3. INTRODUCTION Narora Atomic Power Station (NAPS) is a  nuclear power plant  located in the bank of river Ganga,  Narora ,  Bulandshahar  District in  Uttar Pradesh ,  India . Narora atomic power plant is involved in generating electricity by utilizing nuclear energy. Laid down on 4 th January 1974. The heat generated due to fission of natural Uranium is removed by circulating D 2 O coolent . It has 2 natural draft cooling tower and 2 induced draft cooling tower. The plant house has 2 reactor and each has a capability of producing 220 MW It has been placed under IAEA monitoring

6. PRINCIPAL OF NUCLEAR REACTOR A Nuclear Power reactor is only a source of heat. The heat being produced when the uranium atom splits (fission) Natural uranium consist of two types of uranium namely U-235 and U-238 in ratio of 1:139. Naturally occurring uranium contains only 0.71% U-235,the remainder Is the non feasible U-238 When a U-235 atom is struck by a slow (or thermal) neutron, it splits into two or more fragments.

7. REACTOR TYPE IPHWR-220 (Indian pressurized heat water reactor) Primary coolant material: Heavy Water Secondary coolant material: Light Water Moderator material: Heavy Water Fuel: Sintered Natural UO, pellets Enrichment of reload fuel: 0.7% U-235 Residual heat removal system, Active: Shutdown cooling system Safety injection system: Emergency core cooling system Thermal output 754.5 MW, Active power 220 Mwe,Efficiency 27.8% Core coolant inlet 249*C Core coolant outlet 293.4*C Reactor operating pressure 87 kg/cm2 (g) Active core height 508.5 cm Equivalent core diameter 451 cm Average fuel power density is 9.24 KW/ KgU Average core power density is10.13 MW/m3

8. UNIT 1:NARORA-1 First criticality was at 12 March 1989 Reactor is Pressurized Heavy Water Reactor (PHWR) Model is horizontal pressure tube type Owner and operator is Nuclear Power Corporation Of India Ltd Net capacity is 220 MW

9. UNIT 2:NARORA-2 First criticality was at 24 October 1991 Reactor is Pressurized Heavy Water Reactor (PHWR) Model is horizontal pressure tube type Owner and operator is Nuclear Power Corporation Of India Ltd Net capacity is 220 MW

10. SUMMARY Narora Atomic Power Station is the fourth Nuclear Power Station having twin units each of 220 MWe capacity. It is situated on the bank of river Ganga at Narora in District, Bulandshahr (U.P.) & is 140 km. ... It is the first standardized and totally indigenous PHWR type Nuclear Power Station. Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.
