For each safety-related syste=, sub=1t a list of design docu=ents, including title, identification nu=ber, revision and date, which were sources of input information for the seis=ic analyses. Also, sub=it s. description of the seis=ic a=alysis input infor=ation which is contained in esca dc.cu=ent.
Identify systems or portions of systems which are planned to be inspectd during each sequential inspection identified in Ite=s 2 and 3 Suh=it all of this infor=ation within 30 days of the date of this bulletin.

I'! SPEC *IC:7 ElEE"!"'S Faragraph 1 o' " '" etin 79-1k requests " identification of inspection ele =ents to te used in verifying tha: the sei.ic analysis input infor=atien confer =s to e e actual configura:icn of safet,-related systems."
A two-stage progra: is scheduled. The first stage is inspection of nor ally accessible nenredundant systems and one set of redundant s', stems. If no significant deviations are found, this vill be reported and the second stage (inspection of the re=ainder) =ay not be cc=pleted.
The inspection elements are identified as follows:
A.
FOR ?IPI:iG SYSTIMS OVER 2 ::iCHIS 1.
Survey the actual installs e17_ng gec=etry, supports (location, function and clearance), valves and valve operators, including trpe, location ncd weight to verify that these ite=s confor= to design doci:=enta. Piping geccetry vill be ec= pared with fabricater isc=etries while supports, alves and crerators vill be ec= pared with fabricator drawings.
A variety of inspection =ethods vill be used, such as =easuring tape (or s'-'ar nessuring equip =ent) for piping gec=etry, visual ec=parison of piping supports with the support drawing, etc.
In-sulation vill not be re=cved to facilitate inspection.
2.
Cc= pare the inputs to seis=ic analysis with ce=posite drt. wings and with fabricator drawings.

2 The chart =ethod is conservative; therefore, 2-inch and under pipir; is excluded frc= this response and evaluation.
II.
DESIGH DOCtH EITS Paragraph 1 of II Sulletin 79-1!+ requests that a list of design docu=ents, including title, identification number, revision and date, which vere sources of input infor=ation for the seismic anal / sis for each safety-related system, be provided. Also requested is a description of the seis=ic design analysis input infor=ation which is contained in each document. The following is provided:
A.
PIPING GECMETRY Cc=puter seis=ic analysis was perfor=ed utili:ing the ec=posite area drawings listed in Appendix A.
3.
SIIS:1IC RESPONSI SPICTRA Appropriate ficor response spectra were developed and utill:ei in analysis of safety-related piping syste=s. These spec ra are being provided to the URC staff as part of the systenatic evaluation progra:
and, therefore, are not included.
C.
PIPING AND FITTING SCEIDLT.,ZS Data on piping and fitting schedules are listed in Document 5935-M-259, Revision 9 (12-20-78), " Piping Class S - -7."
Insulation infor:ation is also included in this docu=ent.
D.
PRESSURIS AND TEMPERATURES Data on pressure and te=peratures is listed in Docu=ent 5935-M-260, Revision T (10-20-78), " Piping Class Sheets."
I.
SU??CRT, VALVI. tid VA1VE OPERATCR DATA
'4 eights, type and other infor=ation related to pipe supports, valves and valve operators was taken fro various Vendor and Cvner drawings.
For exa=ple, valve outline drawings received frc= valve nanufacturers contain the valve weight, operator weight and di=ensions of operators.
Support dravings show the rigidity and load capability of pipe supports.
This infor=ation is on file.
III.
IDE'ITIFICATION OF SYSTEMS Applicable piping in the safety systems identified by tha N11sades FSAR, Appendix A, vill be evaluated except as follows:
A.
Radioactive vaste treat =ent piping evaluatien vill be confined to the gaseous syste= with the exception of a portien of thz liquid discharge release line, plus related contain=ent penetrations.
1052 057
3 3.
Plant instru=ent air piping evaluation vin be confined to the high-pressure air-operated valve syste= and containment penetrations.
Appendix 3 of this response lists the syste= drawings which include the specific lines being evaluated.
IV.
SCHEDULE FOR INSPECTION OF SYSTELS Appendix 3, lists those syste=s which have portions of seis=ic piping.
Appendix 3 also categori::es inspection of that portion of the syste= vhich has seismic piping as fo11cvs:
Category A - Inspection of "nor= ally accessible redundant portions will be co=pleted by August 31, 1979 The re=ainder of seis=ic piping vin be ec=pleted by October 30, 1979 Category 3 - Seismic piping portion of the syste= not *nor=any available. Inspection vin be ec=pleted by Cetcber 30, 1979 Category C - Nonredundant system. Inspection of *=cr: ally accessible seis=ic piping vin be ec=pleted by August 31, 1979 The re=ainder of the syste= vin be inspected by October 30, 1979
'Nor= ally accessible is defined (for these purposes) as syste=s that are outside contain=ent in radiation fields of less than 100 =r/h and less than 80% cf naxi=u permissible airborne concentration.
The Palisades Nuclear Plant is now scheduled for a refueling outage be6 n-1 ning in Septe=ber 1979 The October 30, 1979 date vin be extended to coincide with the end of the refueling cutage, if the outage ends after October 30, 1979 1052 058

r 3-1 APPENDIT 3 SYSTD1 DRNIIUGS, DESCRI? TION AND INS?ECTICH CAMRY Fifteen copies of drawings are being provided to facilitate NRC review. These drawings have the system name and "MEI?" prefix prior to the nu=erical designa-tion; eg, MEXP-201 shows the safety piping to be inspected for the Prd-a 7 Coolant Syste=, P&I M-201.
The MIXP series of drawings are being used.for evaluation per IE Bulletin 79-02 as ven as II Sunetin 79-14. Also, the MEXP series drawings denotes 2-inch and under piping as safety-related; however, 2-inch and under piping is excluded from the evaluation being performed for IE Bulletin 79-14.
