While a ge may be exuerienced due to bubble compression (especially at pressure su: excessive f: 11 rates), a sharp rise in pressure above saturation pressure ef about 10: to 200 psi will be an indication of being colid. When solid, pressurizer pressure will change by approximately 13 psi for every 10 gallens added to the RCS. 3.3 Monitor temperature indication downstream of primary pressure relief,.alves prior to raising level and following solid condition to determine if any significant change in leakage has b2en made as a result of going solid. 3.4 Cic3ely monitor the natural circulation data collected for RCS parameters to ensure criteria established for satisf actory natural circulation continues to be met. '(Re fer to Reference 2.6.) 3.5 Carefully mcnitor pressure while heaters are energized when solid. (Refer to Re f e rence 2., upon the loss of pressure indicator.) 3.6 Closely moni toc Makeup Tank pressure and Auxiliary Building ventilation radiatior monitors. Reduce letdown flow if Makeup Tank pressure exceeds 2 psig or a noticeable rise in activiry levels is detercined on the radiation monitor. Comply with the Makeup Tank addition rates established by J. G. Herbein. NOTE: The response of the radiation monitor to an increase in Makeup Tank Room activity will be delayed. 3.7 Observe the NDTT liuits'of Figure 2. ~ 257 346 ~

Initiation may violate NDTT lisdts or cause other RCS pressure boundary f ailures. 4.1.5 Low Pressure Saf ety Injection System shall be available for automatic or manual actuation to prevent total depressurization acaldents. 4.1.6 MU-V8 aligned to MU Tank. 5.0 SPECIAL EQUIPMENT 5.1 None 6.0 METHOD 6.1 Taking Pressurizer Solid NOTE: The pressurizer fill rate of about cne inch of MU Tank level every three minutes is selected to utilize approximately 500 KW of pressurizer heaters for the 10 gpm if cdded to the o ressurizer. Fill rates should not exceed about 15 gpm to prescive an adequate heater reserve to control pressurizer temperature. (This is for information only and not to be used as a limit.). NOTE: If an overpressure condition is experienced, a t t e =p t to lower pressure by: 1. C10 sing MU-V-17 and MU-V-18 to is>iate normal makeup, and if necessary; 2.

Operate. pressurizer heaters as follows: A. Initially leave control group as is at beginning of test. (Expect initial presr.are rise approximately 13 psi /,hr.) = B. When pressurizer pressure begins to decrcase (drops 5 psi' below highest previous pressure)', energize backup h.-ater bank'. C. Use the pressurizer' heaters to maintain pressure within 25 psi of the saturation p ressure corresponding to the initial pressurizer temperature. D. Monitor and control the tecperature o' the pressurizer within a control band between the initial pressurizer tecperature at which it was.at prior to filling and 10* below that tempera-ture (i.e., T initial +0 )'. -10*F NOTE: If it is icpossible 'to maintain this tecperature with all heaters energized, reduce the rate at which the pressurizer is being filled until this criteria can bt met. lf not possible to maintain tecperature within .10*F of its initial temperature, raise pressuri2er level in a series of small, step changes allowing pressurizer tecperature to return to within 20*F. Figure 1 is a typical acceptable operating range. 6.1.4 When MU tank level reaches approximat '" 30", secure raising pressurizer level. a 6.1.5 Refill the MU tank from the degassed source with appropriate boron addition to 50" {in the :MU" tank. 6.1.6 Monitor pressurizer temperature.

NOTE: Vnen first taken solid (i.e., pressure r narply increases approximately 100 to 200 psi.bove initial pressure), the Pressurizer may cantain a superheated, highly co= pressed steam bubble. This bubble will act as an ideal gas while superheated and will slowly (possibly over several hours) collapse due ' to-cooling through ru_ -, ambient. losses.and leakage.
