. Nuclear Plant Operations P.O. Box 1700 Houston, Texas.77001 Gentlemen:
We have conducted an initial review of your June 14,'1985, application to receive and store unirradiated nuclear fuel assemblies. To complete our review, we need supplemental information as described in the enclosure.
c These issues have been discussed with your Mr. Walker. -Your prompt response.
should enable us to complete the licensing action prior to August 15, 1986.
Sincerely, Originni sinned MT George H. Bidinscr G. H. Bidinger Uranium Process Licensing Section Uranium-Fuel Licensing Branch Division of Fuel Cycle and Material Safety, NMSS

EAR 2 41986 SUPPLEMENTAL INFORMATION REQUEST HOUSTON LIGHTING & POWER COMPANY (HL&P)
APPLICATION ~ DATED JUNE 14, 1985 FOR UNIRRADIATED POWER REACTOR FUEL 1.
Please identify the individual, e.g., station manager, who has overall responsibility for nuclear criticality and radiation safety and provide the minimum education and experience requirements for the position.
2.
Minimum Qualifications for Reactor Performance Supervisor Position The proposed minimum qualifications for this position should be provided.
Please note we require as a minimum, that a person who is delegated the responsibility-for nuclear criticality safety including the establishment of written procedures for fuel handling and storage, must possess, a bachelors degree in physical science or engineering and have 2 years of experience as a manager in related nuclear activities.
3.
Training Training, as required by 10 CFR 19 and in use of approved written procedures for fuel handling, should be described and established as a requirement of the license. All personnel involved in fuel handling and storage activities must be trained before initiation of such activities.
4.
Nuclear Criticality Safety a.
The application should specify either th.at the plastic dust wrapper on the fuel assembly'will be removed immediately when the assembly is removed from the shipping container or that the dust wrapper will be maintained in a' condition which will permit draining of any water which may get inside the wrapper, b.
We are unable to confirm the nuclear criticality safety analysis for fuel assemblies in the racks in the new fuel storage pit. The storage rack module's characteristics, e.g., materials of construction, inside dimensions, and wall thickness of the module are needed to verify your k-effective of the storage array. The cell spacing'between modules as well as within a module should be provided.
c.
The storage cell's characteristic in the spent fuel pool racks need to be described so that your k-effective calculations can be verified.
d.
We do not accept k-effective values of 0.98 for low-density moderators because of lack of data for validation of calculation methodology at reduced moderator density.
It is necessary to show that the k-effectives for both storage arrays are lower than 0.95, or controls to exclude the moderator will have to be established as conditions of the license.
