Illinois Power Company Clinton Power Station Unit'l' Attachment to-U-0618 3/18/83)*

(

Section 2.1 of Reference 4 indicated that- Illinois Power:

Company had not clearly specified the weight of>a beavy load-for  ;

.the Clinton Power Station.' NUREG-0612, Section-l.2 defines a heavy load as "the combined. weight-of.a single. spent fuel I assembly ~and its. associated handling tool..." which is approximately 1000 pounds for Clinton Unit 1.

Design has started on two new cranes since Reference 3 was . t

-submitted in 1981. .They are the Fuel Channeling ~ Hoist and the (

Screenhouse Trash Basket Hoist. Theinecessary.information-on- 1 these hoists, as well as the Auxiliary Roof Gantry Crane (RHR t.

Heat-Exchanger Removal Hoist) and the Fuel Transfer Tube Shield'

. Plate Jib Crane, will be submitted upon completion of the designs.

Per the telephone conference (reference 5), Illinois Power confirms'that all the drawings relevant to the-study on Control z.

of Heavy Loads are included in the-set of drawings which were .l

! submitted with Reference 2. l

. i; The below listed responses-to the Guideline Recommendations of Section 3.2 of Reference 4 apply to the plant cranes listed in Table 2.1 of Reference 4 with the following exceptions: l V

(i) Cranes 2, 7-and'9'of Tablez 2.lL(reference 4) do'not }

handle heavyLloads.

(ii)'Other-plant cranes of Table 2.l'that may be eliminated  !

from the full scope of NUREG-0612 by further IP j evaluation the ~ elimination of which can be justified and demonstrated for NRC Staff concurrence.

Guideline Illinois Power Action

1. (Section 2.3.1) a, b Safe load paths for each heavy-load handled by each ' crane will be developed. Drawings or sketches will depict each load path in its entirety, with all nearby' safe shutdown equipment-and irradiated fuel areas high-lighted.

Action: Documentation will be provided to the NRC for review, and a copy will be available at the site at least 6 months prior.

to fuel loading.

Guideline Illinois Power Action

c. Safe load paths for each crane will be marked clearly on the plant floor.

Action: Daths will be marked before fuel loading.

d. Administrative controls will be provided as required to prevent deviation from the prescribed load paths.

Deviations will require approval of the plant safety committee or their designee.

Permission for deviation may bc oral, but subsequently shall be documented in a brief description which will be kept t in permanent plant records.

Procedures shall include a statement relating to the avoidance of undue hazards, especially for safety related equipment and cable trays, for cranes in which the entire load paths are not visible from the operating station.

Action: Documents will be developed and available at the site before fuel loading.

2. (Section 2.3. 2) a,b. Procedures for each overhead heavy load handling system (including single faflure proof) will be completed.

Action: Procedures will be completed and available at the site before fuel loading.

3. (Section 2.3.3) a. Training curricula and operator qualifications will be documented.

Attachment to U- 0618 March 18, 1983 Page 3 Guideline Illinois Power Action Action: Documentation will be available at the site 6 months prior to fuel loading.

Initial training will be completed 2 months prior to fuel loading.

4. (Section 2.3.4) a,b. The applicable standards of ANSI N14.6-1978, as amended by NUREG 0612 Section 5.1.1(4) will be compared to the standards imposed on Clinton's RPV head, drywell head, stean separator and steam dryer strongbacks.

Action: Documentation will be sent to the NRC for review at least 6 months prior to fuel loading.

5. (Section 2.3.5) a,b. It will be demonstrated that all slings used for heavy load lifts meet the applicable requirements of ANSI B30.9-1971, as amended by NUREG-0612 Section 5.1.l(5).

Action: Documentation will be available on site at least 3 months prior to fuel loading.

6. (Section 2.3.6) a,b. Procedures for crane inspection, testing, and maintenance will be developed in accordance with Chapter 2-2 of ANSI B30.2-1976, with the exceptions described in Section 2.3.6 of Reference 4.

Action: Procedures will be written before fuel loading.

7. (Section 2.3.7) a. Compliance claims for crane design will be documented.

Action: Documentation will be available on site at least 6 months prior to fuel loading.
