertent actions of operating and maintenance personnel. In addition, the design is not encumbered with additional l components or channels without reasonable assurance that such additions are beneficial. 7.3.1.1.8 Sequencing There is no sequencing for any ESF equipment other than that necessary for ESF bus loading. The automatic load sequencer is discussed in section 3.3.1.1.3. 7.3.1.1.9 Testing Provisions are made to permit periodic testing of the one-out-of-two ESPAS. These tests cover the trip actions from sensor input through the protection system and the actuation devices. The system test does not interfere with the protective function of the system. The testing system meets the criteria of IEEE Standard 338-1971 and of Regulahory Guide 1.22. I Amendment 20 7.3-6 February 12, 1979

PVNGS-1,2&3 PSAR ENGINEERED SAFETY FEATURE SYSTEMS Section 4 criteria numbers and titles followed by an explanation l as to how they are satisfied. 4.2 Single Failure Criterion The one-out-of-two ESFAS is designed so that any single failure within the system shall not prevent proper protective action at the system level. No single failure will defeat more than one of the two protective channels associated with any one trip function. Although no single failure will defeat more than one of the two protective channels, a single failure may cause spurious actuation. However, this spurious actuation is allowable since it does not create plant conditions requiring protective action nor does it interfere with normal reactor operations. A complete analysis of single failures is presented in table 7.3-15. The worst case single failure is the failure of a group actuation relay to deenergize. This condition causes loss of one of the two redundant sets of associated ESF equipment. An analysis of single failures for the auxiliary feedwater 8 actuation signal is presented in taale 7.3-15A. 4.10 Capability for T and Calibration Testing is described in section 7. 3.1.1.9 and is in com-pliance with IEEE 338 as discussed in section 7.3.2.2.3. 4.11 Channel Bypass or Removal from Operation Testing of the one-out-of-two ESFAS is done by channel actuation. Either one of the two channels may be calibrated or repaired without detrimental ef' ts on the system. Indi-vidual trip channels may be bypasset to effect a single channel 7 logic on the ESFAS signal. Maintenance and calibration of the bypassed channel can be accomplished in a short time interval. Probability of failure of the remaining channel is acceptably low during such maintenance periods. Amendment 8 7.3-40 June 20, 1975

6.1 DESCRIPTION

7.6.1.1 Reactor Coolant Pump Cooling Water Supply Monitoring Safety grade instrumentation is provided to detect the loss of cooling water to the reactor coolant pumpa in order to ensure that the operator will have sufficient time to initiate manual tripping of the pumps to protect the pumps from seal failure. The cooling " ster flow rate to each pump is monitored by two redundant flow transmitters. If the cooling water flow rate is reduced below the minimum required for pump operation, a low flow signal will be initiated in each flow channel for the affected pump. The low flow signals will indepencently actuate their respective Class IE redundant alarm system channels in the control room. The setpoint for alarming will be selected with sufficient margin to assure that proper operator action 20 will be taken. (Refer to sections 7.6.1.2 and 7.6.2.2 for a description and analysis of the Class IE alarm system.) The alarm system utilizes a one-out-of-one logic for each channel. 7.6.1.2 Class IE Alarm System A Class IE alarm system is provided for a limited number of operational occurrences for which no specific automatic actuation of a safety system is required. The Class IE alarm system alerts the operator to keep the plant operating within technical specification limits and prevent equipment damage. The IE alarm ifstem consists of individual visual status indi-cators dedicated to each instrument signal. Separate indicator assemblies are provided for each channel. A common audible alarm is provided for each alarm channel. The alarmed condition requires manual reset, once initiated. February 12, 1979 7.6-1 Amendment 20

PVNGS-1,2&3 PSAR ALL OTHER INSTRUMENTATION SYSTEMS REQUIRED FOR SAFETY The IE alar.r ystem is independent of the normal plant annuncia-tion system and the redundant channels are powered from separate IE Power trains. Operator acknowledgment of IE alarms follows the same procedure used for the normal plant annunciator. 7.6.2 ANALYSIS 7.6.2.1 Reactor Coolant Pump Cooling Water Supply Monitoring Monitoring the cooling water flow rate to the reactor coolant pumps with two visual status alarms for each pump on low cool-ing water flow provides sufficient information to the operator to determine if cooling water is available to each pump and to 20 take appropriate action in less than 30 minutes to protect the reactor coolant pump affected. The instrumentation is provided in compliance with the require-ments of IEEE Standard 279-1971. I 7.6.2.2 Class IE Alarm System The Class IE alarm system utilizes two independent alarm sys-tems, one for each channel. There are no operating bypasses for the IE alarm system or inputs. The audible alarms for each channel must be silenced with the use of a key which is under the administrative control of the shift supervisor. The instrumentation and input signals are provided in compliance with the requirements of IEEE Standard 279-1971. Amendment 20 7.6-2 February 12, 1979

PVNGS-1,2&3 PSAR INTRODUCTION IEEE 308-1971. A Class IE de system provides four channels of 125V control power for Class I3 switchgear, essential ac power inverters, and other engineered safety features (ESF) equipment (refer to figure 8.3-4). 8.1.3 SAFETY-RELATED LOADS Refer to table 8.3-1 for a listing of loads supplied by the Class IE ac system. The ESF loads are indicated thereon. For a listing of loads supplied by the Class IE de systems, refer to table 8.3-5. 8.1.4 DESIGN BASES, STANDARDS, AND GUIDES The following principal design bases are applied to the design of offsite and onsite power systems. 20 8.1.4.1 Offsite Power System The following principal design bases are applied to the offsite power system: A. Electric power from the utility grid to the plant site is supplied by four physically independent offsite sources designed and located so as to minimize the likelihood of sia.ltaneous failure. Refer to section 8.2 for details. B. Three physically independent startup transformers are provided to supply the onsite electric distribution system during startup. After startup the normal plant auxiliaries are supplied from the unit auxiliary trans-former and the Class IE equipment is supplied from the startup transformers. Refer to figure 8.3-1 for details.

PVNGS-1,2&3 PSAR ONSITE POWER SYSTEMS 8.3.1.1.3.5 Permissives. Permissives pertinent to the system include: A. A single key-operated switch at the local control panel is provided for each diesel generator to block automatic and remote manual start signals when the diesel is out for maintenance. When the switch is in the maintenance position, an annunciator is initi-ated in the control room. The switch position is also indicated on the control room safety systems 3 status panel. B. A switch in the control room and a local switch are !? provided in parallel with the automatic start centact to allow a manual start capability. C. During periodic diesel generator tests, subsequent to diesel start and prior to synchronization with the preferred system, a control switch bypasses the circuit breaker automatic closing circuits and interlocks to allow parallel operation with the preferred system. The bypass is indicated on the control room safety systems status panel. The bypass is automatically 3 overridden by an automatic diesel generator start. 8.3.1.1.3.6 Load-Shedding Circuits. Load shedding of the Class IE 4.16kV bus is initiated by detection of undervoltage on this bus using a two-out-of-four coincidence logic of undervoltage relays. Section 8.3.1.1.2.ll.B summarizes the design and setpoint criteria for these relays. The load shed signal is a single one second pulse generated uper detection 18 of an undervoltage occurrence. This pulse acts to: A Shed all loads (the load centers primary breakers (4.16kV) will remain closed while the secondary breakers (4 80V) will be opened) B. Send signal to start diesel C. Trip 4.16kV Class IE bus preferred 4ffsite) power 18 supply breakers September 1, 1978 8.3-31 Amendment 18 M

PVNGS-1,2&3 PSAR ONSITE PCFER SYSTEMS D. Send signal to sequential actuation system (refer to 91 figure 8.3-3 for undervoltage and sequential actuation { system logic) Tripping of the offsite breakers isolates the Class IE onsite power system, including the undervoltage relays, from the off-site power system. There is, therefore, no possibility of subsequent interaction between the load shed and the offsite 18 power system. The return of the Class IE 4.16kV bus to offsite power must be done manually. After load shed, tripping of the Class IE 4.16kV bus offsite supply breaker and subsequent closing of diesel generator breaker to the Class IE 4.16kV bus, the undervoltage relays monitor the standby (onsite) power supply for an undervoltage occurrence. The load shed feature 20 is blocked for 60 seconds during sequencing of ESF loads. Should an undervoltage occur after sequencing is complete, the Class IE 4.16kV loads are shed and the loading sequence restarted. As the undervoltage relays are transferred with the Class IE 4.16kV bus from offsite (preferred) to onsite (standby) power on a loss of offsite cower, no bypass of these relays to prevent 8 interaction of offsite power with the shed feature is required. In additien, as stated in Section 8.3.1.1.2.11.E.6, the technical specifications will include minimum and maximum trip setpoints for the undervoltage relays. The sequencer, upon closure of the diesel generator breaker, will sequence the equipment in prcgrammed steps, which prevents diesel generator instability and minimizes accelerating tire. A fast-responding exciter and voltage regulator ensures voltage recovery of the diesel generator after a load step. The gen-erators use field flashing for voltage buildup during the start sequence. As each generator reaches rated voltage and frequency, the gen-erator breaker connecting it to the corresponding 4.16-kV bus closes. With the SIAS or AFAS (only Load Group 1 for AFAS) 3l a diesel start is initiated, however, connection of the diesel generator to the 4.16-kV bus cannot be made unless the preferred Amendment 20 8.3-32 February 12, 1979

PVNGS-1,2&3 PSAR ONSITE POWEP SYSTEMS source of power is lost. If the preferred source of power is not lost, the diesel will remain running for one hour. The 3 diesel generator can start accepting loads within 10 seconds and be completely loaded within 60 seconds after closure of the l18 diesel generator breaker. All the CESSAR ESF loads will be I sequenced on within 30 seconds after receipt of a starting l12 signal as identified in table 8.3-3. Relays at the diesel generator detect generator rated voltage and frequency condi-tions and provide a permissive interlock for the closing of the respective generator circuit breaker. Upon loss of the preferred source of power without LOCA, the undervoltage system l7 initiates the starting of the diesel generators and sheds all loads. The sequencer then automatically initiates the starting 18 of the safe shutdown loads upon closure of the diesel generator breaker. The load shed feature is blocked for 60 seconds 20 following a Class IE bus undervoltage. If the diesel generator is supplying power to the ESF bus, a 18 subsequent accident signal initiates starting of the loads associated with the second accident signal without shsdding .l3 any operating equipment. 20 If offsite power is lost at some time after an accident and I the required ESF equipment is running and the diesel generator 3 is up to rated voltage and speed, the LOCA sequencer completes restarting of the safety injection pumps within 5 seconds and l7 the auxiliary feedwater pump within 10 seconds (group 1 only) 34 such that: A. Interrupted flow to the core is fully reestablished within 13 seconds. 7 B. Interrupted auxiliary feedwater flow to the steam generator (s) is fully reestablished within 15 seconds.

PVNGS-1,2&3 PSAR y ONSITE POFER SYSTEMS E.3.1.1.3.7 Testing. A start and load reliability test pro-k 2 gram will be established to certify 0.99 reliability for the 15l diesel generators. A valid start and load test is defined as a start from design cold ambient conditions with loading to at least 50% of the continuous rating within the required time interval, and continued operation until temperature equilib-3 rium is attained. Prior to fuel loading, at least 300 valid tests are performed on a PVNGS diesel or a comparable unit. A failure rate in excess of 1 per 100 will require further testing as well as a review of system design adequacy. Proper operation of the diesel generators will be determined by: A. Verifying that on loss of offsite power, the emergency buses have been deenergized and that the loads have been shed from the emergency buses in accordance with design requirements. B. Verifying that on loss of offsite power the diesel generators start on the autostart signal, the emergency buses are energized with permanently connected loads, a the auto-connectet shutdown loads are energized through the load sequencer, and the system operates for five minutes while the generators are loaded with the shutdown 18 loads. C. Verifying that on safety features actuation signal (with-out loss of effsite power), the diesel generators start on the autostart signal and operate on standby for five minutes. D. Verifying that on loss of offsite power in conjunction with a safety features actuation signal, the diesel generators start on the autostart signal, the emergency buses are energized with permanently connected loads, the auto-connected emergency (accident) loads are energized through the load sequences, and the system operates for five minutes while the generators are loaded with the emergency loads.

PVNGS-1,2&3 PSAR ONSITE POWER SYSTEMS 8.3.1.2.1.9 Regulatory Guide 1.41, 1973--Preoperational Testing of Redundant Onsite Electric Power Systems to Verify Proper Load Group Assignments. The requirements of Regula-tory Guide 1.41 are met. The onsite electric power systems, designed in accordance with Regulatory Guides 1.6 and 1.32 are tested as part of the preoperational testing program and also after major modifications. The tests are performed in accordance with the procedures outlined in chapter 14. These verify the independence between the redundant onsite power sources and their load groups. The Class IE power system is functionally tested, one load group at a time, by allowing one load group to be powered only by its associated diesel generator. The redundant load group remains completely disconnected from its associated standby diesel generator. A safety injection signal is simulated to start the standby diesel generators and cause automatic sequencing. Functional performance of the loads is checked. Each test is of sufficient duration to achieve stable operating conditions and thus permit the onse and detection of adverse conditions which could result from impivper assignment of loads. During testing of one Class IE load group, the buses and loads of the redundant load group not under test are monitored to verify absence of voltage on these buses and loads. 8.3.1.2.1.10 Regulatory Guide 1.63, 1978--Electric Penetration 29 Assemblies in Containment Structures for Licht Water-Cooled Nuclear Power Plants.

PVNGS-1,2&3 PSAR PROCESS AUXILIARIES waste to gravity drains, may be checked through instrumentation and alarms in the control room. 9.3.3.8 Instrumentation Application Seismic Category I level alarms meeting the requirements of IEEE-279-1971, except for the redundancy requirements, ar 0 provided for those sumps in the auxiliary building that serve ECCS pump rooms. High-temperature alarms and high-level indication, in addition to the level-operated switch used for pump control, are provided for all sumps in the containment and the auxiliary building to provide backup indication of the presence of large leaks and to provide infromation as to the source. Level alarm is provided for all other sumps as well. Level alarms are displayed ar_J monitored in the control room. 9.3.4 CHEMICAL AND VOLUME CONTROL SYSTEM Reference CESSAR Section 9.3.4 with the clarification that shutdown refueling tanks are not required in the 'VNGS design since the refueling water tank alone is sized to borate the RCS from approximately 5% suberitical cold shutdown concen-tration or hot zero power to the refueling concentration at the end of cooldown. 9.3.4.1 CESSAR Interface Requirements The following CESSAR interface requirements are repeated from CESSAR Section 9.3.4.3. Below are detailed the interface requirements that the CVCS places on certain aspects of the BOP, listed by categories. In addition, applicable GDC and Regulatory Guides, which C-E 10 utilizes in its design of the CVCS, are presented. These GDC Regulatory Guides are listed only to show what C-E considers to be relevant, and are not imposed as interface requirements, unless specifically called out as such in a particular interface requirement.

Two independent sources shall be available to pro-vide electric power to the Chemical and Volume Control System equipment. a. During normal operation, power shall be supplied either from offsite or from the main generator; during startup or shutdown, power shall be available from offsite. ~. An emergency generator shall be utilized to o sup;,1y power to equipment listed in Table 8.3.1-3 following failure of the normal power supply. The electric power requirements for the CVCS equipment are presented in 10 Table 8.3.1-1. 2. Within the plant distribution system, the Chemical and Volume Control System equipment loads shall be supplied by separate buses and motor control centers to minimize the effect of outages. 3. In the event of a failure of a bus, standby equipment connected to other buses shall be placed in operation. B. Protection from Natural Phenomena 1. Design provisions shall be incorporated such that the boron addition, charging and letdown portions of the CVCS are capable of functioning in the event of the maximum probable natural phenomena defined in GDC 2. The interface requirements of Section 3.3.3 and 3.4.5 shall be met. Amendment 10 9.3-24 August 25, 1975
