SUBJECT:

INSTRUMENTATION AND CONTROL QUESTIONS FOR NYSE&G 1 AND 2 In our December 27, 978 letter, we informed you that your Preliminary Safety Analysis Report (PSAR), which w.s tendered as part of your application for construction permits and operating licenses for NYSE&G 1 and 2, was sufficiently complete for docketing. We stated in that letter that we had encountered difficulties with the information provided in your PSAR in the area of instrumentation and control. We indicated that we were ccc!inuing to develop our need for information in this area and would forward.nstru-mentation and control questions in the near future.

Accordingly, our acceptance review questions in the area of instrumentation and control are enclosed. These questions were developed using your PSAR, supplemented by your letter of December 19, 1978, in which you forwarded a draft of a future amendment to Chapter 7 of your PSAR.

This draft amendment provided additional guidance regarding the integration of the NYSE&G PSAR with CESSAR, SWESSAR, and solid state protection system as described in the TVA Yellow Creek application.

Please provide a date by which we can expect to receive responses to the enclosed questions. We will utilize this date as a factor in the prepara-tion of our Safety Review Schedule for the NYSE&G application.

Please contact us if you desire any discussion or clarification of the Enclosure.

Sincerely, b

032.0 INSTRUMENTATION AND CONTROL SYSTEMS BRANCH 032.1 Discuss the following aspects of environmental qualification as it

( 3.11 )

relates to Chapter 7 of the NYSE&G PSAR:

(1) The staff's Safety Evaluation Report of SWESSAR-P1 (NUREG-0096) states in Section 7.6.1, " Environmental Qualification of Class lE Electrical Equipment":

"The details for the development of the program, including the acceptance criteria, have been defined as an interface matter to be addressed in the application for a construc-tion permit by a utility applicant referencing the SWESSAR-Pl design."

Therefore, provide the details of the qualification program, as discussed above, including the acceptance criteria or provide a schedule for submittal.

The schedule should include the submittal date for the details of the program, the acceptance criteria, and the projected submittal date for the test results.

(2) NYSE&G utilizes portions of the Yellow Creek design that are within the CE scope e :upply but not covered by the CESSAR or SWESSAR PDAs.

For these electrical, instrumentation and control components used in the NYSE&G design, provide the same environmental qualification program details as requested in (1) above.

032.2 Sin _e the NYSE&G PSAR references the Yellow Creek solid state (7.1) protection system design as well as CESSAR and SWESSAR, provide the following information:

(1) A list of the systems or portions of the systems used in the NYSE&G design which will be designed identically to the cor-responding systems on Yellow Creek, CESSAR, or SWESSAR as applicable.

(2)

For any system or portions of the systems which are not identical, provide a complete description which meets

'e requirements of the R.G.1.70 (Standard Format and Cont.it of Safety Analysis Reports for Nuclear Power Plants).

For these systems, also address the " Acceptance Criteria for Controls" of Table 7-1 of the Standard Review Plan.

(3)

Explain the terminology " functionally identical" used in Section 7.1 of the NYSE&G PSAR with details for each system discussed.

03?

For the Plant Protection System, provide the following inforr.ation:

(7.2 i (1) Veri f) that the circuitries of the NYSE&G Compartmented Plant Protection System (CPPS) are identical to the circuitries of the Yellow Creek protection system and that the NYSE&G design is simply a repackaging of the Yellow Creek circuitries in separate cabinets.

(2) Verify the circuitiies of the Reactor Trip Switchgear for NYSE&G are identical to the circuitries of the Yellow Creek design and that they have been repackaged (i.e. separate cabinets) for NYSE&G.

If any differences in design are identified, verify that these differences comply with all applicable safety criteria.

032.4 For the fiber optic inter-cabinet interfaces of the Compartmented (7.2)

Plant Protection System (CPPS), provide the following information:

(1) Provide a complete description of the design in conformance with R.G. 1.70.

(2) Provide the specific design bases and design criteria and address the " Acceptance Criteriu for Controls" of Table 7-1 of the Standard Review Plan.

(3) Specify whether this area is in the scope of design of CE or S&W or others.

(4)

For this area of design, identify any changes to the interface requirements evaluated by the staff during the PDA reviews of CESSAR and/or SWESSAR or the review of CENPD-172.

032.5 In Section 7.3 " Engineered Safety Features Systems", the " Solid (7.3)

State Component Control System (SSCCS)" is discussed.

It is our understanding that the SSCCS is Yellow Creek terminology and thrit this system is referred to as the "Corpartmented Plant Protection System (CPDS)" in other sections of the NYSE&G application.

(1)

Please verify this assumption.

If not true, provide a complete description of this sys tem in conformance with R. G.1.70.

Include specific design bases and design criteria and address the " Acceptance Criteria for Controls" of Table 7-1 of the Standard Review Plan.

(2)

Specify whether this area is in the scope of design of CE or S&W or others.

(3)

For this area o f design, identify any changes to the interface requirements evaluated by the staff during the PDA reviews of CESSAR and/or 5WESSAR.

09 03B

' 032.6 Clarify whether the " Plant Monitoring System (PMS)" is in the CE (7.7) or S&W scope of supply for NYSE&G.

For this area of the design, identify any changes to the interface requirements evaluated by the staff during the PDA reviews of CESSAR and/or SWESSAR.

032.7 Your letter of December 19, 1978 forwarded a draft of a future (7.8) amendment to C.hapter 7 of the NYSE&G PSAR.

Section 7.8 of the draft amendment uses the terminology " functionally identical."

Explain this terminology with suitable examples. Also identify any changes to the SWESSAR/CESSAR interface requirements caused by reference to portions of the Yellow Creek design or by other changes to the I&C design which are unique to NYSE&G.
