We telecopied the guidance to your staff on February 24,1982 and i
March 8,1982. As per a telephone call on Itarch 16, 1932 between T. Patterson of your staff and E. Tourigny of my staff, it was requested that we formally transmit the guidance to you.
It is our understanding that you would like the guidance formally sent in order to help justify the additional cost associated with this work. Enclosed is the guidance. After you have reviewed this i to provide your supplementary infomation@.h: us of when you will be able infomation, we would appreciate your 7 Please contact us if you have any questions concerning this letter.
Sincerely, Onginal signed by Robart f( C.iark Robert A. Clark, Chief Operating Reactors Branch #3 Division of Licensing

TER-CS257-439 deline 4 is to apply the criteria of ANSI N14.6-1978 to all special liftia devic which carry heavy loads in areas defined in NUREG-0612. As a m. mum, Lifting de ' es used to transport the reactor vessel head and missi shields should be evalu ad for compliance with this standard, as wel' s any other special lifting dev the Licensee may identify. Furt
, while recognizing
'ent "uel casks are not p ently in use, FRC does
- hat lifting devices for f
iot concur with the Licensee's - tent to defer dressing the design of this Lif ting device. The need for analy s of
.e spent fuel shipping cask lifting device is based on the fact that thi re w by FRC constitutes the only
' comprehensive evaluation of loa.andling pra ' ices at the N
and therefore all issues s uld be resolved either compliance with the guideline or, in the se of non-compliance, by i=pleme ation of suitable corrective acti within a reasonable period of time so tha no unresolved
.tems are d erred to a future unspecified date. Taerefore, the censee aboul ommit to comply with ANSI N14.6-1978 prior to use of this lift' ice.
)
FRC has evaluated the criteria cf ANSI N14.6-1978 and notes that it is g
difficul( to make a strict interpretation of compliance between that standard and existing special lifting devices. FRC has no objection to addressing only those sections which are directly related to load handling reliability of the lifting devices. Further, FRC notes that the following sectic'ns are not pertinent nor do they contain requirements which affect load handling
~
reliability: Scope (Section 1), Definitions (Section 2), Design Con.3iderations to Minimize Decontamination Efforts (Section 3.4), Coatings (Section 3.5),
Lubrication (Section 3.6), Inspector's Responsibilities (Section 4.2), and Fabrication Considerations.Section 4.3).
In addition,.FRC notes that Section 6 (Special Lif ting Devices for Critical Loads) need not be included in this review since none of the loads identified by the Licensee has been determined to be a " critical load" at present.
I Evaluation and review of ANSI N14.6-1978 by FR': has identified several areas where load handling reliability is an issue. It is FRC's judgment that certain sections (3.1, Designer's Responsibilities; 3.2, Design Criteria; 3.3, nk5n Research Center
^"M~~
6 TER-C5257-439 Design Considerations; 4.1, Fabricator's Responsibilities; and 5.0, Acceptance Testing, Maintenance, and Assurance of Continued Compliance) identify important'
~
information which should be readily available or requirements to which the Licensee should adhere in order to adequatel*/ sub-tantiate the load handling reliability of the special lifting devices. Although this standard may not i
have existed when lifting devices were designed and m'anufactured, it is not anticipated that procurement of information or compliance with the stan'dard's criteria will create undue hardship since the criteria of the standard are akin to established industry practices and this standard codifies such practices for special lifting devices. Further, these special lifting devices
~-
are used for infrequent lif ts of the plant's largest cc=ponents, generally in the direct vicinity of,. irradiated fuel, which maxes the reliability of design, f abrication, and continued testing of the special lif ting devices a relatively sensitive concern.
It has been determined that compliance with Guideline 4 requires that the following specific sections of ANSI N14.6-1978 be addressed:
T'~ Section 3.1:
.a.
limitations on the use of the lif ting devices (3.1.1) b.
identification of critical components and definition of critical characteristics (3.1.2) signed stress analyses which demonstrate appropriate margins c.
of safety (3.1.3) d.
indication of permissible repair procedures (3.1.4)
Section 3.2:
use of stress design factors of 3 for minimum yield strength a.
and 5 for ultimate strength (3.2.1) b.
similar stress design factors for load bearing pins, links, and adapters (3.2.4) slings used comply with ANSI D30.9-1971 (3.2.5) c.
d.
subjecting materials _to dead weight testing or Charpy impact testing (3.2.6)
Section 3.3:
consideration of problems related to possible lamellar a.
tearing (3.3.1) b.
design shall assure even distribution of the' load (3.3.4) retainers fitted for, load carrying components which may c.
become inadvertently disengaged (3.3.5)
. nkun Research Center A C>nnen of N Fearman swansse
TER-C5'257-439 d.
verification that remote actuating mechanis=s securely engage or disengage (3.3.6)
Section 4.1:
verify selection and' use of material (4.1.3) a.
b, compliance with f abrication practice (4.1.4) qualification of we10ers, procedures, and operators (4.1.5) c.
d.
provisions for a quality assurance program (4.1.6) provisions for identification and certification of equipment s.
(4.1.7) f.
verification that materials or services are produced under I
appropriate controls and. qualifications (4.1.9).
Section 5.1:
implementation of a periodic testing schedule and a system to a.
indicate the date of expiration (5.1.3) provisions for establishing operating procedures (5.1.4) b.
identification of subassemblies which may be exchanged (5.1.5) c.
d.
guitable markings (5.1.6) maintaining a full record of history (5.1.7) e.
f.
conditions for removal from service (5.1.8)
Section 5.2 load test to 150% and appropriate inspections prior to in,itial a.
use (5.2.1) b.
qualification of replacement parts (5.2.2) 4 Section 5.3:
satisfying annual load test or inspection requirements (5.3.1) a.
b.
testing following major maintenance (5.3.2) testing af ter application of substantial stresseg (5.3.4) c.
d.
inspections by operating (5.3.6) and non-operating or maintenance personnel (5.3.7).

FRC Conclusions and Recommendations
~
Insufficient information has been provided by the Licensee fo'r FRC to determine ecmpliance with Guideline 4.
In order to demonstrate full-
- ompliance, the Licensee should perform the following:
1.
Identify and evaluate all special lifting devices, with respect to
~
those items identified in the FRC evaluation as affecting load handling reliability, and report the results of this review to the ERC' r
2.
For the spent fuel shipping cask lif ting device, commit to perform the evaluation of those items noted in FRC's evaluation prior to use of the lif ting device.
