Discrepancy: Pipe support Calculation NP(F)-Z19B-071 discrepancy Descripuon: We have reviewed the Pipe Support calculation No. NP(F).
Z19B-071 Rev. 5. Based upon this review we have noted the following discrepancies:
(a) On page no. 24 of the above calculation, applied forces an:1 moments are computed at center line of the splice (Point B) as follows:
Fxb = Fx/2 sides = 7,798#
Fyb = Fy/2 sides = 8,C!!#
Fzb = Fz/2 sides = 6,577#
The above forces are discrepant because they do not include the contributions from the applied moments at pipe center line.
The correct forces are as follows:
Fxb = Fx/2 sides = 7,798# ( No Change)
Fyb = Fy/2 sides + Mz / 2Lz = 9,580#
Fzb = Fz/2 sides + My / 2Lz = 7,078#
(b) On page no. 29, the allowable shear for 1" Diameter A 325 SC bolts used is 13.40 k. This is in error. The bolt allowabic shear should be based upon Shear Tension interaction for slip-critical connection per section J.3 of AISC manual,9th edition.
The correct value is 6.58k.

Discrepancy: Liner Plate Pad calculation discrepancy
Description:
We have reviewed Liner Plate Pad Calculation # 12179 SEO-v1.113,R1, Based on this review, we have noted the following discrepancy.
- 1. This calculation references Calc. # SEO- /1.088,R0 for the liner pad qualification. The FEM model used in Calc. #SEO-V1.088, page 14, conservatively specifies the attachment location at the anchor point which will produce maximum anchor load. However, this assumption would not produce maximum stress in the plate.
An evaluation of the maximum plate stress, using attachment location in the middle of the plate span, should be made to confirm that the plate stre,s is not critical.

Discrepancy: Inadequate Corrective Action - Action to prevent Recurrence
Description:
Two Condition Reports (ACR M3 96-0041, Lovel D and M3 0920, Level 2) identified the probable causes of the conditions as inadequate 10CFR50.59 Safety Evaluations. Although the technical issues were adequately resolved, in neither of these cases was the action to prevent recurrence (inadequate safety evaluations) appropriately addressed. Form RP-4-7, page 3 of 4, Causal Factor Corrective Action Plan states, " Detail those actions that havo been taken, are on-going or will be taken (near-term and long-term) that will be taken to verify the continued effectiveness of the corrective action." In neither case has the action to correct the causal factors been addressed, i.e.,
inadequate Safety Evaluations. The same applies on page 4 of for of Form RP 4-7, block 7 which requires a statement identifying, ". ..how the corrective actions will effectively prevent or reduce the possibility of the same or a similar event or adverse condition from happening again..." This section in ACR M3-96-0041 has nothing entered, while the entry for ACR M3 0920 is inadequate in that it does not describe how the correctiva action will prevent recurrence.

ACR M3-97 0327 identified an inadequacy with a calculation which was updated due to the instalation of an additional filter in the diesel air starting line The ACR identified that the calculation update did not consider the pressure drop through the after cooler, coalescing filters and the after-fitter, The discussion in the ACR also identifies that the calculation was not reviewed at the time of initiation or completion of the affected PDCR, The identified corrective action provides for redoing the calculation but does not address the programmatic issue of why rcviews were not performed.

Discrepancy: Assignment of Tech Spec Required Eq':1pment Surveillance as~
"Non-Tech Spec" Ducription: Maintenance Procedure MP 3789AA is designated as *Non-Tech Spec
- ACR 04195 was generated to address the question of whether a l surveillance was required for auxiliary building heaters. This ACR was subsequently closed on the basis that Maintenance Procedure MP 3789AA already existed to test the subject heaters.
The TRM (Technical Requirem$nts Manual) specifies requirements for entering LCOs if the subject heaters are inoperable and outside temperatures are less than or equal to 17 degrees F. Refer to OPS Form 3273-3/4.3.1.2.2 and 3/4.3.1.2.4; 3/4.3.5.2 and 3/4.3.5.3.
Documentation provided with the ACR included a June 18,1993 Memorandum that provided a surveillance procedure number (SP 3614.A4) for the new tech spec surveillance which would be generated to test the heaters, further stating that
- Engineering must determine the need for the surveillance." and
- I believe there should be one since we check heaters on the Aux. Bldg.
filters.* This new surveillance was apparently never implemented.
The ACR 04195 close out is discrepant because it does not fully address the issues raised in the ACR. Specifically,
- 1. Procedure MP 3789AA does not require the Shift Supervisor to review the test results for system operability determinathn. In absence of the shift supervisor operability determination, h is not clear how the TRM requirements to enter Tech Spec LCOs when the heaters fall the test is being ensured.
- 2. It is not clear what the justification is for not making the surveillance a Tech Spec surveillance with the attendent administrative controls for ensuring safety rela +ed equipment operability, Note that although the TPM requb s entering a Tech Spec LCO if the heaters are INOP when temperatures are below 17 degrees F, there is no reference to Tech Specs in MP 3789AA.

Discrepancy: Lower Pipe Support Stiffness Review and inspection Discrepancy
Description:
Document EMD-80 2, dated March 5,1980, contains provisions and criteria for the support stiffness values to be used in the pipe stress analysis. In order to ensure consistency between the actual support stiffness and assumptions used in the stress analyuls, Section 3.6 of the aforementioned report requires the review and inspection of pipe support configurations for cases where the support stiffness may be substantially reduced.
A sample review of the support configurations identified instances where the support stiffness is substantilly lower than the one used in pipe stress analysis. However, for these supports, the review and inspection of pipe support configurations required by EMD-80-3 is not documented in the calculations. Thus, it could not be verified whether or not the required review was performed for the following supports:
Calculation no. NP(F)-Z79B-021,Rev.6, dated 07/25/85 ; Drawing no. BZ-79R 18 Stiffness used in pipe stress analysis: k = 1000 Mn
( From Stress Report no. NP(B)-X 7920,Rev.3,CCN 7, dated:
8/27/96).
Actual (calculated) support stiffness ka = 395 k/in < 1000 k/in, Calculation no. NP(F)-Z79R-753-H002,Rev.1, dated 11/27/96 ;
Drawing no. BZ-79R 53-1 Stiffness used in pipe stress analysis: k = 200 k/in (From Stress Report no. NP(F)-961 XD,Rev.2).
Actual (calculated) support stiffness ka = 18.7 k/in < 200 k/in.

Discrepancy: FSAR Inconsistent with Calculations
Description:
A review of the following documentation has concluded that a discrepancy exists with regard to documentation relating to estimated doses in the Millstone 3 (MP3) control room following a Loss of Coolant Accident (LOCA). The documents reviewed are: "
- 2) Calculation 88-019-97RA, Rev. O, " Doses to the MP3 Control Room and Technical Support Center from a Unit 3 LOCA*
- 3) Calculation 88-019-98RA, Rev. O, ' Shine Dose to the MP3 -
Control Room and Technical Support Center from a Unit 3 LOCA' The two calculations cited above form the basis for the estimated doses to the to MP3 control room and technical support center following a design basis LOCA at MP3. A review of the reported results in FSAR Table 15.6-13 concluded that the shine dose contribution in calculation 88-019-98RA may have been omitted from the values reported in the FSAR. These values appear to have been updated in 1992 by FSAR update 92-22, but the values apparently did not reflect the shine dose -
contribution.
UIR 104 addresses a letter to the NRC that provided updated control room dose estimates, but the dose calculations referenced above were not cited.

Discrepancy: Missing Documents in Preoperational Test Package for QSS Descripuon: The preoperational test package for the Quench Spray System (QSS) requires a surveillance test (SP 331105) to document that a valid QSS ncnel air test was completed. The surveillance test documents are missing from the QSS preoperational test package.
FSAR 6.2.2.4.1 requires that
- Means are provided for periodic in-place air flow tests through the quench spray nozzles ... The test will also be performed during the final stage of preoperational testing for this system to verify that the nozzles are not plugged."
l l
Preoperational test T3309-P001, Quench Spray System, I provides the necessary acceptance criteria and direction to {
satisfy this requirement. Section 7.3 of this preoperationaltest directs that surveillance procedure SP 331105, Containment Quench Header Nozzle Flow Test, be performed to verify acceptable flow from each header nozzle, and ta include the completed procedure in the test data package.
The completed surveillance procedure, with test results, is not in the preoperational test package. Therefore, the requirement that f
the alt flow test be performed during the final stages of preoperational testing cannot be verified, Review j

Descrepancy: Flood Protection Procedures and Technical Specification Requirements Discrepancy Ducrigtlon: Tech. Spec. section 3.7.6, Flood Protection, Limiting Condition for Operation (LCO), states that flood protection shall be provided for the service water pump cubicles and components when the water level exceeds 13 feet Mean Sea Level, USGS datum, at the Unit 3 Intake structure. This LCO is applicable at all times.
The associated action statement is "With the water level at 13 feet above Mean Sea Level, USGS datum, at the Unit 3 intake structure, shut the watertight doors of both service water pump cubicles wthin 15 minutes."
The surveilla.~.ce requirements associated with the flood protection LCO are:
- 1. Measurement at least once per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when the water level is below elevation 8 feet above Sea Level, USGS datum.
- 2. Measurement at least once per 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> when the water level is equal to or above elevation 8 feet above Mean Sea Level, USGS datum.
The following listed procedures implement the flood protection requirement:
SP3665.1 Rev. 5, Flood Level Determination OPS Form 3665.1-1 Rev. 5, Flood Level Determination AOP 3569 Rev.10, Severe Weather Conditions SP 3670.2 Rev. 8, Tech Spec Related PEO Rounds (Mode 1-4)
OPS Form 3670.2-6 Rev. 7, Shift Outside PEO Tech Rounds (Mode 1-4)
SP 3672.3 Rev 4, Tech Spec Related PEO Rounds (Mode 5/6)
OPS Form 3672.3-3 Rev. 4, Shiftly Outside PEO Tech Spec Rounds (Mode 5/6)
Three flood protection requirement discrepancies were identified.
- 1. No procedural guidance exists that describes the flood protection program actions to be taken when the water level is determined to be equal to or greater that 13 feet above mean sea level, USGS datum as documented in OPS Form 3665.1-1 Rev,5. Section 7, Summary of changes, of SP3665.1 Rev. 5, Flood Level Determination , identifies one of the changes made in revision 5 of this procedure as " References to the adions taken if water level exceeds 13 seet have been removed. These actions are dealt with in EOP 3569, Severe Weather Conditions". Procedure EOP 3569, Severe Weather Conditions Printed 9/19S7 3:18:34 PM Page 1 of 3
DR No. DR,*vlP3-0161 Northeast Utilities ICAVP Milistone unit 3 Discrepancy Report does not exist. This was confirmed by referencing Unit 3 Emergency Operating Procedures Index,3500 Procedure Index, Rev.141 dated 5/20/97. Procedure AOP 3569 Rev.10, Severe Weather Conditions, does exist and may be the correct reference rather than EOP 3569. This AOP does not adequately identify the Tech Spec required actions to be taken if the water level reaches or exceeds 13 feet.
The performance requirements identified in the Tech. Specs. are not adequately translated into the referenced operating / surveillance procedures.
- 2. Page 2 of Procedure SP3665.1 Rev. 5, Flood Level Determination, states in the box identified as Basis Information, "This monitoring is required every 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> even if the watertight doors and the normal sump drains are closed. No exemption is provided in T/S 4.7.6.b which would allow cessation of monitoring'. Page 3 of the same procedure states in the box identified as CAUTION, "With sea level approaching 13 feet above mean sea level weather conditions may warrant entering T/S 3.7.6 LCO and discontinue surveillance until conditions allow". These statements are in direct confli?
Page 5, Step 5 of Procedure AOP 3569 Rev.10 required the operator to ' Monitor sea water level at the intake structure hourly until wind speed exceeds 50 mph.' This step is not consistect with OPS Form 3665.1 1 Flood Level Determination which requires that the waterlevelis recorded every two hours. if the operator ceases to monitor the sea level when the winds exceed 50 MPH the required Tech Spec surveillance that is described in SP 3665.1 Flood Level Determination and OPS Form 3665.1-1 Flood Level Determination may be missed if the water level is high during high wind conditions.
These procedures appear to be contredictory and may preclude the service water system from being monitored in accordance with the Technical Specification during high winds and/or flooding conditions.
- 3. Tech. Spec. section 3.7.6, Flood Protection, requires determination of water level referenced to "Mean Sea Level, USGS datum, at the Unit 3 intake structure. We were unable to determine from the documentation provided, what type instrument was used to determine the mean sea level,
, specifically where the instrumentation is located, or how the instrumentation is calibrated and referenced to the USGS datum.

Discrepancy: FSAR page 9.2-8 description of SWP strainer motor control switch does not match drawing information.
Description:
FSAR page 9.2-8 states: "The service water pump strainer motor is controlled from the main board by a OFF/ AUTO /RUN switch with indicating lights,"
Per the Control Switch Contact Diagram the switch escutcheon reads OFF/ AUTO /ON. In addition, per the schematics and logics there are no indicating lights.
This was confirmed by reviewing the following drawings:
