Subject: Control of Heavy Loads in January 1978, the ',RC published NUREG-04l entitled, Progran -or the Resolution of Generic Issues Related to Nuclear Power 'lants -Report to Concress." As part of this procra,-, the TasL' Action Plan fzr Unresolved Safety Issue Task 'N;c. 4-36, "Control of Heavy Loads Near Spent Fuel," was issued.ý..!e have completed our review of load handlinc operatiors at nuclear Dower plants. A report describing the results of this review has been issued as NUREG-0612, "Zontrol of Heavy Loads at %uclear Power plants -Resolution of TAP A-36." This -eport contains several recornendations to be implemented by all licensees and applicants to ensure the safe handling of heavy loads.The purpose of this letter is to request that you review your controls for the handling of heavy loads to detern"ine the extent to which the cuidelines of Enclosure
1 are cresently satisfied at your facility, and:0 identify the changes and ,o-ifications that would be -equired in order to fully satisfy these guidelines.
To expedite your compliance wit" this request, we have enclosed the following: ,UREG-0'12, "Control of Heavy Loads at '-uclear Power Plants'" Enc'esure 1).Staff Position -Interim Actions for Control of Heavy Loads (Enclosure

1. Submit a report documenting the results of your review and the required changes and modifications.
This report should include the information identified in Sections 2.1 through 2.4 of Enclosure
3, on how the guidelines of NUREG-0612 will be satisfied.
This report should be submitted in two parts according to the following schedule:-Submit the Section 2.1 information within six months from the date of this letter.-Submit the Sections 2.2, 2.3 and 2.4 information within nine months.2. Furnish confirmation within six months that imc'zmentation of those changes and modi'ications you find are -essary will commence as soon as o;!ssible without waitlnc -zaff review, so that all such changes, beyond the above in..-i actions, will be completed within two years of submittal of Section 2.4 for the above report.Furnish justification within six months for any changes or modifications that would be required to fully satisfy the guidelines of Enclosure
1 which you believe are not necessary.
T-h :riteria in NUREG-0612 are also applicable to applicants for operating ii:e-ses.
Such applicants are expected to provide the information re:ues:ed by item 1 above and to meet the same schedule of implementation as i;icated in 2 above. Any item for which the implementation date is Drio- to the expected date of issuance of an operating license will be ccnsicered to be a prerequisite to obtaining that license.F^r !rv date that cannot be met, furnish a proposed revised date, jus:iication for the delay, and any planned compensating safety actions.zur4: the interim.'Zý

This special review should include the following for these loads: (1) review of procedures for installation of rigging or lifting devices and movement of the load to assure that sufficient detail is provided and that instructions are clear and concise;(2) visual inspections of load bearing components of cranes, slings, and soecial lifting devices to identify flaws or deficiencies that coulch lead to failure of the component;
(3) appropriate repair and replacement of defective components;
and (4) verify that the crane operators have been properly trained and are familiar with specific procedures used in handling these loads, e.g., hand signals, conduct o' operations, and content of procedures.

Dose calculations based on the termination or mi:iga:ion of radtolouical releases should be supported bv inf:--ra-tion sufficient tc demonstrate both that the ti=e ýelav assuzed is conserva:ive and that the syste-_ p:cvided to accomplish such termnna:ion or mitigation will :erform its safety function jpon demand (i.e.. tne system meets the criteria for an Engineered Safety Feature).
Specific infor-mation so proviced should include the follow:ng:
(1) Details concerning the loca:ion of accident sensors, parameters zonitcred and the values cf these parameters at which a safety signal will be initiated, sys:e= response t Ime (Including valve-operation time), and the total ti=e required to auto=atically shift fro= nor--al operation to isolation or filtra-tion following an accident.(2) A description of the ins:rumenta:ion and con-trols associated with the Engineered Safer: Feature which includes Infcrmation sufficien:

(4) A discussion of any initial conditions ,e.g., manual valves lo:ked shut, containment airlocks or equipment hatches shut) necessary to ensure that releases will be terminated or mitigated upon Engineered Safety Feature actuation and the measures employed (i.e., Tech-nical Specification and administrative controls)to ensure that these initial conditions are satisfied and that Engineered Safety Feature systems are operable prior to the load lift.2. METHOD OF ANALYSIS Discuss the method of analysis used to demonstrate that post-accident dose will be well within 10CFM00 limits. In presenting methodology used in determining the radiological consequences, the following informaticn should be provided.a. A description of the mathematical or physical model employed.b. An identification and sumary of any computer program used in this analysis.c. The consideration of uncertainties in calculational methods, equipment perfor=-ance, instrumentation response characteristics, or other indeterminate effects taken into account in the evaluation of the results.3.

(3)CRITICALITY
ANALYSIS The following information should be provided for analysis conducted to demon-strata compliance with Criterion II of NUMEG 0612, Section 5.1 1. INITIAL CON'DITIONS/ASSLWTIONS
The conclusions of NUR.G 0612, Section 2.2, are based on a particular model fuel assembly.
If a licensee uses the results of Section 2.2 rather than performing an independent neutronics analysis, the assump-tions should be verified to be compatible with plant-specific design.For any analysis conducted, the following assumptions should be provided as a minimum: a. Water/UO 2 volume ratio b. The boron concentration for the refueling water and spent-fuel pool c. The amount of neutron poison in the fuel d. Fuel enrichment e. The reactivity insertion value due to crushing of the core f. T-he kIfc value allowed by technical specifications for t~e core during refueling 2. .MTHOD OF ANALYSIS Provide the method of analysis used to dezonstrate that accidental dropping of& heavy load does not result in a configuration of the fuel such that keff is larger than 0.95. The discussion of the method of analysis should include the following infortation:
a. Identification of the computer codes employed b. A discussion of allowances or compensation for calculation and physical uncertainties
3. CONCLUSION
Prov.de an evaluation co=paring the results of the analysis to Criterion II of LKUREG 0612, Section 5.1. If the postulated heavy-load-drop accident 3-1 MM-,
bounds other postulated heavy-load drops, a list of these bo'--.ded heavy loads should be ;rovided.
