Beaver Valley Power Station, Unit No.1 Reactor Vessel PTS Assessment Second RAI Response NRC Ouestion 1:
It is the NRC staff's position that DLC should use 34 F for the margin term when evaluating lower shell plate B-6903-1 rather than the value of 29.1 F used in WCAP-14543. The use of 34 F for this margin term is consistent with the value previously accepted by the staffin DLC's previous PTS evaluation.
Response to NRC Ouestion 1:
The Duquesne Light Company requests a meeting with the management and staff of the l NRC to discuss the use of the 34 F margin term and compliance with 10 CFR 50.61.
This has been preliminarily discussed with the " : aver Valley NRC Sr. Project Manager.
Information regarding NRC Question 1 will be provided following the requested meeting.
NRC Ouestion 2:
Recently, information provided from a French source has indicated that core barrel l
support rings may be shadowing surveillance capsules and the dosimeters within them, in some RPV surveillance programs. The NRC staff has begun to discuss this issue with Westinghouse. Westinghouse staff members are aware of the NRC staff's concerns that, if these supports are not modeled correctly, this may lead to deviations between measured and calculated neutron fluence values. Assess whether such a problem may exist for the measured and calculated fluence values in the case of BVPS-1 and provide drawings of the reactor vessel internals which show the relative location of the baffle radial support plates (baffle fonners), the surveillance specimen capsules, and the dosimeters and Charpy impact specimens within the surveillance capsules.
Response to NRC Ouestion 2:
The design of the Beaver Valley Unit 1 Reactor Vessel internals includes eight former plates spanning the radial distance between the external boundary of the baffle plates and the inner radius of the core barrel. Due to the shape of the perimeter of the reactor core, the radial extent of the former plates varies significantly with azimuthal angle.
Therefore, an accurate evaluation of the effect of the presence of these former plates on the neutron environment at surveillance capsule and reactor vessel locations would require three-dimensional transport analysis.
l l .
Attachment Reactor Vessel PTS Assessment Second RAI Response Page 2 .
l c l The configuration of the former plates at Beaver Valley Unit 1 is depicted schematically l- in Figure 1 (attached). Also shown in Figure 1 are the relative locations of materials test ;
l specimens and dosimetry sensors within a surveillance capsule with respect to the former i plates. From Figure 1, it can be seen that the surveillance capsules are impacted l primarily by only fonner plates C and D. An expanded representation of the materials ,
l test specimens and dosimetry sensors relative to these two former plates is provided in ;
l Figure 2 (attached). The specific axial dimensions for the former plate elevations, the i
! material test locations, and the dosimetry sensor elevations are listed in Tables 1 through l l 3, respectively. Relative to Figures 1 and 2, as well as Tables 1 through 3, it should be i noted that all dimensions are referenced to the axial midplane of the active core.
From Figure 2, it can be seen that portions of Charpy compartments 4 and 5 lie in line ,
l with former plate C; and portions of tensile compartment 1 and WOL compartment I lie in line with former plate D. None of the other materials test specimen compartments fall in direct line with the former plates. In the case of the dosimetry sensor sets, only the bottom tips of the copper and nickel wires contained in Charpy compartment 5 lie directly in line with the former plate. The remaining dosimetry sensors, particularly l those at the top, middle, and bottom of the surveillance capsule are positioned such that
! they are minimally influenced by the presence of the former plates.
l
! To date three surveillance capsules (V,U, and W) have been withdrawn from Beaver Valley Unit 1. In Table 4, a summary of the measured specific activity of iron ,
manganese (Fe-54 (n,p) Mn-54) sensors irradiated at five axial elevations within :
capsules V,U, and W is provided. In Table 4, measurements are provided on an absolute l basis as well as relative to the average specific activity for each capsule. It should be l noted that the average activity is the quantity used in the surveillance capsule dosimetry l evaluations. From Table 4, the standard deviations associated with the average data sets i
range from 3.5% to 4.7%, a range consistent with the 5% uncertainty assigned to the Fe-54 (n,p) Mn-54 reaction rates used in the capsule dosimetry evaluations. It is evident from the data provided in Table 4 that no significant effects due to the presence of former plates C and D are observable, and therefore, are bounded by the current margin term in the determination of RTvrs.

l NRC Ouestion 3:
The NRC Staff has established the position of not accepting adjustments to calculated l neutron fluence values based on the use of dosimetry data and the FERRET code (for l reference, see the staff's safety evaluation on the PTS reassessment for Palisades, j December 20,1996). Perform DLC's PTS reassessment based on calculated fluence !
l values for determining:
]
(1) surveillance capsule fluences, I (2) the chemistry factor from BVPS-1 surveillance results, and (3) the EOL fluences of the RPV plates and welds.
Recognize that the NRC staff expects that this reevaluation will include any changes which result from DLC's investigation into the need to address the core bafUe radial support plates raised in #2 above. If remodeling and recalculation is necessary, the staff requests that DLC submit a schedule for resolution of this issue within 30 days of receipt of this letter.
Response to NRC Ouestion 3:
The PTS evaluation provided in the August 6,1996, Beaver Valley Unit I submittal was performed using best-estimate fluence values for both capsule and vessel evaluations.
However, to provide a point of comparison, a re-evaluation of the RTat based on the use of calculated fluence and measured charpy shift has been performed for the limiting lower shell r&x material, which is bounding for the other materials and welds within the Reactor Ve.:.r.l.
From the fluence evaluations provided in WCAP-14554, " Beaver Valley Unit No.1 Fluence Re-Evaluation," S. L. Anderson, June 1996, the following calculated and best-estimate fluence values were reported for the three surveillance capsules withdrawn from the reactor to date.

Attachment
{teactor Vessel PTS Assessment Second RAI Response Page 9 l The best-estimate fluence values and the measured RToat shift data from the capsule l evaluation resulted in a plant specific chemistry factor for the lower shell plate material of 163.4. This value was provided in the August 1996 submittal.
A re-evaluation of the chemistry factor using the calculated capsule fluence along with the measured shift data results in a reduced chemistry factor value (CF = 159.9).
Based on the use of a chemistry factor of CF = 159.9, an initial RToat of 27 F and using a conservative margin of 34"F, results in the PTS screening criterion of 270 F being 2
reached at a fluence of 3.22E+19 n/cm . Based on the calculated maximum vessel
! fluence for the Beaver Valley Unit I lower shell plate at EOL (27.1 EFPY) of ,
2 '
~2.92E+19 n/cm , it can be seen that the screening criteria value of RToat will not be reached within the 27.1 EFPY operating lifetime of the unit.
Therefore, the use of calculated fluence values versus the best-estimate values contained ,
in our August 6,1996, submittal does not impact the conclusions reached in the current Unit 1 PTS assessment. Based on the above, the need for PTS reassessment is not
- considered necessary.
l Additionally, as was noted in the response to Question #2, the effects of the shadowing ;
by the former plates is very small and within the standard calculational error expected for reaction rates associated with dosimetry and fluence evaluations. Therefore, no l adjustments need to be added to the above calculated fluence values.
