- Area Code 517 788-0550 February 24, 1978 Director of Nuclear Reactor Regulation Att:
Mr Albert Schwencer, Chief Operating Reactors Branch No 1 US Nuclear Regulatory Commission Washington, DC 20555 DOCKET 50-255 - LICENSE DPR PALISADES PLAUT - RESPONSE TO LETTER DATED DECEMBER 23, 1977:
ENVIRONMENTAL QUALIFICATION I
- ~... ::~:**:;,';~/~
- ~*-** _, L
-:..*~ J;v J By letter dated December 23, 1977, Consumers Power Company was requested to address the Environmental Qualification of Safety-Related Equipment for the Palisades Plant.
Discussions and meetings with the staff helped clarify the type of information necessary to adequately respond to this letter.
The purpose of this letter is to provide our response by identifying the Design Basis Events considered at Palisades Plant, by providing the environmental qualification criteria, by specifying the documentation available for electrical equipment necessary to operate under these Design Basis Events, and by conclud-ing upon the acceptability of this documentation.
The time frame allotted for this response has been established at 60 days.
This has not provided adequate time to fully research and analyze data to ensure that all available environ-mental qualification documentation has been utilized.
While the submittal rep-resents the most accurate information compiled to date, the time frame has not allowed completion of a formal review of the submitted findings.
If, on the basis of further review, the derived conclusions are other than those specified, the staff will be notified immediately.
The Design Basis Events identified as being environmentally limiting for Palisades are the Loss of Coolant Accident (inside of containment) and the Main Steam Line Break (outside of containment).
The various environments caused by the postulated occurrences are described in Attachment 1, and are derived from pre-viously docketed submittals.
The equipment that must operate to ensure safe shutdovm of the plant during these Design Basis E-rents, and the environmental criteria and qualification of this equipment is identified in Attachment 2.
It is important to note, however, that only the equipment that is subject to a potentially hostile environment is addressed.
Further, as discussed in the pre-vious paragraph, Attachment 2 is limited. First, the list of systems a~d equip-ment has not yet received a completed formal review and, therefore, is subject to change.
Second, the qualification documentation that is listed represents the data compiled to date, and does not necessarily represent the ffiost conclusive information on record.
1780610002 r
Specifically, the Method of Qualification column of Attaclunent 2 represents only that qualification documentation that affords complete retrievability.
- Further, because of the limited time frame, little detailed environmental qualification data was obtained through contacting various vendors or in researching other dockets for equipment test results.
Performing these tasks would, undoubtedly, enhance the status of the qualification data submitted.
For that equipment that marginally meets the acceptance criteria, the Method of Qualification column of Attaclunent 2 provides justification and/or a course of action to be taken to raise the level of qualification.
In analyzing the qualification data derived for each system, it becomes obvious that the spectrum of data covers the period from plant inception to the present time.
Inherently, this means that the criteria met no one single guideline but met the specification in effect at the time qualification was accomplished.
Based on our assessment of the bounding environmental conditions and the quali-fication data presented in Attachment 2, Consumers Power Company concludes that there is reasonable assurance that Palisades will continue to operate without endangering the health and safety of the public.

ATTACHMENT 1 Envirorunental Design Conditions When considering the Design Bases Events of LOCA and high energy pipe breaks, the following adverse environments are postulated:
Environment 1 - Containment Temperature:
Pressure:
Humidity:
Chemical:
Radiation:
- Figure 1
- Figure 2 100%
- Chemical spray of boric acid (1584 to 2406 ppm of Boron) and sodium hydroxide in water solution of pH between 7 and 8.3.
- 2 x 107 Rads
- From "Contairunent Pressure Analysis," Section 14.18 of FSAR.
The temperature transient is based on a large primary coolant system pipe break.
It is recog-nized that in the event of a main steam line break the vapor temperature in containment may rise significantly above that shown on Figure 1 (even though the pressure rise has been shown to be nearly the same as for the worst primary pipe break) due to superheating of the contairunent atmosphere.
Analysis for similar containments (see Appendix 6B of Midland FSAR) has shown that the period of super-heat is short, ie, less than 100 seconds.
Further, it has been shown that inde-pendent of break type "the case which provides the highest containment pressure and hence highest saturation temperature, provides the design basis for contain-ment temperature qualification." This specifies that superheating of the con-tainment atmosphere for a short period of time does not result in superheating of the electrical components.
Since the main steam line break and the limiting LOCA result in roughly the same peak contairunent pressures, it follows that the electrical equipment temperature transient for the main steam line break will be no more severe than that shown on Figure 1.
- Assuming that injection of sodium hydroxide is manually stopped following injec-tion of 100 cf of 23 w/o NaOH, pH will be between 7 and 8.
If 200 cf instead of 100 cf is accidently injected, pH will not exceed 8.3 (letter S G Sawochka of Nuclear Water & Waste Technology to RB DeWitt dated December 14, 1977).
- MHA dose plus 40-year integrated dose (Section 6.1.3.2(d) of FSAR).
Environment 2 - Main Steam Penetration Room (MSPR)
Temperature:
Pressure:
Humidity:
Chemical:
Radiation:
- 300°F
- 0.6 Psig 100%
None Normal (Outside Containment)
- Special Report No 6, "Analysis of Postulated High Energy Line Breaks Outside of Containment," Revision 2, July 27, 1973.

Environment 3 - Main Feed-Water Penetration Room (MFPR)
Temperature:
Pressure:
Humidity:
Chemical:
Radiation:
- Special Report No 6.
- 300°F
- 0.6 Psig 100%
None Normal (Outside Containment)
Environment 4 - Fan Room (FR)
Temperature:
Pressure:
Humidity:
Chemical:
Radiation:
- Special Report No 6
- 300°F

Environment 5 - Auxiliary Building (Except for MSPR, MFPR, and FR)
Temperature:
Pressure:
Humidity:
Chemical:
Radiation:
- Normal
< 0.5 Psig 100%
None Normal (Outside Containment)
- Special Report No 6 states that for a 36" main steam line break in the turbine building, "pressure will not exceed 0.9 psig locally and will be limited to 0.5
- ps_ig at which point portions of the siding fails and relieves the pressure."
The special report further states that, "There are no essential structures for systems in the vicinity of any of these break locations and, as stated above, the building will relieve at 0.5 psid and no long duration adverse environmental conditions will occur.
The motor-driven auxiliary feed-water pump, which is lo-cated in a pit in the turbine building, is isolated from the environmental con-ditions by a gasket sealed, checker plate ceiling." The control room, diesel generator room, safeguards room and switchgear room are connected to the turbine building via access doors and, therefore, will experience high humidity.
- However, due to the reasons stated above, these rooms will not experience any significant rise in temperature.
These design environments are used to evaluate actual eQuipment environmental qualifications as described in Attachment 2.

FOOTNOTES
- 1.
The safety-related equipment at Palisades that could be exposed to Environ~
ment #1 but does not have chemical environment qualification data available is listed on Table 1.
The chemical portion of Environment #1 has been de-fined as the containment spray water containing boric acid (1580 mg/l to 2410 mg/l) and sodium hydroxide in solution at a pH between 7 to 8.3.
An effort was made to determine the exterior surface material of this equip-ment.
A search was made in Perry's Chemical Engineer's Handbook and Kirk-Othmer's Encyclopedia of Chemical Technology for an indication of the relative corrosion or chemical resistance of the materials in slightly alkaline solutions and dilute boric acid.
The solenoid valves have exterior surfaces of brass and painted carbon steel.
Brass and carbon steel were found to have ratings of fair to good for re-sistance to slight alkaline and dilute boric acid solutions.
The terms "fair" and "good" were not defined in terms of specific corrosion rates (such as mils/yr) but were presented in the references as guides for selecting materials for processing equipment where long-term exposures are involved.
The solenoid valves on the attached sheet are part of the service water con-trol for the containment air coolers.
A containment high-pressure signal that initiates the sprays would at the same time generate an SI signal which requires action by the solenoids on the service water discharge from the coolers.
These solenoids would, therefore, have no requirement to withstand the chemical environment in order to function in response to an SIS.
Corro-sion failure of the solenoid valves could occur during the long post-LOCA period.
The casing material on the containment air cooler fan motors was not mentioned in the available file references. It is assumed to be painted steel, but the type of material is unimportant since the motors will not be exposed to the full chemical environment.
The FSAR describes the fan motors as being directly connected to the fan wheel; the fans are vaneaxial type.
Paragraph 6.4.2.3 of the FSAR states that the aluminum fan blades will be unaffected by the containment spray solution due to dilution with condensate and re-moval in the pathway through the filters and cooling coils.
The dr~ve motor casings, then, would likewise not be exposed to the chemical sprays J.
1 It appears that qualification for temperature, pressure humidity and r~diation parameters would be adequate for continued operation.
The pressure transmitters listed were described as having aluminum top covers.
Corrosion of aluminum in a caustic and boric acid spray environment will occur and has been addressed in the FSAR under hydrogen generation in post-LOCA conditions.
The location of these pressure transmitters provides them with shielding from the sprays by the 607 1 El floor slab.
For similarly located 1
I t-f aluminum the FSAR assumed no corrosion for hydrogen generation.
Some of these transmitters will become submerged at which time failure by seal leakage and internal shorting would be competitive with corrosion.
PT-102A through PT-102D will have served their function prior to submergence.
PT-0751A -
D and PT-0752 A -
D are required only for steam line and feed-line break events.
The effects of submergence on these pressure transformers is discussed in our March 23, 1977 submittal.
For the cables listed on the attached sheet the known exterior (jacket) materials are polyvinylchloride (PVC) and chlorosulfonated polyethylene (Hypalon)'.
The jacket material for cable ZCX is unknown; the material is not mentioned in the Palisades cable description list or any known purchase specification.
For PVC an*d Hypalon the references mentioned earlier describe both materials as being resistant to dilute alkali and mineral acid solutions.
It is inferred from this that these materials would not undergo chemical attack by the sodium hydroxide and boric acid in the spray water.
The cable ZCX, for which the jacket material is unknown, is the coaxial cable for the power range safety channels N005 through N008.
It is not possible to offer an opinion on the chemical resistance of this cable.
However, again, the protection functions will have been completed prior to initiation of containment sprays.
As mentioned earlier, the chemical resistances were obtained from standard references.
Unless a material was listed as being "resistant" or having "excellent resistance" to chemical attack by dilute boric acid or slightly alkaline solutions, it was assumed that failure due to corrosion would occur.
- 2.
The cable testing was conducted at at least 49 psia which is less than the required 67 psia.
However, both temperature and relative humidity met design conditions.
Since the pertinent qualification criteria are temperature and humidity for cables, it is concluded that the qualification data is accept-able.
- 3.
The radiation qualification data cited in these sections is the result of vendor contact or purchase specification requirements.
In no case is it evident that the equipment was actually tested to failure.
Thus, it is felt that in all these cases the radiation levels cited are the minimum levels with unspecified margin to failure. Further, for the case of the pressure transmitters (with the exception of PT-103) the safety function is over within the first few minutes and, consequently, they would not be subject to the full LOCA doses.
In the case of the ASCO solenoids, further evalu-ation on their acceptability will be conducted.
