1.0 BAC'.;CROUND The pressure temperature (P T) curves in the Technical Specifications are established to the requirements of 10CFR$0, Appendix G [1] to assute that brittle fracture of the reactor vessel is prevented. Part of the analysis involved in developing th e P.T curves is to account for neutron irradiation embrittlement effects in the core region, or beltline. In the past, Re5ulatory Guide 1.99, Revision 1 (2) has been used to predict the shift in nil ductility reference temperature (RTNDT) as a function of neutron fluence in the
' beltline region. Regulatory Guide 1.99, Revision 1 (Rev 1) was developed assuming that copper (Cu) and phosphorus (P) were the key chemical elements influencing embrittlement.
Regulatory Guide 1.99, Revision 2 (3) (Rev 2) was issued in May 1988. Rev 2 represents the results of statistical evaluation of commercial reactor surveillance test data accumulated through about 1984. There are two basic factors used in the calculations to predict the shift in RTNDT shown in the regulatory guide, a chemistry factor
- and a fluence factor. Both of these factors remained the same from i
Rev 1 to Rev 2 of the regulatory guide. However, the method used to calculate each faator has been significantly changed. The chemistry factor (CF) has been changed from an equation based on Cu and P in Rev 1 to tables of CF values based on Cu and nickel (Ni), with separate tables for plates and for velds. The fluence factor has been modified
! in Rev 2 to a somewhat more complex form.
Generic Letter 88 11 [4) requests an evaluation of the impact of Rev 2 on existing P T curve s , and a schedule to implement Rev 2.
Based on that request, this report presents the Rev 2 impact i
evaluation for Limerick Unit 1 and the corresponding results. Actions required for implementation of Rev 2 are presented in the previoue section, along with recommendations concernin5 the timing of these 3 actions in light of planned plant activities and industry efforts l underway, i

. . l o . . .
2.0 IMPACT EVALUATION The beltline region in the Limerick 1 plant consists of three shell course No. 1 plates, three shell course No. 2 plates, and their associated welds. Two categories of beltline welds are identified:
"shop" welds and "field" welds. The shop welds represent vertical ,
seams which were made prior to shipment of pre assembled ring segmants to the Limerick 1 plant site. The field welds (i.e., girth welds) were made at the plant site. Since all weld metal heats are not
, traceable to specific welds, all metal heats were considered in this analysis. However, only the four most limiting veld heats of each
., category are documented. The LPCI nozzles, because of their exposure to a peak End of Life (EOL) fluence (1.6 x 10 17 n/cm 2 at the 1/4 thickness depth) in excess of 1 x 10 17 n/cm 2 (E > 1MeV), are also considered. Attachment A shows the details of the impact evaluation for Limerick Unit 1. The process followed for each beltline material is described below.
Chenistry j The chemistry data for all of the beltline region plates, the l
beltline veld filler material, and the LPCI nozzles shown in Attachment A were taken from the GE design record file material that i supports Section 5.3 of the Limerick FSAR (5).
The values of initial RTNDT shown in the attachment were taken from the GE desis;n record file material that supports Section 5.3 of the Limerick 1 FSAR (5). These values were based on 30 fr. lb impact ener6y verification testing, with longitudinal Charpy specimens used for plate, done at the time of vessel fabrication. The calculations of these initial RTNDT values in the FSAR vore based on a CE procedure which established conservative values of RT NDT from the fabrication j test data. Since the initial RTNDT values are conservative, the term in the Rev 2 margin expression og is assumed to be :ero.

Fluence The value of neutron fluence for 32 effective full power years (EFPY) shown in Attachment A is based on peak fluence predictions as noted in the FSAR. Lead factors applicable to the use of this fluence value give a peak fluence value at the vessel inside surface, fsurf-The Rev 1 ealculations of RTNDT shift are based on a calculated value of fluence /4 thickness into the vessel vall from the inside surface (1/4 T). Tae Rev 2 method is to take the calculated fluence at the vessel insida surface, fsurf, and attenuate that value to the depth x accordin5 tre the relationship:

This method results in a slightly higher fluence at the 1/4 T location.
I {
Surveillance Test Correction Factor .
Aav 1 allows for consideration of credible surveillance data when it becomes available. If the RTNDT shift seen in the surveillance i
data is larger than initial predictions, Fev 1 shift prejictions are increased by this factor. For Limetick Unit 1, where surveillance I
testing has not yet been performed, the correction factor does not apply, and 16 set to 1.0.
i
$Hi{T and Adjusted Reference Teneratugg (ART) l The RTNDT shif t calculations in Attachment A are based on the ,
procedures in Rev 1 and Rev 2. For Rev 1, the value of SHIFT is l computed with the equation: !
SHIFT - (STF)*[40 + 1000(tcu . .08) + 5000(tP - .008)]*(f)0.5 f8 where STF - surveillance test correction factor f - fluence for the given EFPY / 10 19

l For Rev 2, the value of SHIFT consists of two terms:
SHIFT - ARTNDT + Margin whers ARTNDT - (CF]*f(0.28 - 0.10 log f)
Margin - 2(ag 8 + a32 ).5, Chemistry factors (CF) are tabulated for welds and plates in Rev 2 of the regulatory guide. The margin term a3 has set values in Rev 2 of 17'T for plate and 28'T for veld. However. a3 need not be greater than 0.5*ARTNDT' The values of ART in the attachments are computed by adding the SHIFT terms to the values of initial RTNDT ART - initial RTNDT + SHIFT.
LPOI Nozzles A review of all I.PCI nozzles in the beltline region shows that a conservative estimate of Cu=.184 and the maximum Ni=.85% applies for the worst case LPCI onzle. Based on these chemistry values, the worst case LPCI nozzle has a Rev 2 ART of 38.4'T at 32 EFPY, Since this is less than the 40*F RTNDT applied to the limiting vessel discontinuity curves, the LPCI nozzle is bounded by the limiting vessel discontinuity curves. Further, the most limiting LPCI weld, 662A746 / Lot H015A27A, has already been considered in the shop welds section at the higher fluence. Based on these two points, further consideration of the LPCI nozzles in this evaluation is unnecessary.

,. 1 3.0 RESULTS AND RECO.WENDATIONS Results and Conclusions The impact of implementing Regulatory cuide 1.99, Revision 2 (Rev 2) can best be determined by comparing the Adjusted Reference l i
Temperature (ART) values based on Regulatory Guide 1.99, Revision 1 (Rev 1) and Rev 2. Table 1 shows the ART values at 4 effective full power years (EFPY) and at 32 EFPY for each beltline material in Limerick Unit 1. The following conc 1'usions are drawn from the results iS this table: '
4 L
- 1. Tha Rev 2 ART values at 32 EFPY for this unit are below 200'F, which is the allowable limit in 10CFR$0, Appendix C. Therefore,
' implementation of Rev 2 will not result in any additional analysis, testing or provisions for thermal annealing.
- 2. The ART value which applies to the pressure temperature (P T) curves in the Technical Specificatiens is 56'F at 32 EFPY. The maximum Rev 2 ART value in Table 1 is 85.6'T at 32 ETPY, i Therefore, the Rev 1 32 ETPY P T curves are less conservative than 32 ETPY curves that would be generated with Rev 2. However,
! the current P T curves are applicable up to 10 EFPY if ART is calculated according to Rev 2 methods. Therefore, the current
, curves are conservative for several more years of operation.
l
- 3. The worst case LPCI nozzle is also included in this beltline region analysis due to its predicted fluence value at 32 EFPY.
I Since it has a Rev 2 ART at 32 EFPY less than the 40'T RTypt applicable to the limiting vessel discontinuity curves, the LPCI nozzle is bounded by the limiting vessel dit ontinuity curves.
Therefere, the discontinuity limits shown on the P T curves of the Technical Specifications need not be adjusted as a result of
! implementation of Rev 2.
i i
l 5 t
i l \
i Recorrendations Generic Letter 8811 requires that Rev 2 be implemented within two outages. Based on the results on the previous page, the following recommendations are made concerning Rev 2 implementation:
The current P T curves are conservative for up to 10 EFPY of operation. However, since the implementation of Rev 2 results in !
calculated 32 ETPY ART values mors conservative than those of Rev 1 at 32 EFPY, revision to the P T curves within two outages
- r is appropriate.
I e
Philadelphia Electric has authorized the revision of the P T !
t curves according to the methods of Rev 2. When Rev 2 is i f
implemented, the P T curves will be changed to include the Rev 2 :
shift corresponding to an appropriate value of EFPY. Changes !
will be required to section 5.3 of the FSAR, as well as section 3/4.4.6 and the corresponding bases of the Technical Specification, p P
