Experiments that.could increase reactivity by l flooding, shall not remain in or adjacent to the i core unless the shutdown margin required in Specification 3.1.1 would be satisfied after flooding.

l Bases:

The shutdown margin required by Specification 3.1.1. i assures that the reactor can be shutdown from any operating condition and will remain.suberitical after cooldown and xenon decay even if the rod of the highest reactivity worth should be in the' fully withdrawn position. Specification 3.1.2 limits the allowable excess

l reactivity to the value necessary to overcome the combined negative reactivity effects of: (1)'an increase in primary coolant temperature from 90 F to 116 F; (2) fission product xenon and samarium buildup in a clean core; (3) power defect due to. increasing from a zero power, cold core to a 2 Mw, hot core; (4) fuel burnup during sustained operation for 30 days; and i

(5) moveable experiments. [ t Specification 3.1.3 limits the individual reactivity 1 worth of moveable experiments to values that will not l38 produce a stable period of'less than 30 seconds and which can be compensated for by the action of the control j and safety systems'without exceeding any safety limits. Specification 3.1.3 limits the reactivity. worth of. 38 secured and total experiments to values of-reactivity which, if introduced as positive step changes, will not cause fuel melting. Specifications 3.1.4 and 3.1.5 provide assurance that the core will remain suberitical during fuel movements 38 to and from the core and during shim-safety rod maintenance or inspection. The largest positive reactivity increase thatican be l33 i produced by replacing light water with heavy water in the heavy water reflector tank is 0.04 delta K/K. Maintaining the core suberitical by at.least 0.010 38 delta'K/K in Specification 3.1.6.during heavy water transfers provides adequate margin to assure that. Page 11 j

The building exhaust air radiation monitor shall i be operating whenever the reactor is in operation as required by Table 3.2 of i specification 3.2. Bases: i The limits established in specification 3.5.1 l38 incorporate a dilution factor of 400 for effluents l l-released through the exhaust stacks. This dilution Li factor was calculated from actual FNR site -i meteorological data and represents the lowest dispersion factor determined and the highest frequency of wind in j any sector. Pecause of the use of the most conservative i measured values of wind directional frequency and I dispersion factors, this dilution factor will assure that concentrations of-radioactive material in unrestricted areas around the FNR site will be far l below the limits of 10CFR20. 4 l effluent monitoring.l38 The requirements of specification 3.5.2 are considered adequate to assure proper airborne 3.6 Liquid Effluents i Applicability: This specification supplies-to the monitoring of radioactive liquid effluents from the FUR.

The concentration of radioactive materials in the effluent released from the facility liquid waste. system to the city of Ann Arbor sanitary sewer system shall be readily soluble (or readily 40 dispersible biological material) in water and shall not exceed 315 times the t concentrations specified in 10CFR20, Appendix B, Table 3, Releases to Sewers. 2. The amount of liquid discharged shall be limited l33 to the equivalent of 3,000 gallons of liquid at the concentration limit specified in 3.6.1 each day. l38 l 3. Liquids from the facility's radioactive liquid waste r system shall not be discharged into the storm drain system. i Bases: j All radioactive liquid effluents are collected in a series of three, 3,000 gallon, coated, steel [ retention tanks, and they are normally recycled to the 40 i reactor pool to make up for surface evaporation. However, after sampling, analysis, and dilution, if the [ concentration of radioactivity is less than the limit l of 10CFR20, liquid effluents can be-discharged to the sanitary sewer system. In the past, less than 50 retention tank discharges 38 3 per year have been required. During 1970, the North l Campus water released into the sanitary sewer system averaged 946,000 gallons per day. This provides a daily dilution factor of 315 for a 3,000 gallon waste tank, l which assures that there will be no significant exposure -i to the public from radioactive waste discharged to the l sanitary sewer system. l 3.7 Limitations of Experiments l l Applicability: J This specification applies to experiments installed in i the FNR.

The calculations for experiment radioactivity limits are provided in section 14.3 of the SAFETY ANALYSIS. 3.8 Fission Density Limit Applicability: l This specification applies to fission density limits f in FNR fuel. j Objective: To prevent fuel plate swelling which could result in l clad rupture and release of radioactive fission I products. ( Specification: } 1. The FNR fission density limit shall be 1.5x1021 f fission /cc. j Bases: The fission density limit is below operational fission densities reached in other operating reactors using the same kind of fuel without failures attributed to the fuel. An experimental data base that supports the safe use of uranium aluminide (UAlx), uranium oxide ( U3 0s ), and l uranium silicide (U3 Siz ) fuel in the FNR up to the l34 fission density limit was derived from irradiation tests [ performed in the Materials Test Reactor (MTR), the Engineering Test Reactor (ETR), and the Advance Test Reactor (ATR) at the Idaho National Engineering . the j Laboratory, the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory, and the German Karlsruhe l FR2 reactor. i Page 23 .m..

Ford Nuclear Reactor i Docket 50-2, License R-28 Amendment-40:080193 l Bases. s Specification 4.1.1 will assure that shim-safety-rod reactivity worths are not degraded or changed ~by core arrangements. Shim-safety rod inspections are the single, largest' source of radiation exposure to facility' personnel. Furthermore, fregaent inspections of shim-safety rods for swelling over ti.e last ten years have produced no evidence of swelling or cracking. In order to minimize personnel radiation exposure and provide an inspection l frequency that will detect early evidence of swelling t and cracking, an annual inspection interval was selected for Specification 4.1.2. l The specified surveillance relating to the reactivity worth of experiments will assure that the reactor is i not operated for extended periods before determining i the reactivity worth of experiments. This specification j also provides assurance that experiment reactivity worths do not increase beyond the established limits due to core configuration changes.
