SAFETY EVALUATION AMENDMENT NO. 2 TO DPR-80 DIABLO CANYON UNIT 1 DOCKET NO. 50-275 INTRODUCTION The Technical Specifications for Diablo Canyon Unit 1 full-power operation were issued on November 2, 1984, as Appendix A to the Unit 1 Operating License DPR-80 (Ref. 1). The Technical Specifications for Diablo Canyon Unit 2 low-power operation were issued on April 26, 1985, as Appendix A to the Unit 2 Operating License DPR-81 (Ref. 2).
In May 1985 the staff identified a number of Unit 2 Technical Specifications that required further resolution for full-power opera-tion (Ref. 3).
The staff and PG&E have been pursuing the development of common and combined Technical Specifications for Unit 1 and Unit 2 since late 1984. Diablo Canyon Unit I and Unit 2 are nearly identical. There are some differences due to the mirror image, unit-specific layout, core thermal ratings, and equipment ratings.
The controls for both units are located in one common control room. As stated in SSER 31, the operating staff will be licensed on both units, with a desig-nated crew assigned and dedicated to each unit on each shift. PGAE concluded that the Technical Specifications for both units can and should be identical to a great extent. Accordingly, PG&E proposed one set of Technical Specifications, comen to both units, with unit-specific specifications due to differences in l
design and operations appropriately identified.
UNIT 1 TECHNICAL SPECIFICATION CONSIDERATIONS In January 1985 PG&E submitted License Amendment Request LAR 85-01 (Ref. 4) for Unit I to include the Unit 2 specific Technical Specifications information and make changes necessary for a two unit operation (i.e., minimum shift crew composition and diesel generator surveillance requirements).
The changes neces-sary for two unit operation were issued on April 26, 1985 as Amendment I to the Unit I license (Ref. 16). PG&E subsequently subnitted further chances to the Unit 1 Technical Specifications in Revisions 1 through 4 of LAR 85-01 to include Radiological Effluent Technical Specifications (RETS) and Diesel Fuel Oil Speci-fications, make typographical, editorial and similar type changes, improve con-sistency within the specifications, and to further update the specifications with common and unit-specific information (Ref. 5 through Ref. 8). PG&E requested further changes to the Technical Specifications for both units in LAR 85-03 regarding movable control assemblies (Ref. 8), LAR 85-04 regarding reactor trip system instrumentation (Ref. 9) and LAR 85-06 regarding a reor-ganization of the PG&E Nuclear Power Generation organization (Ref.11).
- Finally, in LAR 85-05 (Ref.10) and LAR 85-07 (Ref.12 and 13) PG&E requested Unit 1 Technical Specifications changes as a result of certain issues that had been raised by the staff with regard to full-power operation of Unit 2 (Ref. 3).
The above Technical Specifications changes for Unit I have been evaluated by the staff and are being issued as an amendment to the Unit 1 operating license DPR-80. We expect to issue the Unit 2 full-power license shortly with the same Technical Specification provisions. These changes will revise the current Unit 1 Technical Specifications to be identical to those to be issued with the W M PJ$p P
Unit 2 full-power license with unit-specific information clearly identified.
These combined and common Technical Specifications will apply to both units.
i UNIT 2 TECHNICAL SPECIFICATIONS CONSIDERATIONS By letter dated May 14, 1985, PG&E submitted License Anendment Request LAR 85-02 (Ref. 8) which provided a proposed common set of Technical Specifications in the form of a marked up copy of the Technical Specifications for Unit 2 low-power operation. The staff has reviewed these proposed changes and concludes that they will improve the overall effective use of the specifications and will identify appropriate Unit 1 specific information in the common and combined full power Technical Specifications.
The staff addressed the matter of common and combined Technical Specifications in a letter to PGAE, dated May 15,1985 (Ref. 3).
In the letter the staff requested also further consideration of 17 issues that had been identified dur-ing the preparation of the Technical Specifications for the Unit 2 low-power license. The staff met with PG&E on May 15, 1985 to discuss the issues (Ref. 20),
and PG&E provided additional information (Ref.10, and 15). The staff reviewed the infnrmation and discussed further these issues with PG&E. As a result, these issues were resolved, appropriate Technical Specifications were developed, and will be included in the common and combined Technical Specifications for both units except as follows.
The final resolution for five speciiications was achieved after the required Federal Register Notice for the Technical Specifications changes for the Unit 1 i
license amendment had been prepared (Ref. 21) as discussed under Unit 1 Technical Specification considerations above.
The five specifications are:
(1) administrative controls for startup test reports (2) reactor coolant system relief valves (3) loose-part detection system instrumentation (4) bases for electrical power systers (5) reactor coolant system pressure /6emperature limits Rather than issuing the combined Technical Specifications with substantially different requirements for Unit 1 and Unit 2 the staff determined that for an interim period the current Unit 1 Technical Specifications and Unit 2 low-power Technical Specifications, as reflected in the combined Technical Specifications, provide sufficiently conservative requirements.
PG&E, by letter dated June 20, 1985 (Ref.14) identified the resolution to the five specifications and committed 4
to submit an appropriate license amendment request for both units within 90 days after issuance of the Unit 2 full-power license. The staff finds this acceptable, As a result of its review of the Diablo Canyon Unit 1 and Unit 2 Technical Specifications, the staff determined that specifications should be included for the polar crane in the containment buildings and for the two bridge crancs in the turbine building or appropriate justification should be provided for not including them.
3 At this time, the parking location for the polar crane is restricted to pre-clude jet impingement from a postulated pipe rupture. This restriction should i
i
be included in the specifications or PGAE shall demonstrate that the crane can withstand the jet impingement forces from a postulated pipe rupture.
l The two bridge cranes in the turbine building are currently restricted by rail clamps from entering the end bays in the turbine building. The restriction for placing the two cranes relative to each other relies on visual observations imposed by administrative procedure. These restrictions should be included in the specificiations or PG8E shall demonstrate that no restriction is required.
The staff has requested PG&E to submit, in addition to the above five items, a i
license amendment request within 90 days of issuance of the Unit 2 full-power license regarding these restrictions or provide a justification why they are not required (Ref. 23). The staff finds acceptable, for the interim, the use of the current administrative procedures.
PGAE requested further changes to the current Unit I and Unit 2 Technical Specifications regarding movable control assemblies (Ref. 8), reactor trip system instrumentation (Ref. 9) and reorganization of the PG&E Nuclear Power Generation organization (Ref. 10). The staff evaluation of these proposed changes, which are applicable to both units, is presented in separate sections 1
below.
I.
MOVABLE CONTROL ASSEMBLIES 4
Introduction By letter dated May 14, 1985 PG&E requested in LAR 85-03 changes to the Techni-j cal Specification 3.1.3.1, " Movable Control Assemblies" for Diablo Canyon Units 1 and 2 (Ref. 8). The changes will allow continued operation for up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> (to perform repairs) for a condition in which there are multiple control rods which cannot be moved by their drives because of electrical power failure but which are still within alignment and trippable for insertion under gravity.
Evaluation The proposed Technical Specification changes contain Action Statements which address inoperable and misaligned movable control assemblies as follows:
Action a. is unchanged and addresses a mechanical failure of one or more full length rods that leaves the rod (s) imovable and/or untrippable.
This is the classic stuck rod situation, requiring application of the stringent fix-or-shutdown requirement.
Action b. has been deleted and replaced with the new Action c. and d.
Action c. has been relabeled to Action b. with the content unchanged and addresses one full-length rod trippable but inoperable due to causes other l
than addressed by Action a.
Action c.
A new Action c. has been added to address multiple inoperable rods and replaces the old Action b.
The change now allows operation to continue for up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> (to perform repairs) for a condition in which there are multiple imrovable rods that are still trippable and within alignment.
Action d. has been added to replace that nart of the old Action b. that j
addressed multiple misaligned rods.
l l

}
Although these Action statements have been realigned and relabeled, there is no i~
alteration of the content and requirements of the present Technical Specifications except for the new Action c.
The present Technical Specifications require the reactor to be in HOT STANDBY within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for the condition of new Action c.,
J which is when there are multiple inoperable rods which are not stuck or j
untrippable, j
l The intent and basis for Technical Specification 3.1.3.1 is to provide require-i ments which either directly in the Specification or in support of other Specifi-
]
cations ensure that:
- 1) acceptable power distribution limits are maintained, 1
- 2) the minimum shutdown margin is maintained with allowance for a stuck rod, j
- 3) the potential effects of rod misalignment on associated accident analyses i
i are limited, and 4) the trip reactivity assumed in the accident analysis will i
be available. Appropriate provisions have been made in the proposed change to j
ensure that these requirements continue to be maintained. Specifically, the
{
proposed change requires that within one hour after entering the Action state-j ment the remainder of the rods in the bank (s) with the inoperable rods are aligned to within i 12 steps of the inoperable rods. This relates to ensuring l
conformance to items 1 and 3 above.
Further, it is explicitly specified that the rod sequence and rod insertion limit Technical Specifications must be l
i l
maintained as applicable. This ensures conformance with items 2 and 4 above, t
The intent of the proposed Technical Specification change is to allow continued t
operation of the unit in the case of electrical failures which prevent moving of more than one control rod. The rods remain trippable, so they can provide their safety function in shutting down the reactor, if needed.
The staff finds the proposed change acceptable because, as indicated above, the f
safety requirements for the control rods remain intact.
Control of the power f
j plant can still be effected with boration systems, if the inoperable rods are in the control bank or the rod sequence requirements potentially could not be i
maintained.
If the first regulating banks or the shutdown banks become inoper-able while inserted in the core, the insertion limit Specification requires the power level to be 0 If the last two banks become inoperable while at part L
power the insertion limits allow operation only at 1 art power. Operation at l
{
part power or at full power with the regulating banc at its insertion limit for extensive periods of time is not accounted for in the power distribution analy-sis, which is assumed as an input condition for the LOCA analysis. Therefore the time span of the proposed change is limited to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Nonnal operation i
of the power plant assumes all of the control rods are out of the core, except the regulating bank may be inserted a small amount to allow for control of the axial flux difference and day to day reactivity burnout (which may also be controlled by boron concentration).
a In Attachment C to a letter dated December 21, 1984 from E. P. Rahe, Jr.
(Westinghouse) to C. O. Thomas (NRC), a description of the movable control I
i assembly mechanisms is provided, along with a discussion of failures which j
might occur (Ref.19). The attachment provides guidance on the type of elec-j trical failures which may render contrcl assemblies inoperable but still i
trippable.
It will be used in the preparation of the bases of the Technical
}
Specifications.
i In preparing the proposed change, PGAE also deleted the words " step counter" from the Unit 1 Technical Specifications to be consistent with Unit 2 and to i
1
allow othtr means for detemining group demand position to satisfy this Specifi-cation. Tais change is also acceptable because it does not alter the require-ment for the Specification, but only allows the possibility of other means for determining the group demand position.
II. REACTOR TRIP SYSTEM INSTRUMENTATION
Background
On February 21, 1985, the NRC issued its Safety Evaluation Report on the Westinghouse Technical Specification Optimization Program for increased sur-veillance intervals and out-of-service times for testing and maintenance of the reactor trip system (RTS) (Ref. 17). The Optimization Program proposal was set forth in WCAP-10271, " Evaluation of Surveillance Frequencies and Out-0f-Service Times for the Reactor Protection Instrumentation System" Supplement 1 (Ref.18).
By letter dated May 20, 1985, PG&E Company submitted prnposed Technical Specifi-cations as LAR 85-04 for Diablo Canyon Units 1 and Unit 2 based on the Optimiza-tion Program (Ref. 9).
Evaluation The proposed Technical Specification changes include an increase in the sur-veillance interval of reactor trip system channels from monthly to quarterly.
The proposed quarterly surveillance intervals are annotated to indicate that the quarterly tests are to be performed on a staggered test basis.
In addition the surveillance intervals for those reactor trip sytem channels which also provide signals to the Engineered Safeguards Actuation System (ESFAS) have been annctated to indicate that the more restrictive ESFAS surveillance requirements apply to these channels. These changes are consistent with the staff's generic evaluation of the Optimization Program and are, therefore, acceptable.
The surveillance frequency for channels which would be tested prior to plant startup was noted as prior to startup in lieu of quarterly as recommended under the Optimization Program. Also, the startup surveillance was annotated to indicate that it is to be perfomed prior to startup if not perfomed in the previous 31 days.
The channels for which testing prior to startup applies are:
A.
Power Range, Neutron Flux, Low Setpoint The low setpoint channels are required to be tested prior to entry into Mode 2 and for operation in Mode 1 below the P-10 interlock setpoint.
For these tran-sitional operating modes, the surveillance test would be conducted prior to startup and not on a routine basis as would be implied by specifying a quarterly test frequency. Thus, the surveillance frequency is noted as prior to startup, S/V(1).
In the Table 4.3-1 Notation, note (1) is revised to indicate if not perfomed in the previous 31 days, instead of 7 days.
B.
Intermediate Range, Neutron Flux The intemediate range channels are required to be tested for the same transi-tional modes as the power range low setpoint channels. On the same basis the surveillance frequency is noted as prior to startup, rather than quarterly, t
C.
Source Range, Neutron Flux The source range channels are required to be tested in Mode 2 below the P-6 interlock setpoint and in Modes 3, 4, and 5.
The source range channels, in addition to initiating reactor trip, provide the high flux alarms at shutdown which alert the operator of reactivity changes caused by a boron dilution i
event. Therefore, the surveillance requirements for the source range channels apply to Modes 3, 4, and 5.
The surveillance frequency is noted as prior to i
startup and as quarterly.
D.
Reactor Trip System Interlock (RTSI), Intermediate Range Neutron Flux, P-6 The P-6 interlock channels are required to be tested prior to entry into Mode 2 and for operation in this mode below the P-6 interlock setpoint.
For this transitional operating mode, the surveillance test wculd be conducted prior to startup and not on a routine basis as would be implied by specifying a quarterly test frequency. Thus, the surveillance frequency is noted as prior to startup.
E.
RTSI, Low Power Reactor Trips, Pleck, P-7 The surveillance frequency is noted as prior to startup, consistent with that specified for the P-10 and P-13 channels as noted below, a
F.
RTSI, Power Range Neutron Flux, P-8 The currently specified monthly test interval is annotated to indicate that l
when the plant is at a power level greater than the channel trip setpoint, the surveillance requirement is satisfied by verifying that the interlock permissive logic is in its required state. This provision was included in the Technical Specifications such that power reductions below the channel setpoint would not be required for the sole purpose of meeting the surveillance requirement.
For i
example, the previous monthly surveillance requirement for the P-8 channels would require a power reduction below its setpoint had this annotation to the surveillance requirement not been included. Likewise, this same annotation is used for the P-10 channels and precludes the necessity of power reductions for testing.
l This annotation to the surveillance requirement only verifies the status of the permissive logic and does not address verification of channel setting or oper-ability. Those aspects would be verified following a refueling shutdown and prior to startup. With a monthly surveillance interval the annotated surveil-lance at power would in all likelihood have expired during a refueling shutdown (i.e., exceeded 31 days) and testing would be required prior to entry into Modes 2 or 1, as applicable to the permissive channels. However, this situation may not be true if a quarterly surveillance interval is specified, i.e., the annotated surveillance perfomed at power may not have exceeded a 92 day sur-veillance interval during a refueling shutdown. Therefore, since the only comprehensive tests are actually performed prior to startup, the surveillance interval is stated as prior to startup.
The status of interlock permissives at the logic and channel level are individ-ually indicated on status monitoring displays in the control room. As such they are routinely checked and particular attention is given to this infomation i
during operational mode changes. The fact that the permissive status indication is readily available and can be routinely verified constitutes a different con-sideration with respect to the availability of trip channels which must change state on the occurrence of an event and for which the function unavailability is dependent on the surveillance interval.
It is concluded that maintaining the requirement for the verification of the permissive logic status is not safety significant. Therefore, since the surveillance frequency has been noted prior to startup, note (8) is no longer applicable to these channels.
G.
RTSI, Low Setpoint Power Range Neutron Flux, P-10 The surveillance frequency is noted as prior to startup, on the same basis as for the power range P-8 channels noted above.
H.
RTSI, Turbine Impulse Chamber Pressure, P-13 The surveillance frequency is noted as prior to startup. The bases with regard to note (8) is the same as for the power range interlock channels noted above.
However, unlike the power range channels which can only be tested when the measurement signal is below the setpoint, the turbine impulse chamber pressure channels include features which would permit them to be tested without reducing reactor power. However, since the P-13 channels and hence P-13 logic only pro-vide inputs to the P-7 logic which are diverse to the P-10 inputs to the P-7 logic, it is concluded that there is sufficient justification for excluding testing as currently noted by the provision on note (8) when operating above the P-13 setpoint. Further, since the channel state is indicated, its state can be readily determined. Thus, it is concluded that the additional surveil-lance as would occur by noting a quarterly surveillance frequency annotated with note (8) is not warranted.
By letter dated July 18, 1985, PG&E requested a change to exclude the require-ment to test the P-13 channels prior to startup from Modes 2 or 3 (Ref. 22).
A startup from Mode 2 (power less than 5 percent) or from Mode 3 (not standby) would occur only following plant operation at power and subsequent reduction in power to these modes. Such plant startup would be due to unusual circum-stances and not on a routine basis.
It is concluded that this change is accept-able since the additional testing which may result under these conditions would not have an impact on plant safety due to considerations related to the operability of interlocks noted above. This exception to the startup tests is included as " Note 8" to the surveillance requirements.
With regard to the inclusion of the startup test requirement, wherein channels would be tested prior to plant startup if not tested in the previous 31 days, the staff concludes that this is appropriate in view of the increase in the surveillance frequency from that currently required for startup tests if not performed in the previous 7 days.
I.
Out of Service Times for Testing and Maintenance For those RTS channels which provide input signals to ESFAS, the ACTION column of Table 3.3-1 is annotated, as applicable, with note (1) and the Table 3.3-1 notation includes note (1) to indicate that the applicable Modes and ACTION statement for these channels under the ESFAS specification requirements are applicable. This is consistent with the staff's evaluation for the Optimization Program and is, therefore, acceptable.
Conclusion The staff concludes that the proposed Technical Specifications are acceptable for Diablo Canyon Units 1 and 2.
III. GONPRAC COMPOSITION PG&E requested in License Amendment Request LAR 85-06 of May 30, 1985 (Ref. 61), changes to the Technical Specifications for Diablo Canyon Units 1 and 2.
The LAR proposes to change the composition of the PG&E General Office Nuclear Plant Review and Audit Committee (GONPRAC) to reflect changes to the PG&E Nuclear Power Generation Department. These organizational changes have been reviewed by the staff during the full-power license review for Diablo Canyon Unit 2 and were found acceptable.
The proposed changes to the composition of the GONPRAC delete two members (i.e., Project Manager - Diablo Canyon, and Technical Assistant to the Vice President - Nuclear Power Generation) and add three new members (i.e., Manager
- Nuclear Engineering and Construction Services, Director - Nuclear Administra-tion and Support Services, and Director - Nuclear Regulatory Affairs).
The staff finds that the proposed changes meet the acceptance criteria of Section 13.4 of NUREG-0800, the Standard Review Plan, and concludes that the changes to the composition of the GONPRAC are acceptable.
IV. RADIOLOGICAL EFFLUENT TECHNICAL SPECIFICATION Introduction PG5E has filed with the Comission plans and proposed Radiological Effluent Technical Specifications (RETS) developed for the purpose of keeping releases of radioactive materials to unrestricted areas during normal operations, specifications would reasonably assure compliance, in radioactive waste management, with the provisions of 10 CFR Part 50.36a, as supplemented by Appendix I to 10 CFR Part 50, with 10 CFR Parts 20.105(c), 106(g), and 405(c);
with 10 CFR Part 50, Appendix A, General Design Criteria 60, 63, and 64; and with 10 CFR Part 50, Appendix B.
Background and Discussion NUREG-0472 provides radiological effluent technical specifications for pressurized water reactors which the staff finds to be an acceptable standard for licensing actions.
Further clarification of these acceptable methods is provided in NUREG-0133, " Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants." NUREG-0133 describes methods found acceptable to the staff of the NRC for the calculation of certain key values required in the preparation of proposed radiological effluent technical speci-fications for light-water-cooled nuclear power plants. NUREG-0133 also provides guidance to licensees in preparing requests for changes to existing radiological effluent technical specifications for operating reactors.
It also describes current staff positions on the methodology for estimating radiation exposure due to the release of radioactive materials in effluents and on the administrative control of radioactive waste treatment systems.
The above NUREG documents address all of the radiological effluent technical specifications needed to assure compliance with the guidance requirements provided by the regulations previously cited. However, alternative approaches
-9_
l 4
to the preparation of radiological effluent technical specifications and alternative radiological effluent technical specifications may be acceptable if the staff determines that the alternatives are in compliance with the regulations and with the intent of the regulatory guidance.
J Plant Specific Background i
In three different submissions (Ref. 4, 5, 6) PG&E has formally requested i
Technical Specification changes that would upgrade the Diablo Canyon-1 RETS i
to be in conformance with the latest NRC staff positions. The first submission j
was used as the starting point for the development of acceptable RETS for j
Diablo Canyon-2. After a number of discussions between PG&E staff and NRC staff a final set of RETS was developed for Diable Canyon-2 which met the 2
intent of current NRC guidance. These RETS were included as part of the published Diablo Canyon-2 Technical Specifications (Ref 2).
Partway through this development for Diablo Canyon-2, PG&E made a second RETS i
submission for Diablo Canyon-1 that contained some of the original markup i
pages from the earlier submission, and some of the retyped pages from the J
Diablo Canyon-2 RETS that were in process.
Further discussion with PG&E resulted in an agreement to make a final i
submission for Diablo Canyon-1 once the Diablo Canyon-2 RETS had been j
accepted technically.
s
~
PG&E then formally submitted on April 24, 1985 (Ref. 6) proposed changes to
(
their RETS for Diablo Canyon Unit I to make them consistent with the RETS for l
]
Diablo Canyon Unit 2, which in turn have been developed to be consistent with current regulatory guidance.
1i Evaluation The proposed changes to the Diablo Canyon Unit 1 RETS as presented in the April 24, 1985 submission were found to meet the intent of the NRC staff's model RETS for PWRs, NUREG-0472, Revision 2, February 1,1980, and therefore e
i are acceptable.
t Sumary I
The proposed changes to the radiological effluent technical specifications for a
Diablo Canyon Unit I h u e been reviewed, evaluated, and found to be in compliance l
with the requirements of the NRC regulations and with the intent of NUREG-0133 and NUREG-0472 (Diablo Canyon Unit 1 is a pressurized water reactor) and thereby fulfill all the requirements of the regulations related to radiological effluent technical specifications.
The' proposed changes will not remove or relax any existing requirement needed i
to provide reasonable assurance that the health and safety of the public will i
not be endangered by operation in the proposed manner. The staff, therefore, finds the proposed changes acceptable.
V.
AUXILIARY FEEDWATER SYSTEM In SSER No. 4, the staff identified the need for technical specifications to s
j limit the steam generator refill rate via the auxiliary feedwater system in i
l
)
_ to _
order to further limit the potential for adverse (damaging) feedwater hamer.
Since issuance of SSER No. 4 (May 1976), the staff has completed generic i
studies of waterhammer concerns including resolution of USI A-1 and has com-pleted study of auxiliary feedwater system reliability in connection with Item II.E.1.1 of the TMI-2 Task Action Plan, NUREG-0737. Based on the results of this work, we now conclude that throttling auxiliary feedwater flowrate to limit steam generator level recovery as a means of reducing waterhamer poten-tial is no longer necessary or desirable. Preoperational testing at Diablo i
Canyon Unit 1 as well as operating experience at other Westinghouse reactors has shown that modifications to the feedring and revised plant operating pro-cedures have effectively limited waterhamer was rereviewed with an intent i
to eliminating it in order not to adversely affect auxiliary feedwater reliability as indicated in the implementation of Item II.E.1.1 of NUREG-j 0737 (Recommendation GS-3). Diablo Canyon was previously reviewed against this recommendation and found acceptable.
l Based on the above, we conclude that technical specification to limit steam generator refill rate are not necessary for Diablo Canyon Units 1 and 2, as i
suitable measures for limiting feedwater hamer via the auxiliary feedwater system are provided.
VI. DIESEL FUEL OIL SURVEILLANCE RE0VIREMENTS In letters dated January 30, March 13, and May 14, 1985, (Ref 4, 5, 6) Pacific Gas and Electric Company proposed changes in the diesel fuel oil surveillance i
requirements (Technical Specification 4.8.1.1.2.d and 4.8.1.1.3) for Diablo Canyon Unit 1.
The proposed changes will result in the Diablo Canyon Unit 1 1
Technical Specifications being consistent with the Diablo Canyon Unit 2 j
Technical Specifications.
1 In general, the proposed changes involve replacing the diesel fuel oil tests presently required by the Technical Specifications with the McGuire Tests that (1) are more effective in detecting unsatisfactory fuel oil, (2) can be performed onsite, and (3) are simpler to perform. The McGuire Units 1 and 2 Technical Specifications surveillance requirements were approved on June 5, i,
1984. The effectiveness of the McGuire Technical Specifications is based upon j
the ability to remove all the water that may accumulate in fuel oil storage on a 31 day frequency. The Diablo Canyon fuel oil storage tanks were evaluated on this basis.
In a letter dated March 13, and May 14, 1985 (Ref. 5,6), PG&E submitted information on the fuel oil storage tank design with regards to water removal capability and the commitment to remove the water on a 31 day frequency. The 4
staff has evaluated the information and finds that the design of the fuel oil i
storage tanks allows for the removal of essentially all the water that may accumulate in the tank. The removal of accumulated water from the storage tanks every 31 days will reduce the possibility of bacteria contamination of the stored fuel, minimize the formation of corrosion products, and prevent water from contaminating the diesel generator fuel oil system.
The proposed changes to the present surveillance requirements for diesel fuel 4
oil in Technical Specification 4.8.1.1.2.d and 4.8.1.1.3, as proposed by PG8E for Diablo Canyon Unit 1, will result in a more conservative approach
.I
to fuel oil surveillance. The added conservatism coupled with the simplified testing of fuel oil will provide immediate assurance in acceptance of quality fuel oil on delivery and maintenance of high quality stored fuel; this should increase diesel generator availability. Therefore, the proposed Technical Specifications changes to the diesel fuel oil surveillance are acceptable.
VII. THERMAL HYDRAULIC DESIGN EFFECT OF FUEL ROD B0 WING ON DNB In Diablo Canycn SER Supplement #6, the staff stated that as an interim measure, we will include a burnup dependent penalty factor to be applied i
to the reactor operating limits in Section 3.2.3 of the Technical Specifi-cations to reflect the reduced DNB conditions caused by increasing fuel rod bowing.
Subsequent to issuance of the SER Supplement, the Westinghouse tropical report WCAP-8691, Revision 1, " Fuel Rod Bow Evaluation", has been approved by the staff. This rod bow penalty evaluation method applies statistical convolution of the critical heat flux test data and interfuel rod gap closure data to derive the rod bow penalty on DNBR. The use of this method results in a significantly lower rod bow penalty compared to the interim method previously used.
PG&E has submitted a table of rod bow penalty as a function of fuel burnup calculated with the approved Westinghouse method.
Since rod bow and gap closure increase with fuel burnup, the rod bow penalty on DNBR increases with burnup. However, even though the plant may be operated at higher burnup, the maximum fuel burnup used for the rod bow penalty calculation is 33, 000 MWD /MTU. The reason for using 33,000 MWD /MTU as a cutoff paint is because the physical burndown effect of the high peaking fuel rod will exceed a burnup of 33,000 MWD /MTU, it is not capable of achieving limiting peaking factors due to the decrease in fissionable isotoper and the buildup of fission product inventory. Therefore, the rod bow penalty value of less than 3%
DNBR at 33,000 MWD /NTU represents the maximum rod bow penalty for Diablo Canyon plants having 17x17 R-Grid fuel assemblies.
However, credit is available to offset this rod bow DNBR penalty. The generic margin (credit) totaling 9.1 percent DNBR is derived from the difference between the design and required values on the following items:
(a) design DNBR limit, (b) grid spacing multipliier coefficient, (d) DNBR spacer factor multiplier and fe()c) thermal diffusion pitch reduction.
Since the rod bow penalty is completely compensated by the available margin of 9.1 percent, no penalty is required in the reactor operating limit. We have incorporated this rod bow penalty compensation in the bases of the Diablo Canyon Technical Specifications.
VIII. ADDITIONAL UNIT I TECH SPEC CHANGES NECESSARY FOR COMBINED UNIT 1 & 2 TECHNICAL SPECIFICATIONS Introduction In accordance with the licensee's applications for amendment dated May 14 (LAR 85-01, Rev. 4 and LAR 85-03), May 20 (LAR 85-04), and May 30, 1985 (LAR 85-05 and LAR 85-06), Ref. (8, 9, 10) the proposed changes would revise the Diablo Canyon Unit 1 Technical Specifications to eliminate typographict..
errors, provide additional clarifications, improve consistency, adjust nomen-clature, modify the reporting requirements to bring then into confonnance with the guidance in Generic Letter 83-43 for the Licensee Event Report System, bring portions of the Specifications into conformance with current NRC staff positions, incorporate Unit 2 information where appropriate, and make other minor changes. A primary objective of the amendment request is to achieve a single Technical Specifications document that is connon for the nearly identical Units 1 and 2 with individual specifications for each unit clearly identified as appropriate.
In this regard, the proposed changes to the Unit 1 Technical Specifications are consistent with the Unit 2 Technical Specifications recently issued as Appendix A to Facility Operating License DPR-81 and proposed changes to the Unit 2 Technical Specifications included in the licensee's application for amendment to DPR-81 dated May 14, 1985. Furthermore, most of the Unit 1 proposed changes have already been incorporated by the Connission into the current Unit 2 Technical Specifications as a part of DPR-81. This becomes a pertinent consideration in evaluating whether or not the Unit 1 proposed changes involve a significant hazards consideration. Discussed below are the various types of changes to the Technical Specifications.
A.
Administrative Changes to Technical Specifications The proposed changes in the Unit 1 Technical Specifications for the items listed below are provided to eliminate typographical errors, correct punctuation, adjust nomenclature, add clarification, improve consistency, make minor changes, and include Unit 2 Speci-fications as necessary to reflect operation of Units 1 and 2.

4 The proposed changes have already been incorporated by the Comission into the current Unit 2 Technical Specifications. The staff has reviewed these changes and finds that incorporation of these same changes into Unit 1 Technical Specifications will upgrade the specifications for Unit I and make the Unit 1 Technical Specications essentially equivalent in tems of content, style and format. Based on the staff review, wr find that the changes confom to the regula-tions and are, there, acceptable.
SUMARY AND CONCLUSIONS PG&E submitted a number of license amendment requests for changes to the Techni-cal Specifications for the Unit 1 full-power license and the Unit 2 low-power license in order to (1) establish common and combined Technical Specifications for both units (2) make editorial and fonnat changes (3) revise the specifications for movable control rod assemblies, reactor trip system instrumentation, PG&E General Office Nuclear Plant Review and Audit Comittee (GONPRAC) composition, Radiological Effluent Technical Specifi-cation, auxiliary feedwater system, diesel-fuel oil surveillance require-ments, and thermal hydraulic design effect of fuel rod bowing on DNB.
f (4) resolve certain full-power considerations that had been identified by the staff during the Unit 2 low-power licensing.
Based on the staff review of the infonnation provided by PG&E and based on further discussion with PG&E the staff has developed common and combined Technical Specifications for Units 1 and ? that include the above considera-tions. The Technical Specifications for six issues identified under Unit 2 Tech Spec considerations will be revised BY LAR for both units after issuance of the specifications.
. r,.
CONTACT WITH STATE OFFICIAL The NRC staff has advised the Chief of the Radiological Health Branch, State Department of Health Services State of California, of the proposed determina-tions of no significant hazards consideration. No coments were received.
ENVIRONMENTAL CONSIDERATION This amendment involves changes in administrative procedures and requirements and in the installation or use of facility components located within the re -
stricted area, respectively. The staff has determined that the amendment involves no significant increase in the amounts of any effluents that may be released offsite and that there is no significant increase in the individual or cumulative occupation radiation exposure. The Comission has previously issued proposed findings that the amendment involves no significant hazards consideration, and there has been no public coment on such findings. Ac-cordingly, the amendment meets the eligibility criteria for categorical exclu-sion set forth in 10 CFR Sec. 51.22(c)(9) and (10).
Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
CONCLUSION Based upon our evaluation of the proposed changes to the Diablo Canyon, Unit 1 Technical Specifications, we have concluded that:
there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and such activities will be conducted in compliance with the Cornission's regulations and the issuance of this amendment will not be inimical to the comon defense and security or to the health and safety of the public.
