LINE-lTEM TECHNICAL SPECIFICATION IMPROVEMENTS TO REDUCE SURVEILLANCE j REQUIREMENTS FOR TESTING DURING POWER OPERATION (Generic Letter 93- ). j The staff of the U.S. Nuclear Regulatory Commission (NRC) has completed a com-l prehensive examination of technical specification (TS) surveillance require-i ments that require testing during power operation. This effort is a part of the NRC Technical Specification Improvement Program (TSIP). The results of 7 this work are reported in NUREG-1366, " Improvements to Technical Specifications Surveillance Requirements," December 1992. NUREG-1366 is available for } i examination in the NRC Public Document Room, 2120 L street, NW, Lower Level, j Washington, DC 20S55 and for purchase from the GPO Sales Program by writing to i the Superintendent of Documents, U.S. Government Printing Office, P.O. Box 37082, Washington, DC 20013-7082. In performing this study, the ii staff found that while the majority of the testing at power is important, s safety can be improved, equipment degradation decreased, and an unnecessary .[ t burden on t.ersonnel resources eliminated by reducing the amount 'of testing that i i' the TS require at power operating conditions. However, only a small fraction. i of the TS surveillance intervals was considered to warrant relaxation. The staff has prepared the enclosed guidance to assist licensees in preparing a ' i l license amendment request to implement these recommendations as line-item TS i improvements. The NRC issued improved standard technical specifications in i September 1992 that incorporated the recommendations of NUREG-1366. [ i; l 1 r i

The NRC project managers will review l 1 f requests for license amendments to verify that they conform to this guidance. Please contact the project manager or the contact indicated below if you have f questions on this matter. ) l Any response to the suggestion that licensees or applicants propose these TS j changes is voluntary. Therefore, any action taken in response to the guidance 'f i provided in this generic letter is not a backfit under Section 50.109 of Title 10 to the Code of Federal Reaulations (10 CFR 50.109).

l GUIDANCE FOR IMPLEMENTING LINE-ITEM TECHNICAL SPECIFICATI0N' IMPROVEMENTS TO REDUCE TESTING DURING POWER OPERATION i

INTRODUCTION This enclosure provides guidance for preparing a license amendment request to l change the technical specifications (TS) to reduce testing during power opera-i tion. These line-item TS improvements are based on the recommendations of an NRC study that included a comprehensive examination of surveillance require-j ments and is reported in NUREG-1366, " Improvements' to Technical Snecifications Surveillance Requirements." i Each of the applicable NUREG recommendations is addressed herein with examples i of TS changes based upon standard technical specification (STS) requirements f that were used as model TS when many plants obtained their operating license. The title and number of each of these line-item improvements corresponds to.the section title and number in NUREG-1366 in which the staff recommended the l change The staff is providing the NUREG recommendation for each item, but the ); NUREG finding is provided only where it is necessary to clarify the intent of l l the NUREG recommendation. The staff is providing the wording for the changes } to specific TS sections using the noted model STS requirements, with the l.i reactor vendor identified in brackets and noted as "(Typ)" where it.is typical l of the change that applies to the TS for reactors of more than one type or l vendor. The staff is providing the wording for a few of the recommendations from TS changes that have been approved for a specific plant. In this case, t I l I

> the plant is identified in brackets as the source of the guidance. The proposed TS changes for plants that have TS in a format that is different than the STS should be consistent with the intent of the NUREG recommendation, the enclosed guidance, and the format of individual plant TS. COMPATIBILITY WITH OPERATING EXPERIENCE Licensees should not propose changes to extend any surveillance interval if the recommendations of NUREG-1366 are not compatible with plant operating exper-ience. Therefore, each licensee should include a statement in the license amendment request that all proposed TS changes are compatible with plant operating experience and are consistent with this guidance. LINE-ITEM TS IMPROVEMENTS 4.1 Moderator Temoerature Coefficient Measurements (pWR) Findings: (1) Technical Specifications require a determination of moderator temperature coefficient at 300 ppm boron concentration. (2) If measured moderator temperature coefficient is more negative (less conservative than the TS value), the licensee must measure the moderator temperature coefficient every 14 EFPDs until the end of the cycle. (3) Measuring the moderator temperature coefficient at low boron concentrations is difficult. (4) VEPC0 [ Virginia Electric Power Company] proposed a method for eliminating this requirement

~ t- - T -l below 60 ppm. (5) Method is plant-specific. l l t Recommendation: Other licensees may wish to use the VEPC0 approach. li i i The following condition must be met and addressed to justify the use' of the 'l VEPC0 approach: 1 Results of plant-specific analysis are required that show that the maximum l; rassible change in moderator temperature coefficient (MTC) from 60 ppm to j the end of the operating cycle (EOC) is less than the difference:in the values of MTC from 60 ppm to EOC HTC that are specified in this Technical Specification. } 3/4.1 Reactivity Control Systems - Moderator Temperature Coefficient, l [W STS (Typ)] TS 4.1.1.3: j The MTC shall be determined to be within its limits during each fuel cycle f as follows:

]

t The MTC shall be measured and compared to the BOL limit specification a. 3.'..l.3a., above, prior to initial operation above 5% of RATED i THERMAL POWER, after each fuel loading; and b. The MTC shall be measured at any THERMAL POWER and compared to -{3.0]. l ? x 10-4 delta-k/k/ degree-F (all rods withdrawn, RATED THERMAL POWER [ t condition) within 7 EFPD after reaching an equilibrium boron concen-I f i r ~

1 tration of 300 ppm.*, In the event this comparison indicates the MTC i is more negative than -[3.0] x 10-4 delta-k/k/ degree-F, the MTC shall be measured, and compared to the E0C MTC lir,it.of Specification i l 3.1.1.3b., at least once per 14 EFPD during the remainder of the fuel j t

cycle, j

i

  • Once the eouilibrium boron concentration (all rods withdrawn. RATED i

THERMAL POWER condition) is 60 com or less. further measurement of the MTC I may be suspended if the measured MTC at an eouilibrium boron concentration ) of 60 ppm or less is less neaative than Ithe credicted value of MTC at ? a 60 onml. i (Footnote added to be consistent with recommendation.) l 4.2 Control Rod Movement Test ~ 4.2.1 Pressurized Water Reactors t I Recommendation: Change frequency of the PWR control rod movement test to quarterly. 1 l1 3/4.1.3 Movable Control Assemblies, [W STS (Typ)] TS 4.1.3.1.2: I' Each full-length rod not fully inserted in the core shall be determined to be OPERABLE by movement of at least 10 steps in any one direction at least { once per 92 days. f ? 4 'i

f ~ i 3 h _.5-(Replaced "31" with "92" days.) l 4.2.2 Boilina Water Reactors -l a ' i Recommendation: The TS should be changed to require that.if a con - i trol rod is immovable because of' friction or mechanical interference, f the other control rods should be tested within 24 hours and every l 7 days thereafter. (NOTE: Existing TS requirements include testing control rods every 7 days. Therefore, the recommendation to change j t the frequency for tests that apply when a control rod is immovable'to j i include "once every 7 days thereafter" is already covered by the i existing requirements that apply before the occurrence of an -[ immovable rod as noted in item a below.)' 3/4.1.3 Control Rods, [BWR/6 STS (Typ)] TS 4.1.3.I'2: When above the low power setpoint of the RPCS, all withdrawn control rods l not required to have their directional-control valves disarmed electric-: ll ally or hydraulically shall be demonstrated OPERABLE by moving each control rod at least one notch: l a. At least once per 7 days, and t b. Within 24 hours when any control rod is immovable as a result of i excessive friction or mechanical interference.

BWR) l Findings: (1) The surveillance requirements for the control room l f emergency ventilation system contain a requirement ~that the control l room temperature be verified every 12 hours to assure that it is less i than a temperature typically in excess of 100 degrees-F. (2) This j temperature limit is to ensure equipment operability and human f habitability. It does not appear to be effective for either purpose. 1

S*: (.. - Recommendation: Replace this requirement with a more useful surveillance or delete it if a more effective limit cannot be - established. Because the burden for verifying that the control room temperature is within its limit is not believed to be significant, no change to existing TS are pro-posed in response to this recommendation.

BWR) Recommendation: (1) When a EDG itself is inoperable (not including a. l support system or independently testable component), the other EDG(s) i should be tested only once (not every 8 hours) and within 8 hours-unless the absence of any potential common mode failure can be demon-strated. (2) EDGs should be loaded in accordance with the vendor i recommendations for all test purposes other than the refueling outage LOOP tests. (3) The hot-start test following the 24-hour EDG' test should be a -simple EDG start test. If the hot-start-test is not j performed within the required 5 minutes following the 24-hour EDG test, it should not be necessary to repeat the 24-hour EDG test. The only requirement should be that the hot-start test is performed f within 5 minutes of operating the diesel generator at its continuous i i .i

.. rating for 2 hours or until operating temperatures have stabilized.

a . recommendations for changes to technical specifications. (4) Section 4.0.2 of the Technical Specifications, which allows the extension of a surveillance test interval, should be made applicable to Section 4.0.5 concerning the ASME Code testing in those Technical Specifications which presently do not allow Section 4.0.2 to be applied. 3/4.0 APPLICABILITY [All STS (Typ)] TS 4.0.5 (c): 9 (c) The provisions of Specification 4.0.2 are applicable to the above required frequencies for performing inservice inspection and testing 4 activities. For plants with custom TS, the reference to TS 4.0.2 should be replaced with the applicable TS section that allows surveillance intervals to be extended by 25 percent of the specified interval. In addition, the term "above" may be deleted from the reference to the " required frequencies for performing inser-vice inspection and testing activities." Finally, if plant TS do not include a general specification (TS 4.0.5) on inservice inspection and testing, a new numbered general specification requirement should be proposed based on the STS model specification (TS 4.0.5), or the following statement should be proposed for addition to the specification that allows surveillance intervals to be extended by 25 percent of the specified interval: i 1 i This provision is applicable to the required frequencies for performing inservice inspection and testing of ASME Code Class 1, 2, and 3 a
