The inspector discussed the seismic monitoring program with responsible engineers, examined seismic monitoring equipment and reviewed procedures for surveillance of seismic monitoring equipment. The equipment consists of two SMA-2 Triaxial Time History Accelerographs. Recorder A is located inside the containment purge inlet structure and Recorder B is. located south of the waste retention basin. The recorders are set to trip at

.05 The operating base earthquake is based on the fact that the site area could experience a shock in the order of the 1959 McBee earthquake once during the life of the plant. A magnitude of 4.5 earthquake was selected with an epicentral distance of less than ten miles was selected as the Operating Base Earthquak This is based on a ground acceleration of 0.1g, even though the probable ground acceleration is expected to be in the.07g to.09g rang The safe shutdown earthquake is based on a hypothetical earthquake with a ground acceleration of 0.2 Procedures reviewed by the inspector for surveillance of seismic equipment are as follows:

MST-904 Seismic Recorder Operation, Monthly Interval MST-905 Seismic Recorder Calibration, Semi-Annually Review of these procedures and the most recent surveillances showed that FSAR and Technical Specifications for seismic monitoring were being me.

Independent Spent Fuel Storage Installation (T10110/4)

The inspector examined QA/QC controls and work activities for placement of the concrete pad for the Horizontal Storage Module (HSM).

The HSM is a reinforced concrete structure for dry storage of spent nuclear fue The nuclear fuel assemblies will be placed in stainless steel dry shielded canisters (DRC)

which will be stored in the HS These facilities are being constructed to provide additional interim storage capacity for the spent nuclear fuel. The HSM is committed to the requirements specified in

CFR 72, Licensing Requirements For Storage Of Spent Fuel in an Independent Spent Fuel Storage Installation. Subpart G, Quality Assurance of 10 CFR 72, requires a quality assurance program based on the criteria in Appendix B of 10 CFR 5 Areas examined during this inspection to verify that these requirements were being met were as follows: Review of Quality Implementing Controls examined by the inspector included the following specification, procedures and drawings:

Observation of Concrete Placement Operations The inspector observed preplacement preparation and placement operations for the concrete slab. Preplacement observations included verifying that forms were tight, level, and had the proper dimensions; that the size, number and spacing of reinforcement steel and steel supports complied with drawing requirements; and that the placement had been properly cleane Observation of placement activities showed that the placement was continuously monitored by construction engineers and QC inspectors and that activities pertaining to delivery time, freefall flow distance, layer thickness, and consolidation conformed to specification requirement Samples of plastic concrete were obtained from designated sampling points and were tested in accordance with procedure requirement Test results indicated that the plastic concrete being placed met the specifi cation requirements for slump, air content, unit weight and temperature observations of the making of test cylinders used to verify the strength of the concrete being batched showed they were being made and field cured in accordance with specification requirement.
