PPL Rev. 6 Reactor Core. SLs B 2. 1.1 B 2.0 SAFETY LIMITS (SLs)

B 2.1.1 Reactor Core SLs BASES BACKGROUND GDC 10 (Ref. 1) requires, and SLs ensure' that specified acceptable fuel design limits are not exceeded during steady state operation, normal operational transients, and anticipated operational occurrences (AOOs).,

The fuel cladding integrity SL is set such that no significant fuel damage is, calculated to occur if the limit is not violated. Because fuel damage is not directly observable, a stepback approach i's used to establish an SL, such that the MCPR is not less than the linmit specified- in Specification 2.1.1.2 for AREVA NP fuel. MCPR greater than the specified limit represents a conservative margin relative to the conditions required to maintain fuel cladding integrity.

The fuel cladding is one of the physical barriers that separate the radioactive materials from the environs. The integrity of this cladding barrier is related to its relative freedom from perforations or cracking.

Although some corrosion or use related cracking may occur during the life of the cladding, fission product migration from this source is incrementally cumulative and continuously measurable. Fuel cladding perforations, however, can result from thermal stresses, which occur from reactor operation significantly above design"conditions.

While fission product migration from cladding perfbration, is just as measurable as that from use related cracking,. the thermally caused.

cladding perforations signal a.%thr6shOld beyond which still'greater thermal stresses may cause gross, rather th6n: ~crenental,. claddj*.. detbriQration.

Therefore, the fuel cladding SL is defined wi'-h 'a margin to the condinio*s that Would produce onset of transition b6iling (i.e., MCPR.= 1.00). These condioons represent a significant de*aftu~e from the condition intended by design for planned operation. Th. MCP fuel cladding integrityýSL.

ensures that during normal operation: a'iddurirng Aoos, at'least 99.9% of' the fuel rods in the core do not exp0erience transition boiling.
