TESTIMONY OF GARY G. ZECH CN CONTENTION 2(f)(1)
Contention 2(f)(1) states:
There has been insufficient deve.ocment of credible accident scenarios.
For example:
(1)
There is insufficient documentation to establish the methods by wnich the Applicant will cositively prevent the movement of heavy objects, such as shipoing casks or empty fuel racks over the ocol during modification; thus, accidental dr00 pings of such heavy objects, which would lead to un-acce; table damage to snent fuel or the :: col liner and Ocnsecuent release of radionuclides, has not been crecluded.

a shipping cask.
I sucervised the preparation of and contributed to portions of Section 2.3 and adoot it as part of., direct testimony on Contention 2(f)(1).
As indicated in Section 2.3, the licensee nas committeed to not handle heavy loads in the vicinity of the scent fuel storace pool without first notifying the NRC.
In addition, we indicated that, orior to issuing a license amendment authorizing the expansion of the spent fuel pool storage capacity, we intend to impose a technical scecification restriction to preclude the handlina of any loads greater thar. a single fuel.issembly (olus handling tool) over stored spent fuel.
These restrictions will creclude the movement of a shiccing cask or empty fuel racks over s;ent fuel durina and after the pool modification.
With regard to the potential for unacceptable damage to the cool liner, in our Safety Evaluation related to oceration of the Zion Station, dated October 1972, we c;ncluded that any ccssible loss of water from the ccol due to a cask drop and resultant breech of the liner would be within the makeup caoacity of ay leakage fran the liner would be col-
