ATTACHMENT 1 Outstanding issue 7(a): By Ame ndment 9 to the FSAR, the applicant revised Section 8.2.1.4.1 to state that the 138-kV offsite powe r circuits are dedicated to BVPS-2 rather than being shared between Units 1 and 2. This dedication is incon-sistent with the BVPS-2 design as shown in FSAR Figure 8. l-2. Clarifica-t ion of this inconsistency will be pursued with the applicant, and the results of the staf f review will be ceported in a supplement to this SER.

Response

FSAR changes are in process for Ame ndme nt il to update Figure 8.1-2. Circuits serving BVPS-2 from the 138-kV busses in the switchyard are separate and independent f rom those serving BVPS-1. 1

ATTACllMENT 2 Outstanding lasue 8(a): The voltage levels at the safety-related loads should be optimized for the maximum and minimum load cond it ions that are expected throughout the anticipated range of voltage variations of the of f site power sources. The applicant was requested to pe r f o rm a vo lt age analysis and verification by actual measurement in accordance with Pos it ions 3 and 4 of BIP PS B-1 (NUREG-0800, Appendix 8A). By le t te r dated September 7, 19 84, the applicant provided the partial results of a voltage and load analysis perform in accordance with Position 3 o f BTP PS B-l. On the basis of these results, the staff finds that Class lE equipment will not be subject to vo lt age s exceeding the manuf acturer-recommended tolerances and is acceptable with the following exceptions. (L) The analysia results indicate that vo lt age will drop below 80% when the 6000-h p reactor coolant pump starts. Ju s t if ic at ion fo r this voltage drop will be pursued with the applicant, and the results of the staff review will be reported in a supplement to this SER. (2) The analysis results indicate that h igh vo lt age at ce rt a in 433-V s ub-station and nutor control center (MCC) buses may result in excessively high terminal voltage at certain stors when operating at light lori. The applicant indicated that a vo lt age and load analysis fo r ligh t-Load cases is being performed and would be submit ted for staf f review at a later date. This item will continue to be pursued with the applicant, and the results of the staff review will be reported in a supplement to this SER. (3) The aaalysis results only addressed vo lt ages at the 4160-V and 480-V load center buses, 480-V MCC buses, and the terminals of 4160-V and 480-V toad center-connected loads for both Class IE and non-Cla s s 1E equipment. Analyses not yet completed include terminal voltages at Class lE 480-V MCC loads, Class lE 120-V ac loads, and Class lE 125-V de loads. The applicant ind ic ated that these analyses would be submitted fo r staff review at a later date. This item will continue to be pursued with the applicant, and the results of the staff review will be reported in a supplement to this SER.

Response

(1) This was resolved in letter 2NRC-5-Ol7, dated February 5,1985. (2) Calculations E-86, " Station Service Maximum Voltage Analysis," (4,160-V and 480-V) and E-90, " Class 1E 120-V System Voltages Under Light Load" are attached. These calculations show that the systems provide acceptable maximum voltage levels when operating at light load. analysis for 480-V MCC (3) Calculat ions E-82, E-76, and E-75 provide an loads, 120-V ac loads, and 125-V de loads. Summaries wh ich are attached show ac cep tab le results. The de s ign basis fo r the mtor control center system is to provide a maximum of 414 volts wh ich is 90% of nutor n +ne pla t e voltage fo r stealy stato running conditions. To achieve this design condition, the voltage tirop .tl loaab le is divided between cable le atis aa1 intere.liate basses in tM elect rical d is tr ibut ion system. The minimum 422 vo lt age at the notor control center utilized in calculation E-82 allows fo r approximately 8 volts maximum le ad drop to the no to r terminals. The minimum acceptab le voltage o f 9 0-V d e fo r certain devices in calculation E-75 is based upon equipment manufacturer's specifications. L

ATTACHMENT 3 Outstanding issue 8(b): FSAR Sect ion 8.3.1. L.16 ind ic a te s that safety-related nutors are designed with the capability of accele rat ing the driven eq uipme nt to its rated speed with 80% of motor nameplate voltage applied at the ra) tor terminals. FSAR Section 8.3.1.1.15 indic at es that the design of each diesel generator unit is such that at no time during the loading sequence does the voltage decrease to less than 75% of nominal. In Amendment 3 to the FSAR, the applicant, in response to a request for additional information, indicated that data extrapolated from diesel gen-erator load tests indicated that 79.3% rather than 75% is the largest voltage drop to be expected during the diesel generator load sequence. By letter dated September 7, 19 84, the applicant indicated that testing of the diesel ge ne rato r using actual load and loading sequences to de mo n-strate its capability will be pe r f o rmed. The applicant stated that it will be shown that, for any case in which the generator voltage dips below 80% of nominal, the recovery time plus the load acceleration time is less than the safe stall time of the load. The results of the staff review of this item will be reported in a supplement to this SER. 1

Response

partial summary of the actual factor testing of the Table 4 30.2 3-l is a diesel generators. Test reports (SWEC File Numbe rs ) 27 01. 300-2 30-006A, 2 7 0 2.19 0- 2 30-0 0 6 A, and 27 02.19 0- 2 30- 015 B were reviewed for this l information. l Cases IA through IE are the Sequential Load Tests. Case 11 is taken from l the Motor Start Capability Test. Case III is the Margin Test. 1 Cases LA through IE clearly envelope the diesel generator loading schedule presented in FSAR Table 8.3-3. Cases IA through IE meet the guidelines of Regulatory Guide L.9 for frequency, in that at no time during the loading seque nce does the fre-quency decrease to less than 95 percent of nominal, and the frequency is restored to 98 percent of nominal within 60 percent of each load-sequence time interval. Cases LA through IE meet Regulatory Guide 1.9, although voltage dips to 71%, by recovery to 90% of nominal well within 60% of each load-sequence time interval. Cases IE, 11, and lit e nve lope the instances when the 1250 Hp standby service water pump is energized (note that the 900 Hp service water pump loads will not be present under these scenarios). The standby se rv ice water pumps are non-class IE load,$ fed from the emergency busses, and are designed to operate only upon thu loss of the intake structure. During the au tomat ic loading sequance, the standby service water pumps are blocked from starting until the automat ic loading sequence of the diesel generators is complete. Then, loading of the standby service water pumps onto the Class IE diesel generator system is by nanual action only.

_.. Actual diesel generator loading as indicated in Table 8.3-3 is le s s than that presented in Cases IA through IE, and consequently voi; age levels will be higher and voltage recover to 90% and frequency recovery to 98% will be faster. The motors used in the testing summarized in Table 430.23-1 were 90% and 80% start mtors. These mtors accelerated to rated s peed and continued to run when subsequent loading was applied to the diesel generators. Thereface, the use of 80% voltage start capability motors, in conjunct ion with the diesel generator capability and ' loading schedule, is consistent with Regulatory Guide 1.9. A calculation has been pe rf o rmed along with other plant voltage profile confirmatory calculations to assure that Cisss IF. husses can provide mini-mum required vo lt age levels at stor terminals when loads are sequenced onto the emergency diesel generators. In addit ion, the ability of the BVPS-2 diesel generator sets to start and accelerate all of their required loads in accordance with the established loading sequence will be demon-strated in the field by actual test with plant loads, as discussed in response to SER 8.3.1.3, Attachment 4 to 2NRC-4-140.

ATTACHMENT 4 Outstanding Issue 8(c): Section 6.4.2 of institute of Electrical and Electronics Engineers (IEEE) 387-1977 requires, in part, that the load acceptance test consider the potential ef fects on load acceptance af ter prolonged no-load or light-load ope rat ion of the diesel ge ne rato r. A load acceptance test or anlaysis that demonstrates the capability of the diesel generator to accept the design accident load sequence after prolonged no-load operation will be pursued with the applicant, and the results will be reported in a supple-ment to this SER.

Response

In respanse to questions 430.25, 4 30.54, and 430.92, DLC has explained the following: (a) BVPS-2 procedures require loading of the diesels to at least 25% during testing or maintenance. (b) Whe1 the diosals start automatically, the operator verifies availabil-ity of offsite powe r and immediately returns the units to standby. This limits unloaded running to a very short t ime pe riod. (c) The vendor recommends clearing the engine after 24 hours of unloaded running. Since BVPS-2 operating pract ices limit the accumulated unloaded running time to far le s s than 24 hours each month and the diesel is c le ared monthly during testing, the diesels will be operated far nore conserva-tively than recommended by the vendor. The attached telex from the vendor documents the ability of the diesels to support the loading sequence following 24 hours of unloaded running.

ATTACitMEWI 5 Outstanding lasue 8(d): FSAR Section 8.3. l.l.4 and Table 8.3-3 indicate that for a number of Class LE loads there is a replacement load provided to allow maintenance to be performed while satisfying the single failure criterion. The Be ave r Valley design is such that Class LE load and its replacement may be con-nected to the same Class IE powe r supply at the same time. It is the staff's concern that this simultaneous connection of loads will exceed the capacity of the Class lE power supplies. Identification of loads involved and design provisions t,o preclude simultaneous connections will he pursued with the applicant, and the results of the staf f's review will be reported in a supplement to this SER.

Response

The following electrical loads, classified as swing loads (train colored "gr ee n"), are ab le to be electrically connected to either the Class LE orange or purple bus as described in FSA R Section 8. 3.1.1.4 and are depicted on Figure 8.3-1: 1. 2CilS*P21C (Charging Pump), 4,160 V Class IE 2. 2CCP*P21C (Primary Component Cooling Pump), 4,160 V Class LE 3. 2SWS*P21C (Service Water Pump), 4,160 V Class IE 4. 211VR*FN201C (Containment Air Recirculation Fan), Tripped on CIB Signal (Refer to FSAR Table 8.3-2), 480 V Non-Class LE These swing loads are utilized as replacement loads and will be connected to that one bus W1ich has lost its primary load due to f ailure or mainte-nance. In that case, an exactly equivalent load is substituted. Adminis-t rat ive procedures will be written to preclude operator connection of any two similar loads on one bus, e.g., both A and C pumps on the orange bus or B and C pumps on the purple bus.

ATTACHMENT 6 Outstanding Issue 8(g): The staff concludes that redundant penetrations outside the contalment are adequately separated with the following exception. Train B purple cables are located in the same penetration room and may also share the same elec-trical penetration with train A green cables. In addition, justification for noncompliance with IEEE 384-1974 and the independence of penetrations ins ide the containment were not addressed. These items will be pursued with the applicant, and the results of the staf f's review will be reported in a supplement to this SER.

Response

The statement is not correct that Train A and Train B circuits are run through the same pe ne t r at ion. The same separation criteria are applied both inside and outside containment. l

ATTACHMENT 7 Oittstanding Issue 8(i): IF.EE 334-1974, as augmented by RG 1.75 (Revision 2), prov ide s minimum raceway separat io n guidelines acceptab le to the staff for complying with the physical independence requirements of GDC 17. These guidelines, how-ever, have not been fully followed in the design of Beaver Valley Unit 2. By Amendment 9 to the FSAR, by letter dated October 16, 19 84, and by pro-posed revision of FSAR Section 8.3.1.4, the applicant provided additional descriptive information on the design for raceway separation. On the basis of this information, the staff concludes the following: 1. Separation designs depicted on Figures 8. 3-17, 8.3-21 (detail B), 8.3-30, 8. 3-3 L, 8.3-32 (detail C), 8. 3-33 (de tail C), 8. 3-36, 8. F 37,

8. 3-44, and 8. 3-45 meet RG l.75 and are acceptable.

on Figures 8.3-16, 8.3-21 (detail A), 2. Separation designs depicted 8.3-32 (details A and B), and 8.3-33 (details A and B) do not met the minimum separation guidelines of RG 1.75. Cables are not routed ins ide enclosed raceways separated by one inch or m ee. The cables are, howeve r, separated by two etal barriers (solid tray bottom and top) and by a spatial distance of one inch or m re. The staff concludes that this design meets RG 1.75 and is acceptable. 3. Separation between redundant Class IE circuits depicted on Figures

8. 3-18 and 8. 3-2 3 does not meet the minimum separation guidelines of RG l.75.

Analysis based on testing to justify the lesser separation will be pursued with the applicant, and the results of the staff review will be reported in a supplement to this SER. 4. Separation between Class lE and non-Class lE circuits depicted on the remaining figures ( 8. 3-19, 8.3-20, 8.3-22, 8.3-24, 3.3-25 through 8.3-29, 8.3-34, 8.3-35, 8.3-38 through 8.3-43, 8.3-46, and 8.3-47) does not meet the minimum separation guidelines of RG 1.75. Analysis based on testing to justify the lesser separation will be pursued with the applicant, and the results of the staf f review will be reported in a supplement to this SER. Subsequently, by letter dated January 4, 1985, the applicant presented a proposed test plan fo r justification os separat ion arrangements shown on Figures 8.3-22 (details A through D), 8.3-34, 8.3-35, 8.3-38 (detail A), 8. 3-39 (detail A), 8.3-42, 8.3-43, 8.3-46 (detail A), and 8. 3-47 (detail A) of the FSAR. In ad d i t io n, a new conf igur at ion (which is the same as the configuration shown on FSAR Figure 8.3-18, except that one of the two tray covers shown is removed) was presented fo r justification by the proposed test plan. On the basis of its review of the test plan (ESS0W No. 26VS-843, Revision 1, dated December 27, 19 84), the staff has identified the fo llowing items that require further clarification: 1. Section L.7.3(b) of the plan ind icates that the ef fect of cable aging has not been addressed. It is the staff concern that the test results

~- . will not substantiate the adequacy of the separation arrangements over the life of the plant. 2. Section 2.3.3 of the plan indicates that tempe ature i n asureme nt s on target cables will only be taken at 2-foot intervals for horizontal arrangements and at 4-foot intervals for vertical arrangements. It is the staff concern that the numbe r of m asurements may not be sufficient to conclude that the target cable was not affected. 3. Section 2.5.1 indicates that the basis for acceptance will be that the target cables retain their functional capability. The term "f unct ional capability" has not been defined. Since 5.6.L.2 indicates that one of the test object ives is to demonstrate that a faulted cable will not affect other external cables. The term "will nn af fect" has not been defined. 4. In Section 1. 3 o f Appe nd ix 5.15 o f the plan, it appe ars that cables bigger than No. 6 cables were excluded from heat screening tests. The bases and justification for this exclusion need to be clarified. Each of the above items will be pursued with the applicant, and the results of the staff review will be reported in a supplement to this SER. Outstanding lasue 8(j): Power circuits that traverse the cable spreading room at Beaver Valley are installed in rigid or flexible conduit except at the entrance / exits to floor ' sleeves in the cable spread ing room and control room and at the entrance to the equipment in the control room. In accordance with Position C.12 of RG l.75, this routing should not be considered acceptable. Ju s t i-f ic at ion for alte rnat ive means of compliance will be pursued with the applicant, and che results of the staff's review will be reported in a supplement to this SER. Outstanding Issue 8(k): By letter dated. October 16, 19 84, and in the proposed FSAR Section 1.8, the applicant identified an exception to Position C.9 of RG 1.75. The applicant has proposed the use of solid high-hat covers as shown on FSAR Figure 8.3-48. The use of high hats is not considered an exception to RG 1.75 unless the separation between trays is further reduced by the high hat. If separation is reduced by the high hat, justification of le s se r separation by analysis and test will be pursued with the applicant, and the results of the staff's review will be reported in a supplement to this SER.

Response

l l The above questions concerning elect r ical independence criteria are no l longer valid.

Response

Refer to revised Section 9.5.6.5, Amendment 4, for a description of the instrumentation, controls, sensors, and alarms. The reliability of instrumentation, controls, sensors, and alarms will be maintained and assured through the periodic operability testing of the diesel generator units. The specific testing of these items will be addressed in the BVPS-2 operational procedures and will meet the intent of Regulatory Guide 1.108. 4--- lOS F /2.7 f, PQ.f., 430,9 7 2, 8 Refer to revised Section 9.5.6.5, Amendment 4, for a description of the sensors that alert the operator and the location of alarms that are annunciated. gg,g BVPS-2 operating procedures will also addres actions to be taken in response to alarm conditions. These actions are consistent with the engine manufacturer's guidelines and prevent damage to the diesel engine. Interlocks provided for the diesel generator air starting system are described in revised Section 9.5.6.5, Amendment 4. At a meeting on March 6, 1984, the NRC requested BVPS-2 to verify that the operator is not precluded from starting the emergency diesel generator by a fuel interlock (timed retention of fuel isolation signal), thus creating the possibility of expending the supply of starting air. The control logic prevents energization of the starting solenoids (admits starting air) while the shutdown solenoid-are energized. Should an emergency start signal be initiated within the time that the shutdown time ret-ntion was in effect, the emergency start signal will override the shutdown circuit and the diesel will start. If the diesel were manually tripped while an emergency start signal was present, the shutdown circuit can be reset by depressing the start pushbutton at the location of control. This will allow deenergization of the shutdown solenoids (admits fuel to ' ~/ Amendment 7 Q430.98-1 July 1984

' f ',,. ( BVPS-2 FSAR NRC Letter: September 19, 1983 Question 430.121 (Section 9.5.8) In Section 9.5.8.5 of the FSAR you describe the instruinentation, controls, sensors, and alarms provided in the design of the diesel i engine combustion air intake and exhaust system and their function which alert the operator when parameters exceed ranges recommended by the engine manufacturer. Discuss the testing and frequency of testing necessary to maintain and assure a highly reliable instrumentation,

controls, sensors, and alarm system and where the alarms are annunciated. Describe any operator action required during alarm conditions to prevent harmful effects to the diesel engine.

Discuss systems interlocks provided. Revise your FSAR accordingly 'SRP 9.5.8, Part III).

Response

The diesel engine combustion air intake and exhaust system is a passive system which does not require

controls, alarms, or annunciation.

The reliability of instrumentation will be maintained and assured through the perio,dic eperability testing of the diesel generator units. The specific testing of the instrumentation will be addressed in the BVPS-2 operational procedures and will meet the intent of Regulatory Guide 1.108.it f ( The diesel engine combustion air intake and exhaust system is not provided with any interlocks.

ATTACHMENT 10 Outstanding Issue ll(f): FSAR Section 8.3 states that in the event of a loss of offsite power (LOOP) the diesel generator roon ventilation system must be manually reconnected to the bus. The diesel generator roan ventil ation system provides cooling to the diesel generator and its auxili ary equipment during diesel generator operation. Failure to restore the ventil ation system to operating condition within a reasonable amoun t of time will resul t in diesel generator roon temperatures exceeding the 120 F design ambient temperature specified in FSAR Section 9.5.4. In a response to the staff's request for infonnation on this aspect of the design, the appli-cant stated that " operation of the primary and secondary supply fans, nonnal exhaust fans, and associated motorized dampers is maintained during loss of nonnal station power by automatic connection to the emergency bu ses." However, FSAR Table 8.3-3, " Emergency Diesel Generator Loading," only shows that the supply of fans and heaters are connected to the buses and not the other equipment.

Response

Table 8.3-3 is being revised to reflect the present loading which includes the nonnal exhaust fan (2HVD*FN222A), the primary supply fan (2HVD*FN-270A), and the secondary supply fan (2iiVD* FN271 A). These loads have been included in the existing diesel loading calculation. The associated motor operated dampers (2HVD* MOD 21 A, 22A, 23A) are fed fran a 120 V ac distribu-tion transfonner (TRF*PWR-ET ). The table does not indicate individual loads at the 120 V level. Instead, they are included in the total load indicated for the relevant distribution transfonner (TRF*PWR-El in this case). i

ATTACHMENT 11 Outstanding issue 12(a): Ins pect ion of the ext ract ion steam valves is needed to ensure that the check valve closing mechanism travels in the closing direction in a free and positive manner. This is to alleviate the concern of a turbine over-speed resulting from back flow of steam from extraction feedwater heaters. In Amendment 8 of the FSAR, the applicant described the inservice inspec-tion program for the mechanical and backup overspeed trips only.

Response

The BVPS Operating Manual requires all extraction steam noneeturn valves to have been tested within one week prior to each turbine startup. This test consists of a visual verification of valve stroking in a test latch / unlatch sequence. DLC operating experience has shown this testing is adequate to assure stable turbine speeds following a trip.

r. ATTACHMENT 12 Unnumbered Outstanding Issue (Pages 9-74 and 9-75): provided to ' automatically start and stop each air Automatic controls are . compressor when the pressure in its respective air receivers decreases or increases to predetermined leve ls. The applicant has not provided the requested setpoints for the compressor cutin and cutout pressures as well .as the high pressure, low pressure, and low-low pressure alarm setpoints.

Response

.Thse values are provided in FSAR-Table 9.5-10. No high pressure ~ or low-low pressure alarms are used at BVPS-2.

7. ATTACHMENT 13 Backfit Issue 14 : DLC was requested informally by PSB to discuss checks and/or tests including frequencies, which assure adequate air dryer performance.

Response

Pe rf o rmance of the air drye rs is assured by routine daily checks by the operators and a maintenance program based upon vendor recommendations a n.1 included in approved plant procedures. The BVPS-2 s urve illa nce s will include: L) a daily blowdown of each diesel generator's air receivers and not ing of any water vo lume obtained and 2) performance of maintenance s urve illa nce procedures at each refueling outage to inspect the air start solenoid valves. In addit ion, an alarm is provided which alerts the control room operators to a "high dewpoint tempe r atur e." This alarm is annunciated and the operator will respond as directed in the approved alarm res ponse procedure. 1 ) l l}}
