Page 2 of Table 3.2-1.shows the service water pump cubicles 1.60 of the circulating and service water pumphouse as QA Category I.
Expand this item to identify the associated 2.2 structures, systems, and components under the control of the QA p'rogram.
- c. of Northeast Utilities letter (Counsil to 2.3 Youngblood) of March 22, 1984, addresses QA for certain TMI 2.4 items identified in Enclosure 2 of NUREG-0737. This letter 2.5 are included notes that " specific safety-related TMI items within their respective systems in FSAR Table 3.2-1."
2.6 Provide a commitment that the items not listed in 2.7 FSAR Table 3.2-1 but identified in (enclosure 5.C) of your March 22, 1984 letter will be 2.9 subject to the pertinent requirements of the FSAR operational QA program or justify not doing so.
2.10 d.
The Millstone 3 FSAR Section 9.5 and its reference to the 2.11
" Fire Protection Evaluation Review" address QA for fire 2.12 protection, but the commitments therein appear to address QA Q260.58-2
u12179fsr2748 04/03/85 241 MMPS-3 FSAR s-during design and construction only. Revise the description 2.13 of the QA program for fire protection to address the operations phase.
o e.
Table 3.2-1 does not adequately identify specific ESF 2.14-equipment used for the mitigation of radiological consequences in.the event of a DBA. A specific example of 2.16 this lack of definition can.be found at the middle of page 16 of Table 3.2-1 which lists " Instrumentation and 2.17 controls-required to perform safety functions for QA Category I ventilation systems," without identifying these 2.18 parts. This same approach holds true for Habitability 2.19 Systems and Fuel Handling Systems.
Clearly identify in 2.20 Table 3.2-1 the items that are used for the mitigation of DBAs.
f.
In its letter to the NRC of March 22, 1984 (B11027), the 2.21 applicant states that the Millstone 3 Health Physics Program 2.22 will be subject to "an extensive internal audit program."
Provide assurance that the auditors are independent of NU's 2.23 Health Physics organization.
Response
2.26-Structures,.
systems, and components which have been designed, 2.27 procured, and constructed with QA control are identified in FSAR 2.29 Section 3, Table 3.2-1 (QA Category I Structures
- Systems, and Components). Table 3.2-1 will-serve as input to the Category I 2.30
- material, equipment, and part list (MEPL) for Millstone 3.
The MEPL 2.31 will be generated and controlled in accordance with the operational Quality Assurance Program as described in FSAR Section 17.2 2.32 Items. added to Table 3.2-1 will be included in the MEPL when that 2.33 document is generated.
a-1 Bioltigical Shielding 2.36 Biological shielding in the safety-related structures 2.38 are of reinforced concrete walls or panels and as such form part of the structure. Since the structures are 2.42 safety-related and subject to corporate QA program requirements, the biological shielding will not be 2.43 listed as a separate item in FSAR Table 3.2-1.
2.44 a-2 Fabricated Supports such as Unistrut or Superstrut 2.47 The fabricated supports such as unistrut or superstrut 2.49 used to support Seismic Category I systems and components are part of the system or component. Since 2.52 the operational QA program covers. these systems and components, these fabricated supports will not be listed as a separate item in FSAR Table 3.2-1.

Health Physics Program 7.9 As discussed in FSAR Chapter 12, the Millstone 3 health 7.11 physics program, including the necessary facilities and equipment, will be of high quality and meet the 7.12 applicable Regulatory Guides and NUREGs.
The program 7.13 will be subject to its own quality controls, including an extensive internal audit program. These audits are 7.14 conducted in accordance with NUSCo's Corporate Management Program for maintaining occupational exposure las low as reasonably achievable (ALARA). The 7.16 health physics program is implemented by the personnel from the operating plant organization whereas the audit of the health physics program is perfonmed - by the 7.17 personnel from NUSCo corporate headquarters in Berlin.
- However, the health-physics program is not 7.18 safety-related and hence, none of the items above should be included in FSAR Table 3.2-1 or be subject to 7.19 the requirements of the operational QA program.
