R EOUEST -FOR ADDITION A' INFORMATION INDIAN'PCINT* UNIT'3 1.
' Describe.the features.that are provided in the fellowing
. systems to satisfy the requirements of Regu'atcry Guide 1.47:
a) Containment Ventilation Isciation, b) Containment Spray,(CS),
c) Containment Iselation (CI), and d) Safety Injection (SI).
- 2. With regard to note 12 on Drawing 9321-LL-303i3 Sheet 2A, describe the method and. devices that are used to control the pcsition of the purge supply fan louver.
- 3. Identify all-syste=s, other than liquid systems penetrating containment, that receive containment isolation Phase A cr Phase B signals.
4.
What is the time setting of the SI timer?
5.
What function does the ASI relay play in the CS circuit?
(Ref.: Drawing 113E503, Sheet 6) 6.
De the CS, CI and SI valves all have tuc-position, maintained contact, manual position control switches?
7.
Describe and provide photographs of the locatien of the reset and bypass switches that are a part of any engineered safety feature circuit.
3.
Indian Point 3 must meet.the ~ conditions of General Design Criteria 1,
2, 4 and 23 of Appendix A and Sections III and XI of Appendix 3 (tc 10 CFR Part 50) and the national standards identified in Part II
" Acceptance Criteria," of Standard Review Plan Section 3.11 (which includes IEEE Std 323). To ensure that these conditions are met; (1) Provide the information requested in Parts 2 thru 6 be)ou for the following equipment:
(a) MG-6-latching relay; (b) " RESET" switches used.in the. logic' circuits fer;
.Centainment.. Ventilation Irelation, Containment Isolation,nContainment Spray, and Safety.
' Injection; (c)Jihe inverters that: supply power to the Safeguards
' Cabinets;
( d )- The= Safety Injection.eset ti=er;.and' (e)'The slave rel'ays.

(2') Fcr each ite= listed in Part i abcVe, provide the. design specification requirements. including:
(a) The system safety requirements.
(b) An environmental envelope as a function of' time that' includes all extreme parameters, beth maximu,m and minimum values, expected to occur during plant shutdown, normal operation, abnormal operation, and any design basis event (including LOCA and MSLS), and post event conditions. The envelope-shall. include an explicit statement of the range of energy supply and electrical 11oads.
(c) Time required to fulfill its s.afety function when subjected to any of the extrenes cf the environmental envelepe specified in 2(b) above.
(3) Frovide the qualification test plan, test setup, tese precedures, and acceptance criteria fcr each of the items listed in (i) above.
If any methed other than type testino was used
'f o r qualification (operating experience, analysis, combined qualification, er engoing qualification), describe that method in sufficient detail ~to permit an evaluatien ci its adequacy.
(4) For each piece of equipment identified in (1): above, state the actual qualification envelope simulated during testing (defining the' duration of the hostile environment i
and the margin in excess'ef the_ des gn-requirements). If any method other than type testing was used fer qualification, identify the methed and-define the equivalent "qualificati~en envelope" so
. derived.
(5) Summarize the test results that demonstrate the adequacy of-the qualification-programs described.above.
(6) Identify the qualificat-lon-documents which centainEdetailed suppertinc informatien, including-test data,-fer items (5), -(4) and.
