  • Evaluation of Flaws in Ferritic Piping", Dated October 1988 we note the following:

Background and Discussion: 1)The applied loading for the pressure stress, weight stress, etc., as identified on page 7 of the calculation and used in the calculation, were not referenced properiy, The basis for the i values used appear to be assumed bounding values.

2) Based on a review of the EPRI Report (ii) the formula for limit stress of the axial through wall crack on page 11 of 45 is incorrect. The numerator of the formula should read (1 x) instead of (1+x). The limit stress formula for a 'part through wall" axial crack can not be applied for a through wall axial crack since the limit stress approaches 0 as alt approaches 1. The limit stress for through wall axial stress per the EPRI Report is approximately 1/3 of the calculated value on page 11. This will change the failure mode of the axial flaw from brittle to ductile tearing failure mode.
3) Based on a review of the input parameters for the PCFAD analysis (pages 13-43),used to evaluate circumferential cracks, it is not clear that a pressure load was included in the PCFAD analyses.

4)As identified in the PCFAD input listing on page 13, the sourcas of Ramberg Osgood (alpha) material constant (taken from the EPRI report) and the value of "n" (taken as the PCFAD default value) are not taken from the same document. Since these constants are related to the referenced yield strain and stress, they should be from the same source. Other material data such as JR curve for FAD curves was not documented. Discrepancy: Printed 11497 3 AQ.1o PM Pege 1 of 2'

Northeast Utilities ICAVP DR No. DR MP3 0382 Millstone Unit 3 Discrepancy Report Based on a review of reference (ii), we believe the failure mode of a postulated axial crack will be ductile tearing vs. brittle failure. Therefore, certain axial crack / pipe size combinations may result in stable conditions. Based on a review of the PCFAD input / output listing for the evaluation of circumferential cracks, the values of ' alpha" and 'n' used are not taken from a common reference source and the a pressure load is negleded. Therefore, the predicted stable circumferential crack sizes and safety factors may be unconservative.

Per FSAR TaNe 6.5-1, the Charging Pump, Component Cooling Pump, and Heat Exchanger Exhuast System is in compliance with RG 1.52 Rev. 2, position C.1.c. Per FSAR TaNe 6.5-1, the Supplementary Leak Collection and Release Systtsm is in compliance with RG 1.52, Rev. 2, position C.1.c. Per RG 1.52 Position C.1.c, The design of each adsorber section t should be based or, the concentration and relative abundance of the lodine spec!es (elemental, particu: ate, and organic) which should be consistent with the assumptions found in RG 1.3,1.4, and 1.25.

Exception is taken to the requiremerit of any cooling mecnanism satisfying single-failure criteria because a backup mechanism is provided, in addition, exception is taken to provide humidity control for the decay heat removal system cooling air flow which uses room air of less than 70% relative humidity. Per FSAR Table 6.5-1, the Charging Pump, Componer,t Cooling Pump, and Heat Exchanger Exhaust System is in partial compliance with RG 1.52, Rev. 2, position C.3.k. Adsorbers provided with sprinkler system. See Section 1.8. Per FSAR Table 6.51, the Supplementary Leak Collection and Release System is in partial compliance with RG 1.52, Rev. 2, position C.3.k. Adsorbers provided with sprinkler system. See Section 1.8. Per RG 1.52 Position C.3.k The design of the edsorber section should consider possible iodine desorption and adsorbent autoignition that may result from radioactivity-induced heat in the adsorbent and concomitant temperature rise. Acceptable designs include a low-flow air bleed system, cooling coils, water sprays for the adsorber section or other cooling mechanisms. Any cooling mec';anism should satisfy the single-failure criterion. Per FSAR Table 3.21, the ESF filter trains satisfies the requirements of ANSI N509 in effect at the time of equipment order.

(NOTE: Consideration must be given to heat of adsorption in determining maximum adsorbent temperature). For this purpose a minimum circulatory air flow shall be available for all operational modes of the Unit and shall be based on the maximum possible radioactivity loading on the adsorbent beds. Water spray or deluge systems i are not acceptable for this purpose. The use of sprays is acceptable for fire protection (i.e., casualty loss) purposes, The design air flow for filter units 3HVR*FLT1 A/1b is 30,000 cfm per P&lD EM-148A 24 and the design air flow for filter units 3HVR*FLT3NB is 9,500 cfm. At these air flows the filter units are not considered small capacity ESF atmosphere cleanup systems. The exception to RG 1.52, Rev. 2, position C.3.k implies that there is a calculation that shows that the decay heat from collected radiolodines on the adsorber would not result in the bed temperature exceeding 250*F. UIR 2172 states that this calculation has not been fNnd. The disposition of UIR states that a calculation is to be prepared for the control room filter units but does not address the SLCRS and ABVS filter units. The use of a sprinkler system for adsorbent cooling per FSAR Table 6.5-1 does not meet the requirements of ANSI N509-1976 section 4.9 which states that water spray or deluge systems are not acceptable for this purpose.

Two of the three exceptions refer to time to criticality after an unmitigated boron dilution accident (Page 15.4-23 and Table 15.4-1). These comments - were not incorporated because the recommended changes did not represent the results of the analysis of record performed for Cycle 4. Subsequently, Westinghouse issued NEU-97-204 (attached) to officially confirm this omission. The third exception is associated with additional delays added into the analysis to account for Shutdown Margin Monitor response times (Page 15.4-19).

There is one exception to the Westinghouse comments. A comment on Page 15.4-23 refers to time to criticality after an unmitigated boron dilution accident. i This comment was not incorporated because it did not represent the results of the analysis of record perfc;med forCycle 4. Subsequently, Westinghouse issued NEU-97-204 (attached to - M3-lRF-00270) to officially confirm this omission. There were two other comments implemented based on a re-evaluation prompted by this DR:

1. On Page 15.4-15, Westinghouse changed the DNBR limit from "1.30" to "the safety analysis limit value." This change was overlooked initially by NU in FSAR CR 97-MP3-54 but has since been added to the FSAR CR.

2. On Table 15.4-2, Westinghouse changed the value of the l

DNBR limit. Their changed number represented cycle specific l data. The table's title implies that the content is ' typical'so tiie change was not initially incorporated. Upon further review, Safety Analysis has decided that the table should reflect cycle specific data rather than generic data. This change has been added to the FSAR CR. Refer to the copy of FSAR CR 97 MP3-54 attached to M3 IRF 00270 (ICAVP response to DR-MP3-0023) for ch9nges i associated with FSAR section 15.4. The FSAR CR is currently awaiting PORC approval.

The filter test is written to satisfy Tech Spec 4.9.12 requirements. It is specifically referenced in the Tech Spec that testing methodology, which includes vendor qualification and surveillance acceptance criteria, be in accordance with ANSI N5101980. Specifying compliance with Regulatory Guide 1.52 and ANSI N5101980 is an enhancement to the survelllance pmcedure and OFS form but not required. Also, the procedure and surveillance forms are written in accordance with the ANSI standard and the Reg guide. Vendor qualification can be assured in two ways. First, the ~ Purchase Order that is used to procure the vendor specifies personnel to be qualified to ANSI N510-1980 (pages 3 aad 5 of attached PO).

The discrecancy was identified and i documented in OIR 230, Disposition of the discrepancy was to review the alarm setpoint, determine the requirements and make appropriate changes. The OIR disposition determined that the FSAR staould be changed to eliminate any numerical value associated with the deviation alarm. FSARCR 97 MP3-54 was initiated 3/3/97 and includes the necessary change to section 15.4.6.1. A related CR, M3-07-0950, was initiated on 3/23/97 to document a discrepancy between the Annunciator Response Procedures (ARP) and the assoclated l&C loop calibration setpoint. The setpoints for the deviation alarm is determined by the Westinghouse Precautions, Limitations and Setpoints (PLS) document (Page 66 attached). The PLS lists the setpoints as 1.2 gpm for boric acid to the blender and 8 gpm for total makeup flow.

NU's response does not resolve the discrepancy noted for paragraph 1.2.8.b of DC 2 as it relates to references listed in the procedure which cannot be found. We believe Procedure DC 2 should be revised to state that revisions to a procedure with missing references may only be approved when the missing information has no effect on the contents of the revision, in addition, the extent of the condition for past procedures developed following DC 2, paragraph 1.2.8.b should be addressed. - Printed 11G97 3 27;17 PM Pope 2 of 2 l l --}}
