The Dynaflex Computer Program showed a maximum DBE stress of 15,870 psi in the line 10" L-22291 at hanger BF-200 due to a seismic event. This is with-in the yield stress for the pipe. Corresponding displacements were very small and would cause no problem. No large seismic stresses nor displace-ments will occur by removing snubber BIS-298E. The Computer Program showed a maximum DBE stress of 17,381 psi in Line 10" L-21325 near snubber BFS-44E.
This is also within the yield stress of the pipe.

SPECIFICATION DF6.1 - REACTOR CORE, DESIGN FEATURES The following discussion describes the design features which shall be incorporated in the reactor core:
Reactor Assembly (Remains unchanged)
Active Core (Remains unchanged)
Fuel 235 The fuel consists of fissile uranium highly enriched (93.15%) in U and fertile thorium. The initial fuel loading is about 773 Kg of uranium and 16,000 Kg of thorium. The initial core is loaded with 13 fuel compositions whose distribution within the core is designed to mock up the fuel content of the equilibrium cycle refueling regions and to shape the radial and axial power distribution. Fuel is designed for up to a six-year life. About one-sixth of the core will be replaced at each refueling interval. The fuel loading in a reload segment will be about 200 Kg of uranium and 2,300 Kg of thorium.
All uranium and thorium in the reference fuel elements is in the form of heavy metal carbide and pyrocarbon, referred to as coated fuel particles. The coatings form the primary fission product barrier. The coated fuel particles consist of two general types, fissile particles (TH:UC 2 ) and fertile (TH C2 ) particles. The fissile particles shall contain thorium and uranium in a weight ratio of about 3.6 to 1 (+1.2,
-0.2) of thorium to uranium. The fertile particles shall contain only thorium.
In addits an to the reference fuel elements, eight test fuel ele-ments are Laciuded in the reactor core. These eight test elements (FTEl-8) con .ain small quantities of test fuel particles that are in various ways different from the reference fuel. The description of the test fuel elements is contained in Table 6.1-1.
The coated fuel particles are bonded together with a carbonaceous material to form fuel rods. The fuel rods are completely surrounded and contained by graphite which forms the structural part of the fuel element and, in addition to the carbon contained within the fuel rods, also serves as the sole moderator. The reference fuel elements are fabricated from H-327 needle coke (anisotropic) graphite, as described in the Fort S t . Vrain FSAR, Section 3.0. The test fuel elements are fabricated from H-451 near-isotropic graphite in anticipation of quali-fying this material for future use in all reload fuel for the reactor.

Reason For Chante The Fort St. Vrain fuel specification was changed in 1971 to per-mit a reduction in the TH:U ratio from 4. 25 /1 (1 0. 5) to 3. 6/1 (+1. 2,
-0.2) However, a revision to the Technical Specifications was inad-vertently omitted. This change will correct that omission.
